Answer: w = -3u/2  +  2

Step-by-step explanation:

-12u + 13 = 8w - 3

Plzz help me! Choose the correct slope of the line that passes through the points (1, -3) and (3, -5).
ASHA 777 [7]

Answer:

<h2>The answer is - 1</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\

From the question the points are

(1, -3) and (3, -5)

The slope is

m =  \frac{ - 5 -  - 3}{3 - 1}  =  \frac{ - 5 + 3}{2}  =  -  \frac{2}{2}  =  - 1 \\

We have the final answer as

<h3>- 1</h3>

Hope this helps you

What is the inverse of the function? BRAINLIEST ANSWER WHOEVER ANSWERS FAST!!!!!!and it’s correct
vodomira [7]
First put a y in the place of f(x)
y = (1/3)^x
Then switch x and y
x = (1/3)^y
Solve for y
ln(x) = yln (1/3)
simplify
ln(x) = -ln(3)y
solve
y = -ln(x)/ln(3)
