Add alike terms. Basically you add stuff together with the same variable! Since -8y and +3y have a y variable, they can be added together. Same with x.

-8y + 3y = -5y. This is because you’re adding 3 from a negative number.

5x - 9x = -4x. You’re subtracting 9 from a positive number.

That is as simple as it can get, so you put those two numbers in the same equation.

The simplest expression is:

-5y - 4x

Answer: −4x−5y

Step-by-step explanation:

−8y+5x+3y−9x

=−8y+5x+3y+−9x

Combine Like Terms:

=−8y+5x+3y+−9x

=(5x+−9x)+(−8y+3y)

=−4x+−5y

−4x−5y

Find the slope easy giving brainlest

Korvikt [17]

Answer:

Problem 20: $m$ = $2$

Problem 21: $m$ = $-2$

Problem 22: $m$ = $1$

Problem 23: $m$ = $3$

Step-by-step explanation:

The formula to find the slope of a line: $m = \frac{y_{2} - y_{1}}{x_{2}-x_{1}}$ .

Problem 20:

1) Substitute the values into the formula and solve it.

$m$ = $\frac{3-7}{2-4}$

$m$ = $\frac{-4}{-2}$

$m$ = $2$

Problem 21:

1) Substitute the values into the formula and solve it.

$m$ = $\frac{-5-1}{2--1}$

$m$ = $\frac{-6}{3}$

$m$ = $-2$

Problem 22:

1) Substitute the values into the formula and solve it.

$m$ = $\frac{3-7}{-6--2}$

$m$ = $\frac{-4}{-4}$

$m$ = $1$

Problem 23:

1) Substitute the values into the formula and solve it.

$m$ = $\frac{-4-2}{-4--2}$

$m$ = $\frac{-6}{-2}$

$m$ = $3$

*Extra*: The equation of a line is written in this form: $y = mx+b$ , where $m$ is the slope and $b$ is $y$ -intercept

To increase an amount by 85% what single multiplier would you use

koban [17]

You could use 1.85 as a scalar, because that keeps the initial value and adds 85% of it.

An is a mathematical statement that shows two expressions are equal using an equal sign.

maksim [4K]

No! Because a mathematical statement is actually a statement that is either true or false not a statement that shows two expressions are equal using an equal sign!
