The trestle meets the ground at __ units and __ units

The answer to this for the first box is 0.9 and the second box 9.1

0.9 and 9.1

Step-by-step explanation:

The quadratic function y = -x2 + 10x - 8 models the height of a trestle on a bridge. The x-axis represents ground level.

To find where the section of the bridge meets ground level, solve 0 = -x2 + 10x - 8.

Where does this section of the bridge meet ground level?

Choose an equation that would be used to solve  0 = -x2 + 10x – 8

(x + 25)2 = –8

(x – 5)2 = 17  (This is the correct choice for the first part of the question.)

(x – 10)2 = 25

Solve the equation to find where the trestle meets ground level. Enter your answers from least to greatest and round to the nearest tenth.

The trestle meets the ground at  

.9

units and  

9.1

units.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range
