Answer:

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

Step-by-step explanation:

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 \ -)

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

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

A group of kids do a car wash. They charge $4.50 for each small car they wash and eight dollars for each large car or SUV in the
Basile [38]

Answer:

Step-by-step explanation:

Let x and y represent the numbers of small and large cars washed, respectively.

We know that:

$4.50x + $8y = $420

But we don't know the relationship between x and y.  We need more information (e.g., they washed twice as many small cars and large).  Otherwise we have one equation and two unknowns.  Since there are two unknowns, we can't determine a "slope" of the line.  With all the water and soap, the most we could possibly say it will be a slippery slope.

Shelby, Allen, and Denise printed their digital photos. Each requested the same size prints. Shelby paid $2.70 for 5 prints. All
tekilochka [14]
Person:    Number of prints      Total Cost
Shelby             5                               2.70
Allen               11                              3.24
Denise            20                             4.05

To solve for the variable cost:
11 - 5 = 6
3.24 - 2.70 = 0.54
0.54 / 6 = 0.09 per print

To solve for the fixed cost
0.09 x 5 = 0.45
2.70 - 0.45 = 2.25 

y = 2.25 + 0.09x

y = 2.25 + 0.09(5) = 2.25 + 0.45 = 2.70
y = 2.25 + 0.09(11) = 2.25 + 0.99 = 3.24
y = 2.25 + 0.09(20) = 2.25 + 1.8 = 4.05
