HELP! What is AB? WILL GIVE BRAINLIEST!

Natalija [7]

AB = BC

3x-4=5x-10
-4=2x-10
6=2x
3=x

AB = 3x-4
AB = 3 (3)-4
AB = 9-4
AB =5

Therefore, AB is 5.

BC = 5x-10
BC = 5(3)-10
BC = 15-10
BC= 5

Miguel runs 6 miles in 55 minutes. At the same rate, how many miles would he run in 44 minutes

Karo-lina-s [1.5K]

You can write this in a proportion way: 6/55 = x/44.
Multiply both sides by 11 to get rid of the 55 and 44: 6/5 = x/4
Now, multiply both sides by 20: 5x = 24. x = 4.8

Therefore, he can run 4.8 miles in 44 minutes.

What’s the answer for the formula question

Luda [366]

Answer: N = 5

Step-by-step explanation:

M = 3N + 4R

M = 43

R = 7

Replacing by the values

43 = 3N + 4*7

43 = 3N + 28

43-28 = 3N

3N = 15

N = 15/3

N = 5

Which of the following point-slope form equations could be produced with the points (-1, 4) and (2, -3)?

Nikolay [14]

Answer:

Option B, y + 3 = -7/3(x - 2)

Step-by-step explanation:

Point slope form: (y - y1) = m(x - x1)

Step 1: Find the slope

m = $\frac{y2 - y1}{x2 - x1}$

m = $\frac{-3 - 4}{2 - (-1)}$

m = $\frac{-7}{2 + 1}$

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

Step 2: Plug into the point slope form

(y - 4) = -7/3(x - (-1))

(y - 4) = -7/3(x + 1)

(y - (-3)) = -7/3(x - 2)

y + 3 = -7/3(x - 2)

Answer: Option B, y + 3 = -7/3(x - 2)
