Answer:
y+8=-5(x-3)
Step-by-step explanation:
The formula for point-slope form is y-y1=m(x-x1)
The points for (x1, y1) are (3, -8), meaning that 3 is x1 and -8 is y1.
So, start by writing your equation like this: y--8=m(x-3)
For the equation y--8=m(x-3), the y--8 will change to a + sign because two negatives make a positive, right? So, the equation should now look like this: y+8=m(x-3).
We know that the slope (m) is -5. Plug that into the equation to get this: y+8=-5(x-3)
And there you have it!! The equation is now in point-slope form!!
y+8=-5(x-3) is the final answer!!
Hope that helps you!! Please give me brainliest!!

claire mixes 2 1/2 cups of water with 1/3 cup of orange juice concentrate. Han mixes 1 2/3 cups of water with 1/4 cup of orange juice concentrate. whose orange juice mixture tastes stronger? explain and show your reasoning
Answer:
Han's mixture tastes stronger, because...
Han's uses 6 2/3 cups of water for every 1 cup of orange juice concentrate.
Clare uses 7 1/2 cups of water for every 1 cup of orange juice concentrate.
Step-by-step explanation:
Claire
Cups of water = 2 1/2 cups
Cups of orange juice = 1/3
Cups of water for every cup of orange juice = 2 1/2 ÷ 1/3
= 5/2 × 3/1
= 15/2
= 7 1/2
Han:
Cups of water = 1 2/3 cups
Cups of orange juice = 1/4 cups
Cups of water for every cup of orange juice = 1 2/3 ÷ 1/4
= 5/3 × 4/1
= 20/3
= 6 2/3
Your search - construct a right triangle ABC in which base ABC in which baseBC =4.8cm,AngleB=90 degree and AC=6.2cm.
Answer:
AB = 3.9CM ; A = 51° ; C = 39°
Step-by-step explanation:
Base BC = 4.8cm
AC = 6.2cm
Angle B = 90°
Using trigonometry, the length of AB can be obtained thus :
AB^2 = AC^2 - BC^2
AB^2 = 6.2^2 - 4.8^2
AB^2 = 38.44 - 23.04
AB^2 = 15.4
AB = sqrt(15.4)
AB = 3.92 cm
Angle A :
Using :
Sinα = opposite / hypotenus
Sinα = 4.8 / 6.2
Sinα = 0.7741935
α = sin^-1 (0.7741935)
α = 50.73
A = 51° (approximately)
Angle C ;
(A + B + C) = 180 (Sum of angles in a triangle)
51 + 90 + C = 180
141 + C = 180
C = 180 - 141
C = 39°

On a coordinate plane, triangle A B C has points (negative 9, 3), (negative 9, 6), (0, 3) and triangle A double-prime B double-prime C double-prime has points (3, negative 1), (3, negative 2), and (0, negative 1). Which transformations could be performed to show that △ABC is similar to △A"B"C"? a reflection over the x-axis, then a dilation by a scale factor of 3 a reflection over the x-axis, then a dilation by a scale factor of One-third a 180° rotation about the origin, then a dilation by a scale factor of 3 a 180° rotation about the origin, then a dilation by a scale factor of One-third
Answer:
Option (4)
Step-by-step explanation:
Vertices of ΔABC are,
A → (-9, 3)
B → (-9, 6)
C → (0, 3)
If the given triangle is rotated 180° about the origin image triangle will have the vertices as,
Rule for the rotation,
(x, y) → (-x, -y)
A' → (9, -3)
B' → (9, -6)
C' → (0, -3)
If a point (x, y) is dilated by a scale factor of 'k',
Rule for the dilation,
(x, y) → (kx, ky)
Since, ΔA"B"C" is smaller than ΔABC,
Therefore, dilating ΔA'B'C' by a scale factor = [tex]\frac{1}{3}[/tex]
Image triangle ΔA"B"C" will be,
A" → (3, -1)
B" → (3, -2)
C" → (0, -1)
Therefore, Option (4) is the correct option.

John's Mathematics exam mark this year is increased by 5% to 84. Find his Mathematics exam mark
last year.
Answer:
80%
Step-by-step explanation:
Let's call the past exam mark m,
m*105%=84
m*105/100=84
m=84/(105/100)
m=80
Hope this helps!
Answer:
80
Step-by-step explanation:
new value = 84
old value = n
can use percent change formula: (new value - old value) / old value = 5/100
[tex]\frac{84-n}{n}[/tex] = [tex]\frac{5}{100}[/tex]
cross-multiply (you can simplify 5/100 to be 1/20 first): 20(84 - n) = n
1680 - 20n = n
1680 = 21n
n = 80

Answer:
1. The car is traveling at a constant speed 2. The car stopped 3. The speed is decreasing
Step-by-step explanation:
9514 1404 393
Answer:
constant speedstoppedslowingStep-by-step explanation:
You recall the relation between speed, distance, and time is ...
speed = distance / time
The graph is of distance vs. time. that means speed is the slope (distance/time) of the curve on the graph. If the slope is zero (a horizontal line), distance is not changing, and the speed is zero. That is, the vehicle has stopped.
If the slope is a positive constant, the vehicle is traveling at a constant speed.
If the slope is high, but becoming lower as the curve progresses left-to-right, then the speed starts high, but becomes lower: the vehicle is slowing down.
__
The graphs, left-to-right, represent a vehicle that is ...
traveling at constant speed
stopped

A student says that the sum difference, product and quotient of two
are always integers. Do you agree? Explain
Answer:
The quotient of two integers may not always be an integer.
Therefore, I do not agree when a student says that the sum difference, product, and quotient of two are always integers.
Step-by-step explanation:
The student is not largely correct!
The sum, difference, and product of two integers is indeed always an integer.
But, the quotient of two integers may not always be an integer.
For example, the quotient of integers 4 and 2 will be an integer.i.e.
4/2 = 2
But, if we take the quotient of 2 and 3, the result will not be an integer.i.e.
2/3 = 0.67
Therefore, I do not agree when a student says that the sum difference, product, and quotient of two are always integers.

Answer:
y=1/4x−6
Step-by-step explanation:
Write in slope-intercept form, y = m x + b .
Answer: y = 1/4x + 6
Step-by-step explanation:
12y -3x = 72 Add 3x to both sides

What is the distance formula?
The as-served cost of a kid's dinner special is $2.25. If the restaurant uses a target cost percentage of 35%, what is the target price of the kid's dinner special?
Answer:
$3.0375
Step-by-step explanation:
Original price of dinner = $2.25
If cost percentage of 35%, then the additional cost paid will be;
35% * 2.25
= 0.35 * 2.25
= $0.7875
Target price = Original price + additional cost
Target price = $2.25 + $0.7875
Target price = $3.0375
Which of the follwing is true 3 3/9+7 6/11=10 87/99 2 3/8+6 4/5=8 12/40 ,3 3/7+4 2/3=7 2/21 4 5/6+5 5/7=9 10/13
Answer: 3 3/9+7 6/11 = 10 87/99
Step-by-step explanation:
a. 3 3/9+7 6/11 = 10 87/99
First and foremost, we need to know the lowest common multiple of 9 and 11 which is 99.
Therefore, 3 3/9 + 7 6/11 would be:
= 3 33/99 + 7 54/99
= 10 87/99
This is correct
b. 2 3/8 + 6 4/5 = 8 12/40
First and foremost, we need to know the lowest common multiple of 8 and 5 which is 40.
Therefore, 2 3/8 + 6 4/5 would be:
= 2 15/40 + 6 32/40
= 8 47/40
= 9 7/40
Since the answer gotten is 8 12/40. This is wrong.
c. 3 3/7 + 4 2/3 = 7 2/21
First and foremost, we need to know the lowest common multiple of 7 and 3 which is 21.
Therefore, 3 3/7 + 4 2/3 would be:
= 3 9/21 + 4 14/21
= 7 23/21
= 8 2/21
Since the answer gotten is 7 2/21. This is wrong.
d. 4 5/6 + 5 5/7 = 9 10/13
First and foremost, we need to know the lowest common multiple of 6 and 7 which is 42.
Therefore, 4 5/6 + 5 5/7 would be:
= 4 35/42 + 5 30/42
= 9 65/42
= 10 23/42
This is wrong as the answer gotten is 9 10/13
Therefore, the true option is
3 3/9+7 6/11 = 10 87/99
A large cube has a volume of 1 cubic unit. A small cube has a volume of 1 27 of a cubic unit. What is the difference between the edge length of the large cube and the edge length of the small cube?
Given:
Volume of Large cube = 1 cubic unit
Volume of small cube = [tex]\dfrac{1}{27}[/tex] cubic unit
To find:
The difference between the edge length of the large cube and the edge length of the small cube.
Solution:
Let the edges of large and small cubes are [tex]a_1[/tex] and [tex]a_2[/tex] respectively.
We know that, volume of a cube is
[tex]V=(edge)^3[/tex]
Volume of Large cube = 1 cubic unit
[tex](a_1)^3=1[/tex]
Taking cube root on both sides, we get
[tex]a_1=1[/tex]
So, edge of large cube is 1 unit.
Volume of small cube = [tex]\dfrac{1}{27}[/tex] cubic unit
[tex](a_2)^3=\dfrac{1}{27}[/tex]
Taking cube root on both sides, we get
[tex]a_2=\dfrac{1}{3}[/tex]
So, edge of large cube is [tex]\dfrac{1}{3}[/tex] unit.
Now, difference between them is
[tex]d=a_1-a-2[/tex]
[tex]d=1-\dfrac{1}{3}[/tex]
[tex]d=\dfrac{3-1}{3}[/tex]
[tex]d=\dfrac{2}{3}[/tex]
Therefore, the difference between the edge length of the large cube and the edge length of the small cube is [tex]\dfrac{2}{3}[/tex] unit.
