The value of a collectible coin can be represented by the equation y = 2 x + 15, where x represents its age in years and y represents its total value in dollars. What is the value of the coin after 19 years?

y = 53

Step-by-step explanation:

To get the answer, first put 19 in place of the x, and then times that iwth two, getting 38, you add that to 15. The answer is 53.

The Value of the coin after 19 years is $53.

Step-by-step explanation:If x=age, then simply substitute the x in “2x+15” for 19.After you do that you should get y=2(19)+15.Do the math to get y=38+15. Y=53.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
