Find the value of x
10
15
20
25

20

I hope this is right

Step-by-step explanation:

5x +12 + 3x + 8 =180

8x + 20= 180 ( subtract 20 )

8x= 160

X=20

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
