Answer:
Explanation:
<em>The line y = -1 </em>is horizontal: parallel to the y-axis.
The point<em> B (2,3)</em> is above <em>the line y = - 1 </em>at a distance equal to the y-coordinate of B (y = 3) less - 1:
When the <em>point B (2,3) </em>is <em>reflected over the line y = -1</em>, the x-coordinate does not change. The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.
Hence,<em> the coordinates of the vertex B'</em> are x = 2, y = - 5: (2, - 5).
The first one is 90
The second one is 108
To make a fraction a percent, you have to divide the numerator by the denominator. You get a decimal. Multiply the decimal by 100 to get the percent or just move the decimal two places to the right.
So,
1.
Divide 1 by 5 and you get 0.20
Multiply 0.20 by 100. The answer is 20%
2.
Divide 2 by 3 and you get 0.6666.......
Multiply 0.6666..... by 100 and you get 66.6%
3.
Divide 1 by 40 and you get 0.025.
Multiply 0.025 by 100 and you get 2.5%
4.
Divide 4 by 8 and you get 0.5.
Divide 0.5 by 100 and you get 50%.
5.
Divide 12/16 and you get 0.75.
Multiply 0.75 by 100 and you get 75%.

Dealership A : 500 cash back , 5% tax
Becky : 15,000 + 0.05(15000) - 500 = 15,000 + 750 - 500 = 15,250
Michele : 20,000 + 0.05(20,000) - 500 = 20,000 + 1000 - 500 = 20500
dealership B : 1000 cash back, 8% tax
Becky : 15,000 + 0.08(15,000) - 1000 = 15000 + 1200 - 1000 = 15,200
Michele : 20,000 + 0.08(20,000) - 1000 = 20,000 + 1600 - 1000 = 20600
1. Becky will get the better deal at dealership B.....she saves 50 bucks
2. Michele will get the better deal at dealership A...she saves 100 bucks
3. ?....sorry
Done! 96 .... it's a cool one to think about
