Given:
To find:
The product of the expression.
Solution:
Take out -4 as a common factor in Last two terms.
Make sure the terms in both brackets must be same.
Take out common factor (2y - 5) from both terms.
4 can be written as 2².
Using the identity: 
.
The product is 
.
Answer:. .. ..
Step-by-step explanation:
Answer:
4/6
Step-by-step explanation: numerator is the top number and denominator is the bottom number so in this case 4 is the numerator and 6 is the denominator.
A) $2.30 more.
B) y=0.085x
C) A sample table is attached, listing the values for x, the process and the value for y.
ExplanationA) The amount of tax on a $12.99 book is given by 0.085(12.99)=1.10415≈$1.10.
The amount of tax on a $39.99 video game is given by 0.085(39.99)=3.39915≈$3.40.
This gives us a difference of 3.40-1.10 = $2.30.
B) Using x as the cost before tax and y for the amount of tax, we have the equation y=0.085x.
8.5% = 8.5/100 = 0.085. To find the amount of tax, we multiply this rate by the cost, which gives us the equation above.
Y=3x-2 put that value in the other equation
3x-2 = -2x + 3
Simplify
5x = 5
x = 1
Now take that value of x and put it in the other equation
y = -2(1) + 3
y = -2 + 3
y = 1 and x = 1
1 = 3(1) - 2 and 1 = -2(1) + 3
1 = 3-2 and 1 = -2 + 3
1 = 1 and 1 = 1
