Answer:

The slope is -3/7 so B

Step-by-step explanation:

Just turn this into slope-intercept form.

what you do is subtract 3x so that it's moved to the right side.

It should look like this -7y = 12 - 3x

Then just divide all numbers by 7 so everything is simplified

It should look like this y = -3/7x - 12/7

pls mark brainliest because i didn't waste you time lol

Is (-3, 2) a solution of -4r - 10y< - 9?

Blizzard [7]

Answer:

The point (-3,2) is not a solution of the inequality

Step-by-step explanation:

Inequality

Inequalities relate the left and the right side of an expression with an operator other than the equal sign.

The inequality given in the question is

$-4r - 10y< - 9$

There are many combinations of r and y that make inequality be true. For example, for r=1 and y=1

$-4(1) - 10(1)< - 9$

$-14< - 9$

This relation is true since -14 is less than -9.

Also, there are many combinations that make the given inequality be false.

For example, for r=2 and y=-1

$-4(2) - 10(-1)< - 9$

$-8+10$

$2$

This inequality is false.

Let's test the point (-3,2)

$-4(-3) - 10(2)< - 9$

$12-10$

$2$

Which is false, thus the point (-3,2) is not a solution of the inequality

Given

The highest temperature recorded is $18^{\circ}$

The lowest temperature recorded is $-7^{\circ}$

The amount of change between the high and the low temperatures is

$\Rightarrow 18-(-7)=18+7\\\Rightarrow 25^{\circ}$
