What is the slope of the line that passes through the points)(7,−4) and (7, 0) ? Write your answer in simplest form.
Slope=Δy/Δx=(y2-y1)/(x2-x1)
The points are (7,-4) and (7,0)
So slope= [ 0 -( -4 ) ] / [ 7 -7 ] = 4/0 =undefined
We know this is the vertical line of x=7 and vertical lines have undefined (or infinite) slope

John made a lump sum deposit of $ 6,300 in an account that pays 6.5% per year. Find
the value (maturity value) of his account after 5 years. How much is the interest?
Answer: $8,347.50 is the value of his account after five years.
Interest is $409.50 per year.
Total amount of interest paid is $2,047.50.
The maturity value in John's account is $8347.5.
Given that, principal =$6300, rate of interest =6.5% and the time period =5 years.
What is the maturity value?Maturity value is the amount due and payable to the holder of a financial obligation as of the maturity date of the obligation. The term usually refers to the remaining principal balance on a loan or bond. In the case of a security, maturity value is the same as par value.
Now, S.I. = (P×T×R)/100
= (6300×5×6.5)/100
= 2047.5
So, interest =$2047.5
Maturity value = Principal + Interest
= 6300+2047.5
= $8347.5
Therefore, the maturity value in John's account is $8347.5.

I’m stuck on a math problem. It’s asking..
You plan to purchase a house for $425,000 and you will make a 30% down payment. You are evaluating two mortgages a 30-year fixed mortgage at 2.77% and a 15 year fixed mortgage at 2.15%. Your goal is to have a monthly payment that fits within your budget.
A. Which mortgage will give you the lowest monthly payment . What will that payment be. How much less will this be than the other monthly mortgage payment.
B. Assuming you take the full term of the mortgage, which mortgage will result in you paying the most interest. What will that interest be? How much less will this be than the interest on on the other mortgage?
Answer:
A. 30 years at 2.77%; $1217.67; $717.38 lower
B. 30 years at 2.77%; $140861.72; $90,051.68 difference
Step-by-step explanation:
A suitable spreadsheet, calculator, or financial app can help you answer these questions. In the attachments, we show the result of using a TI-84 work-alike calculator's financial app.d
A.The lowest monthly payment generally results from the longest-term mortgage, even when the interest rate is slightly higher. Here, the lowest payment is $1217.67 on the 30-year loan. It is $717.38 lower than the payment on the 15-year loan.
__
B.The longer-term loan will generally require payment of more interest. Here, that is made worse by the higher rate on the longer loan. The interest is the sum of payments less the initial principal. The highest amount of interest is $140,861.72 on the 30-year loan. That is $90,051.68 more than for the 15-year loan. (The wording of the question seems to be confused.) The least interest amount is $50,810.04 on the 15-year loan.

Your distance from lightning varies directly with the time it takes you to
hear thunder. If you hear thunder 10 seconds after you see the lightning,
you are about 2 miles from the lightning. Estimate how many seconds it
would take for the thunder to travel a distance of 4 miles? *
Answer:
d = 1/5t
Step-by-step explanation:
Since it is a direct variation , Let d represent the distance and t represent the time ,then
d ∝ t
introducing the proportionality constant, we have
d = kt
Substituting t = 10 and d = 2 , we have
2 = 10k
k = 1/5
substitute k = 1/5 into the original equation , we have
d = 1/5t

A. W
B. X
C. Y
D. Z
By analyzing the data and the interquartile ranges on the graphs, we will conclude that the correct option is A.
Which graph represents the data?The data is:
{10, 8, 50, 15, 10, 25, 20, 5, 12, 15, 20, 15, 25, 18, 20}
You can see that the minimum is 5, and the maximum is 50.
Now, if we analyze our data by ordering it from lowest to largest, we get:
{5, 8, 10, 10, 12, 15, 15, 15, 18, 20, 20, 20, 20, 25, 25, 50}
There are 16 numbers, so each interquartile has 4 elements. If you see the last interquartile (last 4 digits) you can see that it starts with a 20.
The graph where the last interquartile starts at 20, is the first graph, so the correct option is A.

Circle X with a radius of 6 units and circle Y with a radius of 2 units are shown. Circles X and Y are shown. Circle X has a radius of 6 units and circle Y has a radius of 2 units. Which steps would prove the circles similar? Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 4. Translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle Y by a scale factor of 4. Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3. Translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle Y by a scale factor of 3.
The scale is 6/2 = 3
tanslate the circles to have the same center point and scale circle y by a factor of 3.
The answer is C.
Answer:
Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.
Step-by-step explanation:
To prove circles are similar:
Translate the circles so that they share a common center point. (The circles are now concentric as they have the same center).Dilate the smaller circle to increase its size to coincide with the larger circle. The amount that the circle needs to be dilated by is the scale factor.As the radius of circle Y is 2 and the radius of circle X is 6, determine the scale factor by dividing the larger radius by the smaller radius:
scale factor = 6 ÷ 2 = 3
Solution
Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.
Adding and subtracting fractions with different denominators D:
Answer:
(I only did question 11 because the rest is just repetition)
Step-by-step explanation:
make the denominators the same by finding the LCM (lowest common multiple)
(I apologise if I do this incorrectly, the image is very blurry)
So what I did was make the denominator a number that both 2 and 3 can multiply to. (2x3=6 and 3x2=6)
Then whatever you do to the bottom you always do to the top.
- to go from 2 to 6, multiply by 3
- do that to the numerator
- to get from 3 to 6, multiply by 2
- do that to the numerator
= 17/6

A rectangle has an area of 24x + 6. What are all the possible side lengths of the rectangle.
The required possible side lengths of the rectangle are B. 2 and 12x+3 and C. 3 and 8x + 2.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
The area of a rectangle is given by the formula A = l x w, where l is the length and w is the width of the rectangle.
We know that the area of the rectangle is 24x + 6, so we can set up the equation:
24x + 6 = l x w
We want to find all possible combinations of length and width that satisfy this equation.
One way to approach this is to factor the expression 24x + 6 and look for pairs of factors that multiply to give the same product.
24x + 6 = 6(4x + 1)
Now we can see that one possible set of dimensions is:
l = 6(4x + 1)
w = 1
This gives us an area of:
A = l x w = 6(4x + 1) x 1 = 24x + 6
Another possible set of dimensions is:
l = 2(12x + 3)
w = 3
This gives us an area of:
A = l x w = 2(12x + 3) x 3 = 24x + 6
So the possible side lengths of the rectangle are:
l = 6(4x + 1), w = 1
l = 2(12x + 3), w = 3
