Answer:
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
6 pies, 8 people
6 pies divided by 8 people
so 6/8
that is 0.75 or 3/4 or 75%
Answer:
(2x-3)(2x+1)
Step-by-step explanation:
4x^2 - 4x - 3
we need two numbers that give 12 when multiplied and 4 when subtracted
the numbers are 6 and 2 because 6*2=12 and 6-4=4.
4x^2 - (6-2)x -3
4x^2 -6x +2x -3
take common
2x(2x -3)+1(2x-3)
take (2x-3) as common
(2x-3)(2x*1 + 1*1)
(2x-3)(2x+1)
I have the answer in this picture. But im not sure if this might be really what your asking for.
D: 89 is the prime number.
