f(x)=\dfrac{4}{x}\qquad\qquad\qquad g(x)=\dfrac{4}{x}\\\\\\\\f(g(x))=f(\frac{4}{x})=\dfrac{4}{\frac{4}{x}}=4\cdot\dfrac{x}{4}=\boxed{x}\\\\\\\\ g(f(x))=g(\frac{4}{x})=\dfrac{4}{\frac{4}{x}}=4\cdot\dfrac{x}{4}=\boxed{x}

so f and g are inverses.

What is the answer for finding the slope from two points. Please help I am very confused
Nataly [62]
Slope = \frac{y2 - y1}{x2 - x1}
------------------
Substitute as followed
y2 = 4
y1 = 1/2
x2 = 1/2
x1 = 2
Slope = \frac{4- \frac{1}{2} }{ \frac{1}{2}-2}
--------------------------
Solve
4 - 1/2 = 7/2
1/2 - 2 = -3/2
\frac{7/2}{-3/2}
-7/3 = slope

Help with this question please
Tasya [4]
Let's simplify both sides to get:
7y+14 = 9+8y-2

Now we need to solve for y:
14 = 9+y-2
14 = 7+y
y = 7

So, your answer is A.

If a line passes through the points (-5,-4) and (3,-1), the equation of the line is?
Ratling [72]

answer: y = 1.5x - 5.5

explanation:

use y = mx +b to model your equation

(m = slope, b = y-intercept)

let's start by finding slope

to find slope, subtract the y values over the x values.

- 4 - (-1) / - 5 - (-3)

solve and simplify.

 -3 / -2

two negatives equals a positive, so convert into a decimal and remove the negative

you get 1.5.

now, plug the slope a y and x value into the equation to find b, the missing value.

-1 = 1.5(3) + b

-1 = 4.5 + b

-5.5= b

so, your equation is y = 1.5x - 5.5.
