Joe's mountain bike weighs 7 pounds more than Andy's. If there bikes weigh 45 pounds altogether, how much does Joe's bike weigh? Make sure to set up an equation.

Hint: Who is just X?

26

Step-by-step explanation:

45-7=38. 38/2=19. 19+7=26. 26+19=45

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

range is infinite on both x and y axis positive and negative
