Answer: (1,-2), (1, 3)

Step-by-step explanation:y=2x+1

Y=2(1)+1

Y=2+1

Y=3

3=2x+1

-1 -1

2=2x

2 2

X= 1 new you got your perpendicular line

So answer is (1, -2), (1, 3)

Which symbol correctly compares these two fractions?<br> 4/7 and 8/16

WITCHER [35]

Answer: 4/7 > 8/16

Step-by-step explanation:

Draw each fraction on a fraction bar (similar to a Hersey's Bar each fraction bar being the same length just broken up differently to represent each fraction) and you will see that 4/7 is bigger than 8/16.

A bank loans a family $90,000 at 4.5% annual interest rate to purchase a house. The family agrees to pay the loan off by making

Naily [24]

Using it's formula, it is found that the monthly payment should be of $688.49 in order to pay off the debt in 15 years.

<h3>What is the monthly payment formula?</h3>

It is given by:

$A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}$

In which:

P is the initial amount.

r is the interest rate.

n is the number of payments.

For this problem, the parameters are given as follows:

A = 90000, r = 0.045, n = 15 x 12 = 180.

Hence:

r/12 = 0.045/12 = 0.00375.

Then we solve for A to find the monthly payment, as follows.

$A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}$

$A = 90000(0.00375)\frac{(1.00375)^{180}}{(1.00375)^{180} - 1}$

A = $688.49

Over the last three evenings, Latoya received a total of 79 phone calls at the call center. The first evening, she received 6 fe

Elodia [21]

We need to represent the numbers of calls symbolically:

Third evening: x calls
First eve: x-6 calls
Second evening: 3x calls

Find x. Add up these three numbers x, x-6 and 3x and equate your sum to 79:

x+x-6+3x = 79. Then 5x=79+6, or 5x = 85. Thus, x = 17.

17 calls on the 3rd night,
17-6 calls on the 1st night, and
3(17) = 51 calls on the 2nd night.

Check! Add together 17, 11 and 51. Do these add up to 79? Yes.
