Answer:

-1 $\frac{7}{8}$

Step-by-step explanation:

4x-8y=15

4x-8y-4x=15-4x

-8y=15-4x

-8y/-8=15-4x/-8

y=-1 7/8+1/2x

slope is -1 7/8

Answer:

$t = \frac{2-3q}{q+4}$

Step-by-step explanation:

$q = \frac{2-4t}{t+3}\\\\$

Cross multiply,

q(t+3) = 2 - 4t

Use distributive property: a*(b + c) =(a*b) + (a*c)

qt + 3q = 2- 4t

qt + 4t + 3q = 2

qt + 4t = 2 - 3q

t(q + 4) = 2 -3q

$t = \frac{2-3q}{q+4}$

Answer:

m<BCA+m<BCD=180

Step-by-step explanation:

supplementary means that the angle measures add up to 180°, if you are using the definition of supplementary angles AND you have had a statement saying that two angles are supplementary, ALWAYS follow it with the sum of the measures of those angles equal 180 :)
