First take the exponent and 'kill' the 2, by - it from the 3, which gives you just 2x1 (Sorry can't make the one an exponent on this.). Then you take the 2x and times it by itself, so that you end up with 4x. Now you add the 4x and the 5x, to give you 9x. Then -5x from the 9x. to give us 4x again. Now you minus the 2. so that we have 4x-16 dived by x=? from there you dived 4x by 1x to give you 4x. Then you add the -16 over. so that you have 4x=16, then just dived 16 by 4. In the end x=4.

What is the slope of the line that passes through the points (10,5)and (15,20)
kupik [55]

Answer:

<h2>The answer is 3</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}  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(10,5)and (15,20)

The slope is

m =  \frac{20 - 5}{15 - 10}   =  \frac{15}{5}  = 3 \\

We have the final answer as

<h2>3</h2>

Hope this helps you
