Pavel [41]

Answer:

Step-by-step explanation:

Let x represents the amount that the customer pays per hour

for renting the vacuum cleaner before returning it.

Let y represent the flat rate that the store charges a customer for renting the vacuum cleaner.

Let F represent the amount that the store charges a customer for renting the vacuum cleaner for x hours.

A linear function F for the total retail cost of a vacuum cleaner would be

F(x) = x + y

If the customer rents it for n hours, the total amount becomes

F(x) = nx + y

kirill115 [55]

Answer:

Joe would receive $9.10 for One hour of mowing the lawn and $39.50 for Five hours of babysitting, which (if needed) adds up to $48.60

Could someone please help me with this problem
lina2011 [118]

Answer:

a = -1 , b = 4 , c = 3 , d = 1

Step-by-step explanation:

Given:

(-xy)^3 (xz) =ax^by^cz^d

The right hand side = (-xy)³ (xz) = (-1)³ x³ y³ x z = (-1) x⁴ y³ z

Comparing the right hand side with the left hand side

∴ a = -1

∴ b = 4

∴ c = 3

∴ d = 1

=======================================

The general rules of exponent:

1) \ a^m * a^n = a^{m+n}\\2) \ a^m / a^n = a^{m-n}\\3) (-1)^m = 1 \ (if \ m \ is \ +) and \ = \ -1 \ (if \ m \ is \ -)
