Answer:
y = -(x+4)² +7
Step-by-step explanation:
I find it convenient to factor the leading minus sign from the first two terms, then work with what's left.
... y = -(x² +8x) -9
Now, add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.
... y = -(x² +8x +4²) -9 +4²
... y = -(x +4)² +7 . . . . . . . . . rewrite parentheses as a square; collect terms
He pays $223.65.
This is because from the equation you know that he pays 29.95+2.00 for one light therefore, if we use x to represent the amount of lights--
X(29.95+2.00)
is an equation you can use to solve for the amount Mr. Davis payed for his lights.
Answer:
b=130°
Step-by-step explanation:
The relationship between these two angles is about the fact that they are supplementary
i.e their sum is 180°
I'm unsure of the question but this expression can be written as:
16 + x < 32.
This can be simplified to:
x < 16
Turn 5% into a decimal which is 0.05, then multiply by 2.95 = 0.1475
round it off, which is 0.15
so $0.15 is the tax and if ur looking for the total price then add $2.95 to $0.15
