Answers
Answer:
(0, -2)
Step-by-step explanation:
The y-intercept is where the graph crosses through the y axis, when x is equal to 0. On this graph, the line goes through the y-axis at -2. At -2, we can also see that x=0
In general, the y-axis of a graph will always be (0, y).

Oceanside Bike Rental Shop charges 12 dollars plus 6 dollars an hour for renting a bike. Write an expression for the cost of renting bikes for x hours.
Answers
Answer:
[tex]y = 12 + 6x[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = 12[/tex]
[tex]Additional = 6[/tex] per hour
Required
Determine the expression for the cost in x hours
Represent the cost with y
y is calculated using the following expression
[tex]y = Base\ Amount + Additional * x[/tex]
Where x represent the number of hours.
Substitute values for the base amount of bike and the additional cost per hour
[tex]y = 12 + 6 * x[/tex]
[tex]y = 12 + 6x[/tex]
So, the expression to determine the cost of bike in x hours is: [tex]y = 12 + 6x[/tex]
Carlos pays $25 for skis and borrows the remaining amount. The loan payments are $75 every 3 months for 1/1/2 years. The interest rate is 16.2%/a compounded quarterly. What was the selling price of the skis?
Answers
Answer:
$417.52
Step-by-step explanation:
Present value of annuity = P * {1-[1/(1+r)^n]/r}
P =Periodic payment i.e. 75
r = rate of interest per period i.e. 16.2% /4 = 4.05% or 0.0405
n =no. of compounding period i.e. 1.50*4 =6
Present value of annuity = Loan amount
Present value of annuity = 75 * {1-[1/(1+0.0405)^6]/0.0405}
Present value of annuity = 75 * {1-[1/(1.0405)^6]/0.0405}
Present value of annuity = 75 * {1-[1/1.268973)/0.0405}
Present value of annuity = 75 * (1-0.78804)/0.0405
Present value of annuity = 75 * (0.21196/0.0405)
Present value of annuity = 75 * 5.23361
Present value of annuity = 392.52
Loan amount = $392.52
Selling price = $392.52 + $25.00
Selling price = $417.52
Thus, the selling price of the skis is $417.52
i need help what is w-8=32
Answers
Answer:
w=40
Step-by-step explanation:
w=40 because when you subtract 40-8 the sum is 32 so W=40
w-8=32
------------------------------------------------------------------------------------------------------
add 8 to -8, and 32.
8 and -8 will cancel out. 32 and 8 will increase though. So, it should be:

An architect designs two similar triangular patios. The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°. The second patio has angle measures of (x + 20)°, 50°, and 60°. Find the values of x and y.
Answers
Given:
An architect designs two similar triangular patios.
The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°.
The second patio has angle measures of (x + 20)°, 50°, and 60°.
To find:
The values of x and y.
Solution:
We know that, corresponding angles of similar triangles are equal. So, the value of (x + 20)° must be 70°.
[tex]x+20=70[/tex]
[tex]x=70-20[/tex]
[tex]x=50[/tex]
The value of x is 50.
Now,
[tex](x+10)^\circ=(50+10)^\circ[/tex]
[tex](x+10)^\circ=(60)^\circ[/tex]
So, remaining angles must be equal, i.e., (y + 15)° and 50° are equal.
[tex]y+15=50[/tex]
[tex]y=50-15[/tex]
[tex]y=35[/tex]
Therefore, the values of x and y are 50 and 35 respectively.
The values of x and y are 50 and 35 respectively.
The corresponding angles of similar triangles are equal. Therefore,
The first patio angles are:
x + 10
y + 15
70°
The second patio angles are ;
x + 20
50°
60°
Therefore,
x + 20 = 70
x = 70 - 20
x = 50
y + 15 = 50
y = 50 - 15
y = 35

Dr. Cohn is testing how long it takes for a person's body to process a new medicine. She observes that the medicine is used by the body at a constant rate. For her latest test, Dr. Cohn starts with 15 milligrams of the medicine and notes that 12.6 milligrams remain unused after 1 hour. Which equation could Dr. Cohn use to solve for p, the percentage of the medicine that is used in 1 hour? A. p100=12.615 B. p100=2.415 C. p15=1002.4 D. p15=10012.6
Answers
Answer:
the options were not copied correctly, option B could be correct but it is missing the division signs:
B. p / 100 = 2.4 / 15
the percentage of medicine used in 1 hour:
p / 100 = (15 - 12.6) / 15 = 2.4 / 15
p / 100 = 0.16
p = 0.16 x 100 = 16%
another option could be C but it would be missing the multiplication signs:
C. p x 15 = 100 x 2.4
p x 15 = 240
p = 240 / 15 = 16%
