Answer:

x = -7/5 and x = 9/8

Step-by-step explanation:

To solve this equation, set both parts of the "expression" equal to 0.

5x + 7 = 0

Subtract 7 from both sides.

5x = -7

Divide both sides by 5.

x = -7/5

8x - 9 = 0

Add 9 to both sides.

8x = 9

Divide both sides by 8.

x = 9/8

Which of the following is fartherest to the left on a number line 1/5, (0.1)to second power, 0.02

Alexxx [7]

1/5 is .2
.1^2 is .01
.02 is .02

So the furthest left would be the smallest number, which in this case is 0.1^2
