Answer:
x = -4 or 2
Step-by-step explanation:
-4x² + 10x − 40 = -9x²
First, move the x terms to one side and the constant to the other.
5x² + 10x = 40
Divide by the leading coefficient:
x² + 2x = 8
Take half of the b coefficient, square it, then add to both sides.
(2/2)² = 1
x² + 2x + 1 = 8 + 1
x² + 2x + 1 = 9
Factor the perfect square:
(x + 1)² = 9
Solve for x:
x + 1 = ±3
x = -1 ± 3
x = -4 or 2
Answer:
Well if she is paying $126.00 and $108.83/month, she would be paying $1305.96 for the year and then add the $126.00 to it for the money she paid down for it making it $1431.96 for the entire year. BRAINLIEST ANSWER PLZZ!!
Step-by-step explanation:
a) 247 ÷ 11 = 22 r.5 <em>since there is a remainder it is not a factor</em>
b) 247 ÷ 13 = 19 there is no remainder so this is a factor! The other factor is 19.
Answer: B, D
yes, it does not matter if the y is at the beginning or at the end. However, most teachers usually prefer to have the y at the beginning as it is easier to read.
