Answer:
69
Step-by-step explanation:
69
Slope =

------------------
Substitute as followed
y2 = 4
y1 = 1/2
x2 = 1/2
x1 = 2
Slope =

--------------------------
Solve
4 - 1/2 = 7/2
1/2 - 2 = -3/2
-7/3 = slope
Answer:
It would be C, 64.387
Step-by-step explanation:
First, you have to solve 7x1/1000. This equal to 7/1000 which should be converted into decimal form (since all the answers are in decimal form). 7/1000 is 0.007 in decimal form.
It is 0.007 since in 7/1000, the denominator is 1000, making 7 in the thousandths place (the 3rd digit to the right of the decimal point).
The only number that contains 0.007 is the 3rd one, making it your answer.
Only 19 is a function because a function only has one y value for every x value. For the other graphs, there are at least two y values for each x value.
Answer:
f[g(x)] = 4x²+1/16
Step-by-step explanation:
We need to put g(x) into f(x).
f[g(x)] = 1/(1/2x+4)²
f[g(x)] = 1/(1/4x²+16) Solve the exponential.
f[g(x)] = 1/(1/4x²+16) Simply the fraction.
f[g(x)] = 4x²+1/16
