Answer:

(1, -8)

Step-by-step explanation:

The transformation 4f(x) means the y-value is multiplied by 4, while the x-value stays the same.

... f(1) = -2

... 4f(1) = 4×(-2) = -8

... (1, -2) ⇒ (1, -8) . . . . vertical expansion by a factor of 4

Solve the inequality 3 -2a > 7

Paul [167]

3 - 2a > 7
We need to solve for a

First, let's subtract 3 on both sides to have the variables on a side and the numbers on another side:
3 - 2a > 7
3 - 2a - 3 > 7 - 3
- 2a > 4

Let's divide both sides by -2 to have a on side and its value on the other side:
-2a > 4
(-2a)/(-2) > (4/-2)
a < -2 (In a case of an inequality, we change the sign when we divide by a negative number to its opposite).

So 3 - 2a > 7 when a < -2 (answer c)

Hope this helps! :D
