Evaluate the expression 2(a - 5) + 2, for a=15

This expression equals 22

Step-by-step explanation:

2(a-5)+2 a=15

2(15-5)+2

2(10)+2

20+2

=22

(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.
