Answer:

Step-by-step explanation:

f+t=40 and 4f+2t=100

4f+2t=100

2t=20

t=10

So f=20

If b is the midpoint of ac and ac = 8x-20, find bc

KengaRu [80]

Answer:

BC=4x-10

Step-by-step explanation:

B is the Mid point of AC . hence the length of BC will be half of AB

AC = 8x-20

Hence AB=BC = $\frac{8x-20}{2}$

BC=4x-10

Find the slope of the line that passes through the pair of points.<br> (11, 7), (−6, 2)

Anit [1.1K]

Answer:

Slope is 5/17.

Step-by-step explanation:

Subtract the y's and put on top of a fraction. Subtract the x's and put on the bottom of the fraction. Simplify. Be sure to start with the x and y that go together in front of the minus sign and end with the other x and y behind the minus sign.

7 - 2 put 5 on top.

11 - -6 is 17 (because 11 - -6 is the same as 11+6)

So you get 5/17 and it cannot be simplified so it is your answer.
