Emily hires someone to walk her dog during the day. The cost for 2 walks is $9.00.

What is the cost for 5 walks?

2 walks is $9.00 so first i would find the unit rate

Step-by-step explanation: To find the unit rate you would have to get 2 to 1 which means we would have to divide it by 2. 2 / 1 is 1 then we also have to divide 9 by 2 which would get you 4.5. Now you know that 1 walk is $4.50 , but you need to know how much it coust for 5 so you multiply by 5.         $4.50 x 5 = $22.50

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

answer:

f(5/2) = 10/3

i hope this you!

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
