Step-by-step explanation:
Given
per copy
Solving (a): Linear Equation
The total charges (y) is: the base charge + the rate * number of copies (x).
So, we have:
<em>The 0.44 is 44 cents converted to dollars</em>
Solving (b): Purchase if he budgets $76.16
This implies that y = 76.16
So, we have:
Collect like terms
Solve for x
Answer:
A.
Step-by-step explanation:
If
AND
y = x + 7, then by the transitive property of equality:
We can solve for the values of x by getting everything on one side of the equals sign and then solving for x:
We can factor out the common x to get:
x(x + 1) = 0
which tells us by the Zero Product Property that either
x = 0 and/or x + 1 = 0 and x = -1
We are expecting 2 solutions for x since this is a second degree polynomial. We will sub both -1 and 0 into y = x + 7 to solve for the corresponding values of y
y = 0 + 7 so
y = 7 and the coordinate is (0, 7)
y = -1 + 7 so
y = 6 and the coordinate is (-1, 6)
