Answer:
x=5,y=1 and z=-2
Step-by-step explanation:
We are given that system of equation
(I equation)
(II equation )
(III equation )
Equation II multiply by 3 then add with equation I
Then, we get
....(Equation IV)
Subtract equation II from equation III then we get
(equation V)
Adding equation IV and equation V then, we get

Substitute x=5 in equation V then, we get




Substitute x=5 and y=1 in equation then, we get




Hence, the solution for the given system of equation is given by
x=5,y=1 and z=-2
Answer: distributive property
Step-by-step explanation:



Answer:
y =5x
Step-by-step explanation:

(5 - 0) = m(1 - 0)
5 = m(1)
5 = m

y - 5 = 5(x - 1)
y - 5 = 5x - 5
y = 5x -5 + 5
y = 5x
Given:
The function f(x) describes the amount of money, in dollars, the club will earn for wrapping x presents.

To find:
The f(658).
Solution:
We have,

Substitute x=658 to find the value of f(658).


It means, the club will earn $1974 for wrapping 658 presents.
Therefore,
.
