Answer:
Move all terms containing y to the left, all other terms to the right
<u>Add -14y to each side of the equation</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: 5y + -14y = -9y
</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: 14y + -14y = 0
</u>
<u></u><u></u>
<u></u>
<u>Add '20' to each side of the equation</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: -20 + 20 = 0
</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: 7 + 20 = 27
</u>
<u></u><u></u>
<u></u>
<u>Divide each side by -9</u>
<u></u><u></u>
Answer:
695
Step-by-step explanation:
X^2-x-11=-x-7
X^2-11=-7
X^2=4
X=2 (4 was reduced to 2 after the equation was square rooted)
Pls give brainliest so close to ranking up
two points are (0,0) and (100, -800)
m = (y2-y1)/(x2-x1) = (-800-0)/(100-0) = -8
point slope form of the line is
y-y1 = m(x-x1)
y-0 = -8 (x-0)
y=-8x
this is in slope intercept form now
y=-8x
