3 times 7.75 = 23.25 + 7.75 = 31.00
so the basketball is $23.25 and the pump is $7.75
Answer: f-1(y) = (y-3)/2
Step-by-step explanation:
f(x) = 2x+3, written as a flow diagram:
2x+3
The Inverse Function goes the other way:
Inverse
So the inverse of: 2x+3 is: (y-3)/2
The inverse is usually shown by putting a little "-1" after the function name, like this:
f-1(y)
We say "f inverse of y"
So, the inverse of f(x) = 2x+3 is written:
f-1(y) = (y-3)/2
Answer:
(6)7+
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Find the mean
9+12+10+15+15+15+10+x/8=12
divide 86+x/8=12
multiply both sides by 8
86+x=96
sub 86 from both sides
x=10
hope this helps
The general form for this is y^2 = 4ax where a = focus
the directrix is same distabce behind the vertex as focus is in font so focus a = 4
so we have y^2 = 16 x
or
x = (1/16) y^2
Its C
