Write an equation for the following transformation of y=x: a vertical stretch by a factor of 6.

A. y=6x
B.y=x/6
C.y=x+6
D.y=x-6
my answer is a

Thank you! Here are the rest of the answers for the quiz (answers may be different cause I'm in honors)

1) C. 8; $8 is put away each week

2) A. f(x+1)

3) A. g(x) = -x² - 5

4) D. The graph of g(x) is the graph of f(x) stretched vertically by a factor of 5 and translated up 5 units

5) A (The graph with the upside down V from (0,5)

6) B (The graph with the shaded part on the right side, and intersect at (-2,0) & (0,-2)

7) D. 5x - 6y ≥ -30

8) A. y = 6x

9) B. The graph of g is the graph of f translated to the left 3 units and down 7 unit.

I'll post the essay questions after a little bit!

Okay the first one is plain and simple!

First, multiply 30 hours by 60, because there are 60 minute in an hour. And you get 1800! It's obvious on what to do next. Just fill everything in!
15x + 30y ≤ 1800
^^

Now the second one!
First of all you gotta find the slope, so put that things into coordinates
(4.5, 1445) and (7, 2320)
So to find the slope,
(2320-1445)/(7-4.5) = 875/2.5
That equals 350

Now use substitution in the y = mx + b
x being 7 or 4.5, y being 2320 or 1445, and m being 350
I used (4.5, 1445)
1445 = 350 (4.5) + b
Multiply 350 and 4.5
1445 = 1575 + b
Subtract 1445 with 1575
-130 = b

So now you've got s = 350t - 130

Now you have to substitute t with 11.
s = 350(11) - 130
Multiply 350 and 11
s = 3850 - 130
Subtract
s = 3720

So the answer is 3720lbs of strawberries can be processed in 11hrs.

thank you

A is the correct answer.

Is it y=6x?

shift left 4 units and up 1 unit

Your answer is correct! The equation for a vertical stretch by a factor of 6 on the graph of y=x is y=6x. This means that each y-coordinate of a point on the original graph is multiplied by 6 to obtain the corresponding point on the transformed graph.
