Both equal to y so set equal to each other
4x+4=x²+4
minus 4 both sides
4x=x²
minus 4x both sides
0=x²-4x
factor
0=x(x-4)
set each to zero
0=x
0=x-4
4=x
x=4 and 0

Amount of hours worked = h
7h = 91
h = 13 hours worked that week
h (is greater to or equal to) 15
7 x 15 would equal 105 which means the most she can make in a week is $105

Answer:
<em><u>x=−2</u></em> if i could get brainliest that would be great
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(−x+2x+1)=x−1
(3)(−x)+(3)(2x)+(3)(1)=x+−1(Distribute)
−3x+6x+3=x+−1
(−3x+6x)+(3)=x−1(Combine Like Terms)
3x+3=x−1
3x+3=x−1
Step 2: Subtract x from both sides.
3x+3−x=x−1−x
2x+3=−1
Step 3: Subtract 3 from both sides.
2x+3−3=−1−3
2x=−4
Step 4: Divide both sides by 2.
2x/2=−4/2
x=−2
