Reflected over the x axis and rotated 180° is your answer

First, note that the horizontal line is the x- axis, and that the figure is reflected over the x- axis.

Next, note that the placement of each point is not exactly identical. Instead, it is flipped. This means that the side is rotated 180°

hope this helps

Determine whether the relationship is a function. Explain your reasoning.

What are the first four terms of the sequence represented by the expression n(n – 1) – 4? A. –2, 2, 6, 10 B. –3, 0, 3, 6 C. –4,
vesna_86 [32]

Answer:

C

Step-by-step explanation:

to find the first 4 terms, substitute n = 1, 2, 3, 4 into the expression

n = 1  → 1(1 - 1) - 4 = 0 - 4 = - 4

n = 2 → 2(2 - 1) - 4 = 2 - 4 = - 2

n = 3 → 3(3 - 1) - 4 = 6 - 4 = 2

n = 4 → 4(4 - 1) - 4 = 12 - 4 = 8

the first four terms are - 4, - 2, 2, 8 → C

Find the equation of a line parallel to y - 5 = 6x - 10 that passes through the point (4, 10). (answer in slope-intercept form)
UNO [17]
Our equation is y = 6x - 5 when simplified. In order to be parallel, the equation for the answer must also have a slope of 6x. This rules out options C and D.

Now just plug in 4 for the x-value for each one to get your answer. A little mental math and I can already tell you it's option A.

6(4) - 14 = y
24 - 14 = y
10 = y

10 = 10

Whereas for option B:

6(4) + 14 = y
24 + 14 = y
38 = y

38 ≠ 10

Option A is your answer.

Michael obtains a 30/8 balloon mortgage to finance $425,500 at 6.55%. How much principal and interest will he have already paid
STALIN [3.7K]

Answer:

$259 532  

Step-by-step explanation:

Step 1. Calculate the monthly payments on a 30-year loan.

The formula for the monthly payment (P) on a loan of A dollars that is paid back in equal monthly payments over n months, at an annual interest rate

of r % is

P = A(\frac{r}{1-(1+r)^{-n}})

<em>Data: </em>

We must express the interest rate on a monthly basis.

i = 6.55 %/yr = 0.545 83 %/mo = 0.005 4583

A = $425 500

n = 360 mo

<em>Calculation: </em>

P = 425 500(\frac{0.005 4853}{1-(1+0.005 4583)^{-360}})

P = \frac{2332.22}{{1- {1.005 4583}}^{-360}}

P = \frac{2332.52}{1 – 0.140907}

P = \frac{2332.52}{0.859 093}

P = $2703.46

B. Total Payment (T) after 8 years

T = nP

T = 96 × 2703.46

T = $259 532

Michael will have paid $259 532 at the end of eight years.
