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
Answer:
If you are rounding to the nearest tens the smallest number is 45. If you are rounding to the nearest whole number, the smallest number is 49.5
Divide $4.20 by 2 to get how much $ a pound then multiply by 5 MAKE SURE TO DO IT TWICE in order to have the right answer
Answer:
265
Step-by-step explanation:
The computation of the amount that should be make out together is shown below:
Let us assume the number of hours be x
And, the total money earned be y
Now the equation would be
y = 6x + 43
= 6(37) + 43
= 265
Answer:
8x+12
Step-by-step explanation:
Remember that perimeter is all the sides combined. A rectangle has the same length and width for both sides.
P=2l+2w
P=2(4x-6)+2(12)
P=8x-12+24
P=8x+12
