Point $Y$ is on a circle and point $P$ lies outside the circle such that $\overline{PY}$ is tangent to the circle. Point $A$ is on the circle such that segment $\overline{PA}$ meets the circle again at point $B$. If $PA = 15$ and $PY = 9$, then what is $AB$? [asy] unitsize(2 cm); pair A, B, P, Y; Y = dir(130); A = dir(20); B = dir(180); P = extension(Y, Y + rotate(90)*(Y), A, B); draw(Circle((0,0),1)); draw(Y--P--A); label("$A$", A, E); label("$B$", B, SW); label("$P$", P, W); label("$Y$", Y, N); [/asy]
Answer:
48/5
Step-by-step explanation:
By power of a point on P, we have PB * PA = PY^2. Therefore,
PB = PY^2/PA = 9^2/15 = 27/5. Then AB = PA - PB = 15 - 27/5 = 48/5

Which of the following points solves the system shown below?
y = 5x -9
y = -2x + 12
Choose from the following...
1) (1, -4) 2) (2,8) 3) (3,6) 4) (-3, 18)
Answer:
(3,6)
Step-by-step explanation:
Collect like terms
y -5x = -9
y + 2x = 12
Using elimination method
Subtract equation 2 from equation 1
y - 5x = -9
y + 2x = 12
---------------
0. -7x = -21
Divide both sides by -7
-7x = -21
---- -----
-7 -7
x = 3
Substitute x=3 into equation 1
y = 5(3) - 9
y = 15 - 9
y = 6
Solution is (x,y) = (3,6)

Jennifer has one more nickel than she has dimes. If she has $1.25 how many of each type of coin does she have? (HELP IS APPRECIATED)
Answer:
She has 9 nickels, and 8 dimes.
Step-by-step explanation:
We know that she has a total of $1.25. We know that a nickel is $0.05, and that a dime is $0.10.
9x$0.05=$0.45
8x$0.10=$0.80
Answer:
9 nickels
8 dimes
Step-by-step explanation:
.05(n + 1) + .10n = 1.25
.05n + .05 + .10n = 1.25
.15n = 1.20
n = 1.2 / .15
n = 8
but there are 9 nickels because there is "one more nickel than dimes"

3) What is the average rate of change between x=2 and x=4?
Answer:
Rate of change = 150%
Rate of change = 100%
Rate of change = 100%
Step-by-step explanation:
Find:
Rate of change
x=2 and x=5
x=3 and x=6
x=2 and x=4
Rate of change = [(5-2)/2]100
Rate of change = 150%
Rate of change = [(6-3)/3]100
Rate of change = 100%
Rate of change = [(4-2)/2]100

Given:
The equation is
[tex]\dfrac{2a-4}{3}=8[/tex]
To find:
The reason for second step.
Solution:
We have,
[tex]\dfrac{2a-4}{3}=8[/tex]
Using multiplication property of equality, multiply both sides by 3.
[tex]3\left(\dfrac{2a-4}{3}\right)=3(8)[/tex]
[tex]2a-4=24[/tex]
Using addition property of equality, add 4 on both sides.
[tex]2a-4+4=24+4[/tex]
[tex]2a=28[/tex]
Using division property of equality, divide both sides by 2.
[tex]\dfrac{2a}{2}=\dfrac{28}{2}[/tex]
[tex]a=14[/tex]
So, the reason for second step is multiplication property (=).
Therefore, the correct option is D.

⇒ 1 hours = 60 minutes
Hence, We can change as;
⇒ 4 1/2 hours = 4 1/2 × 60 minutes
= 9/2 × 60
= 270 minutes
Hence, There are 270 minutes long is the final lesson.

Answer:
20 + -9 + 8 + -7
Step-by-step explanation:
A epression DOES NOT have a equal sign, =
20-9+8-7 = 12
20 + -9 + 8 + -7
to check -->
20 +-9 + 8 + -7
20 + -9 = 20 - 9 = 11
11 + 8 = 19
19 + -7 = 19 - 7 = 12
So therefor it would be
20 + -9 + 8 + -7
