An equation has an infinite number of solutions if the left and right sides are identical. Let's simplify them both and then decide the value of ?.
Left hand side:

Right hand side:

So, both sides have a numeric part of -20. We can use the "?" value to make sure that the literal part is the same as well. So, we want

Answer:
- 9x² + 10x + 4
Step-by-step explanation:
Calculate the subtraction as
- 4x² + 2x - 8 - (5x² - 8x - 12 ) ← distribute parenthesis by - 1
= - 4x² + 2x - 8 - 5x² + 8x + 12 ← collect like terms
= - 9x² + 10x + 4
Answer:
Slope: 9/10
Step-by-step explanation:
We need to find the slope of the line that passes through the coordinates given.
To find the slope, we would use the slope formula: m = y2-y1/x2-x1
Plug in your coordinates and solve:
m = 4-(-5)/4-(-6)
m = 4+5/4+6
m = 9/10
Since we can't simplify further, the slope of the line would be 9/10.
Y=3/4x-3 because none of the others make sense
