Plugging in the values, we get 7(6)-4=42-4=38.
Domain: 3<x<6
Range: 11<y<8
A and b are perpendicular meaning that they intersect forming 90
b and c are parallel meaning that the intersection of c and a is also perpendicular
11x - 9 = 90 degrees
solve
11x - 9 = 90
add 9 to both sides
11x = 99
divide both sides by 11
x = 9
Hope this helps
Answer:
Answer 3 (1.89m - 3)
Step-by-step explanation:
Since we know that the price per song is $1.89, that is going to be the part of the equation that goes with the variable.
Since she has a 3 dollar credit, this will reduce the cost of whatever amount of songs she is buying by 3 dollars, which means the second part of the equation is -3. You have your answer, 1.89m - 3.
Non taxable amount $ 49.35
Taxable amount $20.17
Tax amount $1.41
Total amount due $ 70.93
