Answer:
The y-intercept of the line is 9.
Step-by-step explanation:
y-y1=m(x-x1)
y-1=-2(x-4)
y-1=-2x+8
y=-2x+8+1
y=-2x+9
y=mx+b where m=slope and b=y-intercept

Please Help!!!!! You have twice as many nickels as pennies. you have $1.10. how many of each coin do you have? Solve each problem using a system of equations.
Answer:
Step-by-step explanation:
n=2p
p+5n=110, using n found above makes this become
p+5(2p)=110
p+10p=110
11p=110
p=10, since n=2p
n=2(10)
n=20
So there are 10 pennies and 20 nickels.

A house cast 65-foot shadow. A person standing nearby cast 7.2 foot shadow. Their height is 4.8 feet. What is the height of the house?
Answer:
42.43 feets
Step-by-step explanation:
Given :
(Height of house / shadow of house) = (height of person / shadow of person)
(height of house / 65) = (4.8 / 7.2)
Cross multiply
Height of house * 7.2 = 4.7 * 65
Height of house = 305.5 / 7.2
Height of house = 42.43 feets

Step-by-step explanation:
If a triangle has A as 4 and B as 13, but C, the hypotenuse, is missing, what is C? I already got to square root of 185 but i don't understand what to do because you can't simplify it, please show your work/explain it
Answer:
C = √185 or 13.6 units.
and cannot be simplified any further because it is irrational.
Step-by-step explanation:
Since the triangle has sides A = 4 units and B = 13 units. With C as its hypotenuse side, from Pythagoras' theorem C² = A² + B².
So, substituting A and B into the equation, we have
C² = 4² + 13²
C² = 16 + 169
C² = 185
taking square root of both sides, we have
√C² = √185
C = √185
C cannot be simplified any further because it is irrational. It is best expressed as √185 which is a surd. C could also be expressed as a decimal. So using your calculator and taking √185, C = √185 = 13.605 ≅ 13.6 units.

The hypotenuse of a 30 -60 -90 triangle is 13cm. What is the length of the shorter leg?
Answer:
(13/2) cm
Step-by-step explanation:
The hypotenuse here is of length 13 cm. The shorter leg lies opposite to the 30° angle. Recall that the sine function is defined as
opposite side
sin Ф = -----------------------
hypotenuse
which, in this case, works out to:
opposite side
sin 30° = -----------------------
13 cm
and so the length of the opposite side (which is also the "shorter leg") is
shorter leg length = (13 cm)(sin 30°) = (13 cm)(1/2) = (13/2) cm

Pennsylvania has a sales tax of 6%. The city of Philadelphia adds an extra local sales tax of 2%. Both taxes apply to the original price of an item. If the shelf price of a bottle of sports drink is $2 in Philadelphia, PA, which expressions can be used to show the total taxes you would expect to pay?
Answer:
For the regular tax in Pennsylvania, it would be 12 cents or $0.12. For Philadelphia, it would be 4 cents or $0.04. I got these two amounts by multiplying 2 times 6 or 2 percent, aka 0.06 and 0.02. If you added the two together, you would get, $0.16 or 16 cents. You would then add that to the two dollars and end up with $2.16 or two dollars and sixteen cents. I hope this helps.
