B is the midpoint of AC. If AB =x +5 and BC = 2x -11, find the measure of AB

1 answer:

8 0

If B is the midpoint of AC, that means the the line segments connecting the endpoints to the midpoints are the same length, or: AB = BC. With that in mind, we can set their lengths equal to each other:

x + 5 = 2x - 11

From there, simply solve for x and input that result back into the expression for AB (x + 5) and you’ll have your result.

Use the table to write a linear function that relates y to x.

Answer:

y = - $\frac{2}{3}$ x

Step-by-step explanation:

the equation of a linear function in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 8, 2) and (x₂, y₂ ) = (1, - 4) ← 2 ordered pairs from the table

m = $\frac{-4-2}{1-(-8)}$ = $\frac{-6}{1+8}$ = $\frac{-6}{9}$ = - $\frac{2}{3}$

the ordered pair (0, 0 ) indicates the line crosses through the origin, then

c = 0

y = - $\frac{2}{3}$ x + 0 , that is

y = - $\frac{2}{3}$ x ← equation of linear function

Given the linear equation 6x-2=2x+12, find x<br> HELPPP PLEASEEE ASAP!!! <br> Processss!

EleoNora [17]

Answer:

x=3.5

Step-by-step explanation:

add 2 to each side to cancel out the -2

6x=2x+14

subtract 2x from each side

4x=14

divide by 4

x=3.5
