Simplify the variable expression by evaluating it's numerical part m-13+42-6

goldfiish [28.3K]

ANSWER

$m + 23$

EXPLANATION

The given expression is

$m - 13 + 42 - 6$

We regroup the numerical parts to get;

$m + 42 - 6 - 13$

Now let us simplify the negative numbers.

$m + 42 - 19$

We now subtract 19 from 42 to get;

$m + 23$

We can't simplify further

Hence the simplest form is:

$m + 23$

2. A line has an x-intercept of 2 and a y-intercept of 5. What is the slope of the line?

Blizzard [7]

Answer:

-5/2

Step-by-step explanation:

Use slope formula:

Given 2 points (x1, y1) and (x2, y2) Slope is

y2-y1/x2-x1

The x intercept is 2, the point would be (2,0)

The y intercept is 5, the point would be (0,5)

So you can do (5-0)/(0-2) which is 5/-2 which then would be -5/2
