The answer is 26 because I said so I took this 5 years ago I’m in college now
Answer:
f(x) = 6x² - 24x + 21
Step-by-step explanation:
The equation of a quadratic function in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (2, - 3 ) , then
f(x) = a(x - 2)² - 3
To find a substitute (1, 3 ) into the equation
3 = 1(1 - 2)² - 3
3 = a(- 1)² - 3
3 = a - 3 ( add 3 to both sides )
6 = a
f(x) = 6(x - 2)² - 3 ← in vertex form
= 6(x² - 4x + 4) - 3
= 6x² - 24x + 24 - 3
f(x) = 6x² - 24x + 21 ← in standard form
U basically solve: (4sqrt8)*2 + (5 sqrt 12 + 6 sqrt 20)*2
for A)
if she has $ for the downpayment of $70
for B)
360-70+290
290/ 5=58
amount paid = 290-58(#month)
a=290-58m
ANSWER
A= -58m+290
