Answer:
C
Step-by-step explanation:
Explanation is on picture.
Hope that helps :)
The given function is
f(x) = 8 x
Suppose , y = f(x) is function.
A vertical stretch by a factor of k means,
y = k f(x) , General formula for vertical stretch
Now the function is vertically stretched with a factor of 2.
Resulting function = g(x) = 2 f(x)= 2 × 8 x = 16 x,
Option (c) is right choice.
With u = <-7, 6> and v = <-4, 17>, we have
u + 3v = <-7, 6> + 3 <-4, 17> = <-7, 6> + <-12, 51> = <-19, 57>
We want to find a vector w such that
u + 3v + w = <1, 0>
Subtract u + 3v from both sides to get
w = <1, 0> - (u + 3v) = <1, 0> - <-19, 57>
w = <20, -57>
The store would earn 9.75$, because 3 bags of gerbil food is sold. Then you would multiply 3 by 3.25.

- n/6
- 0.70n
========================================================
Explanations:
- "4 more than p" means we add 4 onto p. For instance, let's say we replace p with 10. This means "4 more than 10" would be 4+p = 4+10 = 14.
- Not much to say here. We subtract the two items.
- The term "quotient" is the result of dividing two numbers. The slash / symbol means "divide" and it also is used for fractions.
- Skipping.
- Similar to problem 1, but now we subtract since the result is smaller than x. For instance, let's say x = 30. Then 23 less than this is x-23 = 30-23 = 7.
- If n is some number, then twice that is 2n. We add on 2 more to get 2n+2 as the answer.
- Same idea as problem 2. "A number" stands in place of "n".
- "Product" means "result of multiplication". So we multiply 5 and the number to say 5 times n = 5*n = 5n.
- Similar idea to problem 3, but we use "a number" in place of "n".
- We multiply the number of cans (n) with the price per can (0.70) to get 0.70n
