Answer:
x= -1/4 and 8
Step-by-step explanation:
2x^2 - 8=31x -2x^2
Combine like terms and move all terms to one side:
4x^2-31x-8=0
use the quadratic formula.
(I can't type this out, but you just plug in the numbers into the formula which you can look up if you don't know it)

Step-by-step explanation:
<u>Step 1: Define</u>
-8x + 1 < 41
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 1 on both sides: -8x < 40
- Divide -8 on both sides: x > -5
Here we see that any value <em>x </em>greater than -5 would work as a solution to the inequality.
Answer:
x=50
Step-by-step explanation:
Since it's a straight line, 3x-20+x=180. 4x=200, x=50
