THE CORRECT ANSWER IS THE LAST ONE sorry caps :) hops this help tho plzz mark as best plzzzzzzzzzzzzzzz
A^2-8a-48=0
factor
(a+4)(a-12)=0
set each equal to 0
a+4=0 a-12=0
a=-4,12
Reflecting a point on the x axis is the same as performing the following transformation:
T -> (x, -y)
Applying the transformation we have
P (-3.2) ---> (x, -y) ----> p (-3, -2)
Therefore, the new point is
p (-3, -2)
answer
p (-3, -2)
Answer:
a = 2, b = - 3, c = - 8
Step-by-step explanation:
Expand f(x) = a(x + b)² + c and compare coefficients of like terms, that is
a(x + b)² + c ← expand (x + b)² using FOIL
= a(x² + 2bx + b²) + c ← distribute parenthesis by a
= ax² + 2abx + ab² + c
Compare like terms with f(x) = 2x² - 12x + 10
Compare coefficients x² term
a = 2
Compare coefficients of x- term
2ab = - 12, substitute a = 2
2(2)b = - 12
4b = - 12 ( divide both sides by 4 )
b = - 3
Compare constant term
ab² + c = 10 , substitute a = 2, b = - 3
2(- 3)² + c = 10
18 + c = 10 ( subtract 18 from both sides )
c = - 8
Then a = 2, b = - 3, c = - 8
81 houses total.
of 81 (27) sold last month.
81 - 27 = 54 houses remaining.
of 54 (36) sold this month.
54 - 36 = 18 houses remaining.
There are 18 houses left to be sold.
