Answer:

d 13

Step-by-step explanation:

Subtracting means adding the opposite.

To subtract -4, you add the opposite of -4 which is 4, so you add 4.

9 - (-4) = 9 + 4 = 13

Christian wants to make an A in his class. There are 5 exams this year, and he has taken 4 of them. His grades were 84, 88, 95,

ioda

Answer:

last test grade=x x ≥ 79 so 79%

Step-by-step explanation:

(84/5)+(88/5)+(95/5)+(104/5)+(x/5) ≥ 90

Simplify: (371/5)+(x/5) ≥ 90

Subtract (371/5) from both sides

Then you have (x/5) ≥ (79/5)

Then multiply both sides by 5 and you have x ≥ 79

Given a graph for the transformation of f(x)=f(kx), determine the k value

jarptica [38.1K]

Answer:

B. k = 1/3

Step-by-step explanation:

Compare any two points on same horizontal line.

The easy one is:

f(-3) = g(-1) = - 3

Since g(x) = f(kx), substitute the x- coordinates to find the value of k:

- 1 = k*(-3)
k = - 1/ - 3
k = 1/3

Correct choice is B
