Answer:
You can actually draw both points in a graph to find out as it makes it easier to understand. Or you could think, if C has moved from (0,0) to (-2,3). It means it moves to the left of the x axis by 2, then moves up by 3 on the y axis.
So point P should move the same way. (-3, 4) move by -2 on the x axis would make it -5, and for y you go up 3 steps so 4+3=7 making P's final location (-5,7)

3x + 4y = –20
6x + 5y = –7
Answers
Answer:
x = 8
y = -11
Step-by-step explanation:
In this question, we have to find out the value of "x" and "y".
Solve:
Lets solve for y first.
-2(3x + 4y = -20)
6x + 5y = -7
------------
-6x - 8y = 40
6x + 5y = -7
------------
-3y = 33
Divide both sides by -3
y = -11
We now know what the value of "y" is, now we must find the value of x. To do this, we would plug -11 to "y" in one of our equations.
Solve for x:
3x + 4y = -20
3x + 4(-11) = -20
3x - 44 = -20
Add 44 to both sides.
3x = 24
Divide both sides by 3
x = 8
Now we know that our answer are:
x = 8
y = -11

m% of n =
What is m% of n
please send steps
Answers
Answer:
m%(n)
Step-by-step explanation:
whenever the word "of" comes up in a math problem, it's going to mean to multiply. This case is no exception.
m% of n = m%(n)
n=number
m=the percent number
Ex: m=25
n=315
plug the values into m%(n)
25%(315)
There are two different forms you can do to solve this expression.
fraction: 25/100(315)=7875/100=78.75
the reason why it would be 25/100 hundred is because, %=per cent. Cent=100 and per would mean you would have to divide.
decimal: 0.25(315)=78.75
if 25% is 25/100 that means that 25 would be in the hundreths place in a decimal(0.ab)

Answer:
3
Step-by-step explanation:
"Find a number which, when added to 3, yields 7"
may be written as:
3 + ? = 7, 3 + n = 7, 3 + x = 1
and so on, where the symbols ?, n, and x represent the number we want to find. We call such shorthand versions of stated problems equations, or symbolic sentences. Equations such as x + 3 = 7 are first-degree equations, since the variable has an exponent of 1. The terms to the left of an equals sign make up the left-hand member of the equation; those to the right make up the right-hand member. Thus, in the equation x + 3 = 7, the left-hand member is x + 3 and the right-hand member is 7.
SOLVING EQUATIONS
Equations may be true or false, just as word sentences may be true or false. The equation:
3 + x = 7
will be false if any number except 4 is substituted for the variable. The value of the variable for which the equation is true (4 in this example) is called the solution of the equation. We can determine whether or not a given number is a solution of a given equation by substituting the number in place of the variable and determining the truth or falsity of the result.
Example 1 Determine if the value 3 is a solution of the equation
4x - 2 = 3x + 1
Solution We substitute the value 3 for x in the equation and see if the left-hand member equals the right-hand member.
4(3) - 2 = 3(3) + 1

The length of the sides of ΔEFG are 144, 128, and 112. The length of the smallest sides of ΔQRS is 280. What is the length of the longest side of ΔQRS?
Answers
______________________________________________
The length of the longest side of ΔQRS is: " 355 " .
______________________________________________
Explanation:
______________________________________________
Given:
_________________________________________________
The smallest side of ΔQRS is 280.
_________________________________________________
In ΔEFG, the smallest side is 112 {compared to "144" and "128"}.
The longest side length of ΔEFG is "144" {compared to "128" and "112"}.
What is the length of the largest side of ΔQRS ?
Both triangles are similar, so the following ratios can be set up to solve the problem:
(the smallest side length of ΔEFG) / (the smallest side length of ΔQRS) =
(the longest side length of ΔEFG) / (the longest side length of ΔQRS) ;
__________________________________________________________
→ 112/ 280 = 144 / (the longest side length of ΔQRS);
We wish to solve for "(the longest side length of ΔQRS)" ;'
for which we shall represent with the variable, "x" ;
___________________________________________________
→ Rewrite as: 112/280 = 144/ x ;
Reduce "112/180" to: "2/5" ;
and rewrite: "2/5 = 144/x " ;
Cross multiply: 2x = 5(144) ;
Divide EACH SIDE of the equation by "2" ; to isolate "x" on one side of the equation; & to solve for "x" :

Answer: For #6, domain is {-3≤x<4}, range is {-3<y≤-1}
Step-by-step explanation: For #6 domain, the leftmost point on the graph is -3, with a closed circle. This means that x is greater than or equal to -3 (-3≤x). The rightmost point is 4, with an open circle, meaning that x is less than 4 (x<4). Put them together in the standard format, and you get {-3≤x<4}. Same principle for range; lowest point is -3, with an open circle (-3<y), and highest point is -1, with a closed circle (x≤-1). Result is {-3<y≤-1}.

O is the centre of the circle and ABC and EDC are rangers to the circle. Find the side of angle BCD. You must give reason in your answer. (4marks)PLZZZZZZ HELP!!
Answers
Every line from the tangent to the centre is 90°. This is said in the circle theorems.
So angle OBC and ODC are 90°.
angle O is twice the size of angle F. This is another circle theorem.
Therefore angle O is 152°.
The quadrilateral of ODBC would equal to 360°. Which means 90° + 90° + 152° = 332°
360° - 332° = 28°.
The answer is 28°
Answer:
∠BCD = 28°
Step-by-step explanation:
arc BD = 2 x inscribed angle ∠BFD = 2 x 76 = 152
arc BFE = 360 - arc BD = 360 - 152 = 208
tangent-tangent angle ∠BCD = (arc BFE - arc BD)/2 = (208 - 152)/2 = 28

Dilate the the triangle, scale factor = 3 (positive 3, ignore the
negative in the image below) with a center of dilation about
the origin.
A(-7,-6)
B(-5,-2)
C(-1,-5)
Answers
Answer:
The rule of dilation is [tex]P'(x,y) = 3\cdot P(x,y)[/tex].
The vertices of the dilated triangle are [tex]A'(x,y) = (-21, -18)[/tex], [tex]B'(x,y) = (-15,-10)[/tex] and [tex]C'(x,y) = (-3,-15)[/tex], respectively.
Step-by-step explanation:
From Linear Algebra, we define the dilation by the following definition:
[tex]P'(x,y) = O(x,y) + k\cdot[P(x,y)-O(x,y)][/tex] (1)
Where:
[tex]O(x,y)[/tex] - Center of dilation, dimensionless.
[tex]k[/tex] - Scale factor, dimensionless.
[tex]P(x,y)[/tex] - Original point, dimensionless.
[tex]P'(x,y)[/tex] - Dilated point, dimensionless.
If we know that [tex]O(x,y) = (0,0)[/tex], [tex]k = 3[/tex], [tex]A(x,y) = (-7,-6)[/tex], [tex]B(x,y) = (-5,-2)[/tex] and [tex]C(x,y) =(-1,-5)[/tex], then dilated points of triangle ABC are, respectively:
[tex]A'(x,y) = O(x,y) + k\cdot [A(x,y)-O(x,y)][/tex] (2)
[tex]A'(x,y) = (0,0) + 3\cdot [(-7,-6)-(0,0)][/tex]
[tex]A'(x,y) = (-21, -18)[/tex]
[tex]B'(x,y) = O(x,y) + k\cdot [B(x,y)-O(x,y)][/tex] (3)
[tex]B'(x,y) = (0,0) + 3\cdot [(-5,-2)-(0,0)][/tex]
[tex]B'(x,y) = (-15,-10)[/tex]
[tex]C'(x,y) = O(x,y) + k\cdot [C(x,y)-O(x,y)][/tex] (4)
[tex]C'(x,y) = (0,0) +3\cdot [(-1,-5)-(0,0)][/tex]
[tex]C'(x,y) = (-3,-15)[/tex]
The rule of dilation is:
[tex]P'(x,y) = 3\cdot P(x,y)[/tex] (5)
The vertices of the dilated triangle are [tex]A'(x,y) = (-21, -18)[/tex], [tex]B'(x,y) = (-15,-10)[/tex] and [tex]C'(x,y) = (-3,-15)[/tex], respectively.

what are the coordinates of the point on the directed line segment from (-4,10) to (2,-10) that partitions the segment into a ratio of 1 to 3
Answers
Answer:
(-5/2,5)
I hope it will be useful.
The coordinates of the point on the directed line segment that partitions the segment into a ratio of 1 to 3 is (1/2, -5).
What is the line segment?In geometry, a line segment is a part of a line that is bounded by two end points, and contains every point on the line that is between end points.
Now the given coordinates are,
(-4,10) and (2,-10)
Thus, we have,
x₁ = -4
y₁ = 10
x₂ = 2
y₂ = -10
Given ratio, m₁ : m₂ = 1 : 3
⇒ m₁ = 1; m₂ = 3
Let (x,y) be the coordinates of the point on the directed line segment from (-4,10) to (2,-10) that partitions the segment into a ratio of 1 to 3.
Since the section formula is given as,
So, x = (m₁x₁ + m₂x₂) / (m₁ + m₂)
y = (m₁y₁ + m₂y₂) / (m₁ + m₂)
Put the values,
x = [1(-4) + 3*2)] / (1 + 3) = (-4+6) / 4 = 2/4
⇒ x = 1/2
Similarly y = [1(10) + 3*(-10)] / (1 + 3) = (10-30) / 4 = -20/4
⇒ y = -5
So, the required coordinates are (1/2, -5)
Thus, the coordinates of the point on the directed line segment that partitions the segment into a ratio of 1 to 3 is (1/2, -5).

Complete Question
Mr. Nguyen bought a package of 3 chicken legs and a package of 7 chicken wings. Ms. Dawes bought a package of 3 chicken legs and a package of 6 chicken wings. Mr. Nguyen bought 45 ounces of chicken. Ms. Dawes bought 42 ounces of chicken. How much did each chicken leg and each chicken wing weigh?
Answer:
Weight of Chicken leg = x = 8 ounces
Weight of Chicken wing = y = 3 ounces
Step-by-step explanation:
Let us represent
Weight of Chicken leg = x
Weight of Chicken wing = y
Mr. Nguyen bought a package of 3 chicken legs and a package of 7 chicken wings.Mr. Nguyen bought 45 ounces of chicken.
3x + 7y = 45 ounces.... Equation 1
Ms. Dawes bought a package of 3 chicken legs and a package of 6 chicken wings. Ms. Dawes bought 42 ounces of chicken.
3x + 6y = 42 ounces... Equation 2
Combining both Equations together we solve by Elimination method
3x + 7y = 45.... Equation 1
3x + 6y = 42... Equation 2
We eliminate x by subtracting Equation 2 from Equation 1
Hence:
y = 3 ounces
Solving for x
3x + 6y = 42 ounces... Equation 2
3x +6(3) = 42 ounces
3x + 18 = 42 ounces
3x =( 42 - 18) ounces
3x = 24 ounces
x = 24 ounces/3
x = 8 ounces
Hence:
Weight of Chicken leg = x = 8 ounces
Weight of Chicken wing = y = 3 ounces
Answer:
chicken leg- 8 oz
chicken wing- 3 oz
