Answer:
g= -2
Step-by-step explanation:
Answer:
- 2
Step-by-step explanation:
1. open the parentheses: 3(5-g)= 15-3g= 21
2. move variables and constants of different sides (signs change when a variable or constant moves to the other side of equal sign.)
15- 3g= 21 = -3g= 21- 15
-3g= 6
3. get g alone on 1 side: divide -3g by -3 so that the -3 cancel, then also divide 6 by 13 so that the equation will stay balanced.
Hence, g= -2

-7x+6y=34 7x+4y=-24 helppp
Answer:
x=–4, y=1
Step-by-step explanation:
adding the 2 equations, we see the X's go away and we are left with: 10y=10. we can simplify and solve for y by dividing both sides by 10 and we are left with y=1
plugging 'y=1' into the fist equation we get: -7x+6=34. we can now solve for x by subtracting 6 from both sides and dividing both side by –7, so we are left with: x=–4
we can check by plugging both x and y into one of the original equations:
-7(-4)+6(1)=34
28+6=34
34=34✓

1. Write the following statements in the from of equations.
a. One third of a number plus 7 is 26
Answer: The number is 57
Step-by-step explanation:
Lemme tell you , We dont know the number , so we imagine it as x
so the question says one third of a number , so 1 third is 1 divided by 3 and if we imagene the number as x , we can write x/3 .
So x/3 +7 = 26 , as the equation says one third of a number plus 7 is equal to 26.
So write the lcm of 3 and 7 and then cross multiply , and subtract . you get
x = 57 , and we imagined x as the number so if x is 57 , so the number we have to find is also 57 . Done Easy .
does the equation have roots? if yes, find them.
x^2=32
Answer:
[tex]x=\pm 4\sqrt2[/tex]
Step-by-step explanation:
Left hand side is a positive number. Right hand side is positive. The equation should have real roots. (worst case, the root would be complex, but let's not open that can of worm)
Let's start noticing that [tex]32 = 2^5 =4^2\cdot 2[/tex] and then take the square root of both sides, remembering that we need to take a plus or minus sign ( both a and -a squared give the same result!)
[tex]x= \pm \sqrt{4^2\cdot2}=\pm 4\sqrt2[/tex]

Write the equation of the parabola in vertex form. The vertex is (−3, 3) and the parabola passes through the point (4, 150). Create a rough sketch of the graph to use as a visual aid.
A.
y = 3(x + 3)^2 + 3
B.
y = 4(x − 3)^2 + 3
C.
y = 50(x + 3)^2 + 4
D.
y = 3(x − 3)^2 + 3
Answer:
A.
y = 3(x + 3)^2 + 3
Step-by-step explanation:
The vertex form of the equation is y=a(x-h)2 + k
You know that the vertex (h,k) is (-3,3) and a point on the parabola is (4,150). So what you’re needed ing to find is a bc all of the other letters can be replaced into the equation.
First I would put the equation into vertex form using the vertex given in the problem. : y= (x - (-3))2 + (3). Then I would use the ordered pair (4,150) and replace the x and y with those values
150 = a(4 + 3)2 + 3
Now simplify
150 = a (7)2 + 3
150 = 49a + 3 Important: please be sure to square.
147 = 49a
3= a
Next replace a into the formula now leaving x and y alone.
y = 3 (x+3)2 + 3 [Vertex form]
I hope this helps. Have a great day!
Answer:
A. [tex]y = 3(x + 3)^2 +3[/tex]
Step-by-step explanation:
The vertex form is:
[tex]y = a(x - h)^2 + k[/tex]
Where [tex]a[/tex] is the variable that determinate if the parabola is facing up or facing down and [tex]h[/tex] is the [tex]x[/tex] coordinate of the vertex and [tex]k[/tex] is the [tex]y[/tex] coordinate of the vertex.
So with the given values we have:
[tex]150 = a(4 + 3)^2 + 3[/tex]
Then isolate [tex]a[/tex] for find the missing value.
[tex]147 = a49\\\frac{147}{49} = a\\3 = a[/tex]
Then the final answer is [tex]y = 3(x + 3)^2 +3[/tex]

2. What does the ordered pair (1, 16) represent in this situation?
212
1234
078410
3. Describe how you know that this is a proportional relationship:
Answer:
Give me some hint please
The rate of change is 16, the equation is y = 16x, the (1,16) represents that the cost of 1 ticket is $16 and by y = 16x it is clear that it is a direct proportion.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
The table of tickets and their cost is given,
The graph of it has been plotted below,
The rate of change or slope = (48 - 32)/(3 - 2) = 16
The equation is y = mx + c where m is the slope and it is 16
So, y = 16x + c
Now substitute (2,32)
32 = 2(16) + c
c = 0
So the equation becomes y = 16x
Since y = kx is a direct proportional equation so it will be also direct proportionally.
In (1,6) , 1 = number of ticket , 16 = cost of ticket so it is $16.
Hence "The rate of change is 16, the equation is y = 16x, the (1,16) represents that the cost of 1 ticket is $16 and by y = 16x it is clear that it is a direct proportion".

Find the equation of the linear function represented by the table below in slope-intercept form.
x 0 1 2 3 4
y -8 0 8 16 24
Answer:
y = 8x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 8) and (x₂, y₂ ) = (2, 8) ← 2 ordered pairs from the table
m = [tex]\frac{8-(-8)}{2-0}[/tex] = [tex]\frac{8+8}{2}[/tex] = [tex]\frac{16}{2}[/tex] = 8
The line crosses the y- axis at (0, - 8 ) ⇒ c = - 8
y = 8x - 8

Janna is making a prediction of the frequency of a key that is 12 keys from middle C. A 2-column table with 5 rows. The first column is labeled number of keys above middle c with entries 0, 1, 2, 4, 8. The second column is labeled frequency (hertz) with entries 277. 18, 293. 66, 311. 13, 249. 23, 440. 0. Which best describes her prediction? interpolation, because a key that is 12 keys from middle C is within the data set interpolation, because a key that is 12 keys from middle C is outside the data set extrapolation, because a key that is 12 keys from middle C is within the data set extrapolation, because a key that is 12 keys from middle C is outside the data set.
Answer:
(d) extrapolation, because a key that is 12 keys from middle C is outside the data set
Step-by-step explanation:
Any prediction made outside the data set is called "extrapolation." The key 12-keys out is outside the domain 0–8 of the data set.

Teresa received a $90 gift card for a coffee store. She used it buying some coffee that cost $8.59 per pound. After buying the coffee, she had $38.46 left on her card. How many pounds of coffee did she buy?
Answer:
6 pounds of coffee
Step-by-step explanation:
Given Teresa's $90 gift card for a coffee store, and a balance of $38.46 on her card:
Subtract the remaining balance of $38.46 from the $90 original balance on Teresa's card, to determine how much she spent on coffee.
$90.00 - $38.46 = $51.54
Next, divide the amount that she spent at the coffee store by the $8.59 cost per pound to find out how many pounds of coffee she purchased from the store:
$51.54 ÷ $8.59 per pound = 6 pounds
Therefore, she bought 6 pounds of coffee worth $51.54 from the store.

the perimeter of an equilateral triangle is 14.4 cm. Find out the length of the side of that triangle in decimal fraction
Answer:
Side length = 4.80 cm
Step-by-step explanation:
Given the perimeter of an equilateral triangle, 14.4 cm:
An equilateral triangle has three congruent sides.
Since a triangle has three sides, and the sum of those sides represent the perimeter. We can assume that each side of the triangle represents a third (⅓) of the perimeter.Perimeter of an equilateral triangle = side + side + side = 3(side)
Perimeter = 14.4 cm
[tex]\displaystyle\mathsf{side=\frac{14.4\:cm}{3}=4.80\:cm}[/tex]
Therefore, the length of each side of an equilateral triangle is: 4.80 cm.
