We need to apply distributive property on each of the given expressions to write their equivalent expressions.

(1)  -3(2x-4)

Upon using distributive property, we get:

(-3)(2x)+(-3)(-4)\\
-6x+12

(2) 0.1(-90+50a)

Upon using distributive property, we get:

-9+5a

(3) -7(+50a)

This part is incomplete.

(4) \frac{4}{5}(10y+-x+-15)

Upon using distributive property, we get:

\frac{4}{5}(10y)+\frac{4}{5}(-x)+\frac{4}{5}(-15)\\
8y-\frac{4x}{5}-12

Ostrovityanka [42]

Answer:

4/11

Step-by-step explanation:

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 1 - -3)/(7 - -4)

     = (1+3)/(7+4)

    = 4/11
