Answer:
me too a I don't understand
the answer for x is 76.4. the way to find it is by dividing 458.4 by 6 to find x s value.
11 square. units × 7 square. units × 1/2= B. 38.5 square. units.
Well, You divide both sides by -5.

Answer:
Step-by-step explanation:
hello :
an equation of this graph is : f(x) = a(x-h)²+k when (h,k) the vertex
so : h=5 and k= -4
f(x) = a(x-5)²-4....... now calculate : a
the y- intercept is : - 6.5 means : f(0) = - 6.5
put x=0 and f(x) = - 6.5
you have : -6.5 = a(0-5)²-4
-6.5 = 25a - 4
25a = -2.5 so : a= -2.5/25= 1/10
the equation is :
<h2>f(x) = (1/10)(x-5)²-4</h2>
