The only solution is when y=y
x+1=x-1 subtract x from both sides
1=-1
This is never true so there are no solutions. In this case it is due to the fact that both lines have the same slope and different y-intercepts. This means that they are parallel lines that have a constant distance between them.
First you foil so you would get
0.5r+1.375=3
Then you subtract the 1.375 to the 3
0.5r=3-1.375
0.5r=2.375
Now to find r you need to divide by 0.5
r=2.375/0.5
Answer:
1193.2 sq. in.
Step-by-step explanation:
SA = LA + 2B
where LA is the lateral area and B is the area of the base (circle)
B = πr^2 = 3.14(10)^2 = 3.14(100) = 314
Area of 2 Bases = 2 (314) = 628
LA = Ch where C is the circumference of the base
LA = πdh = 3.14(20)(9) = 565.2
SA = 628 + 565.2 = 1193.2 sq. in.
Answer:
$118.25
Step-by-step explanation:
Always convert the percentage to a decimal by moving the decimal two points to the right/dividing by 100. So 7.5 % = 0.075
110 x 0.075 = 8.25 (the amount of tax added)
110 + 8.25 = 118.25
You can also multiply 110 by 1.075, where the "1" is the $110 and the ".075" is the tax, and save the step of adding. 110 x 1.075 = 118.25
Answer:
No this is not arithmetic this is geometric
Step-by-step explanation:
10 to 15 is a increase of 5
15 to 21 is a increase of 6
21 to 28 is a increase of 7 arithmetic have to have steady increases
