1. self explanatory
2. self explanatory
3. 6*-5=-30 -30+83=53
4. put y as 28
28=-5x + 83 now solve for x
subtract 83 both sides
-55=-5x
divide -5 from both sides
11=x

Answer:
x = -1
Step-by-step explanation:
1.1 Pull out like factors :
-2x - 2 = -2 • (x + 1)
2.1 Solve : -2 = 0
x = -1
The first step for solving this is to cancel equal terms on both sides of the inequality.

< 0
Now multiply both sides of the inequality by -2 and flip the inequality sign.
-2 × (

) > -2 × 0
Remember that multiplying two negatives together always equals a positive,, so the expression changes to the following:
2 ×

> -2 × 0
Reduce the numbers with 2.
x > -2 × 0
Any expression multiplied by 0 equals 0,, so the correct answer to your question will be:
x > 0

Answer:
f(- 2) = 16
Step-by-step explanation:
Substitute x = - 2 into f(x), that is
f(- 2) = 5(- 2)² - 4 = 5(4) - 4 = 20 - 4 = 16
