Answer:
x=3 & y=162
Step-by-step explanation:
it may help you
Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20
I'm not usually good at these questions but you can get a calculator that does weight multiplied by units.
so with your question it would be :
1.2 ounces x (48 units)
= 57.6 ounces
57.6 ounces
B - 8x
To find this, combine like terms.
8x - 2x is 6x, then add the two x's on the side to bring it back to 8x.
Hope this helps!
