Answer:

r=-3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4r−3=3(3r+4)

4r+−3=(3)(3r)+(3)(4)(Distribute)

4r+−3=9r+12

4r−3=9r+12

Step 2: Subtract 9r from both sides.

4r−3−9r=9r+12−9r

−5r−3=12

Step 3: Add 3 to both sides.

−5r−3+3=12+3

−5r=15

Step 4: Divide both sides by -5.

−5r

−5

What is the slope of o line that passes through (-4,-14) and (19,11)?

DerKrebs [107]

Answer:

D, see description below.

There is a possible typo in the problem since these points have slope 25/23.

Step-by-step explanation:

To find the slope of a line, calculate the distance between points with a ratio of vertical to horizontal distance. This is done using the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Here the points are (-4,-14) and (19,11). Substitute and simplify.

$m=\frac{11--14}{19--4}=\frac{11+14}{19+4}=\frac{25}{23}$

I think there is a typo in your points (-4,-14) and (19,11) because the answer doesn't align to the answer choices. But based on them, I would answer D or 24/23 since it's the closest value.
