What is the equation of the line that passes through the point (8,-4) and has a slope of 3?

2 answers:

8 0

In order to solve it you insert the point in slope from

the equation is
Y=Mx+b

Plug it in as

-4=3(8)+b

-4=24+b

Then subtract 24

B=-28

So

The answer is

Y=3x-28

Y-y1=m(x-x1)

(8, -4) 8 is x1 and -4 is y1
so y- (-4) = 3 (x -8)
make 4 a positive then y + 4 = 3x - 24
subtract 4 from 24 then y=3x-20

You are paying off a student loan in monthly installments. After

dem82 [27]

Answer:

The loan will be paid after 39 monthly installments.

Step-by-step explanation:

Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:

13900 - 13500 = 400

400 x 5 = 2000

2000 + 13500 = 15500

15500/400 = 38.75

Thus, the loan will be paid after 39 monthly installments.

Hi again here's the picture

pshichka [43]

Answer:

Step-by-step explanation:

Given,

D = diameter of semicircular part = 42 m

L = Length of straight part = 110 m

Now, let's find the perimeter:

= 2 ( length of semi-circle + length of straight part )

$= 2( \frac{\pi \: d}{2} + l)$

Plug the values

$= 2( \frac{3.14 \times 42}{2} + 110)$

Calculate the product

$= 2( \frac{131.88}{2} + 110)$

Divide

$= 2 (65.94 + 110)$

Calculate the sum

$= 2 \times 175.94$

Calculate

$= 351.88 \: m$

Hope this helps..

Best regards!!

In the triangle below, the value of a is 12.6.<br><br> True<br><br> False

aev [14]

Answer:

True

Step-by-step explanation:

Formula

Tan(x) = opposite / adjacent

Givens

x = 42

adjacent = 14

opposite = ?

Solution

Tan(42) = opp/14 Find tan(42)

Tan(42) = 0.900404

0.900404 = opp/ 14 Multiply both sides by 14

14 * 0.900404 = opp/14 * 14 Simplify the left

12.6 rounded = opp

a = 12.6
