Answer:
HOW SHOULD WE KNOW WE DONT HAVE ANY INFORMATION EXCEPT 75% AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Step-by-step explanation:
The value of x is 7 because 8/24 = 1/3 so find 1/3 of 21
The area of the dock is 20ft
Answer:
A and A
the equation of a parabola in vertex form is
y = a(x - h)² + k
where ( h, k ) are the coordinates of the vertex and a is a multiplier
y = - 2(x + 3)² + 2 is in this form
with vertex = ( - 3, 2)
To find the y-intercept let x = 0
y = - 2(3)² + 2 = - 18 + 2 = - 16
Similarly
y = - 2(x + 2)² + 2 is in vertex form
vertex = ( - 2 , 2)
x = 0 : y = - 2(2)² + 2 = - 8 + 2 = - 6 ← y- intercept
hope this helped
