**Answer:**

- 1

**Step-by-step explanation:**

The equation of a line in slope- intercept form is

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

y = - x - ← is in slope- intercept form

with slope m = - 1

Parallel lines have equal slopes

Thus the slope of line d is - 1

Answer: I think it would be 112.

Step-by-step explanation:

1) x+23=2x+8

x-2x= 8-23

-x = -15

x=15

2)x+23=2x+8

x-2x=8-23

x= 15

WU= UW= x+23=15+23= 38

3)UV=UW+WV

UV= x+23 + 2x+8

UV=15+23+2*15+8

UV=38+38

UV=76

4) YA=YZ+ ZA

YA= x+12 +6x -13

YA=7x -1

x=15

YA=7*15-1

YA=105-1

YA=104

3a^2 * 2a^3 = 6a^5

because 3 x 2 = 6.....and a^2 * a^3 = a^(2 + 3) = a^5

put it all together and u get 6a^5
