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

Answers

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

Answers

Answer:

$1343

Step-by-step explanation:

Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?

You need to turn 15% into a decimal.

Move the decimal point to the left 2 spaces.

15 ---> 1.5 ---> 0.15

Now multiply 0.15 by $1,580.

0.15 × $1,580

Which is $237.

Now subtract $1580 - $237.

Which is $1343.

Answer:

$1580*15/100=$237that is discount rate.

$1580-237=$1343 actually pay

The selling price is: $_________

Answers

Answer:

$145.80

Step-by-step explanation:

The original cost of the product was $90.  There was a 162% markup.  In order to get the selling price, I like to take away 100 percent and simply add original price+(original price*62%).  After taking away 100%, I am left with 62%.  I then multiply the original cost ($90) by the remaining percent (62%), getting 55.8.  Following the steps that I originally wrote, I now add 90 to 55.8, getting 145.8.

A.$380 B. $475
C. $1.520 D. 1.900

Answers

Answer:

b) $475

Step-by-step explanation:

if it has a diameter of 22 feet, that means it has a radius of 11 feet

the formula of the area of a circle is πr². so square the radius and you will get 121, multiply that by π and you get 380

Now we know the area is 380 square feet, so multiply that by $1.25 and the answer is $475

b) $475
Step-by-step explanation:
if it has a diameter of 22 feet, that means it has
a radius of 11 feet
the formula of the area of a circle is Tr?. so
square the radius and you will get 121, multiply
that by TI and you get 380
Now we know the area is 380 square feet, so
multiply that by $1.25 and the answer is $475

What is unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

price of food = $137 . 61

Tip = 18%

tax = 6.5%

Now, price after giving tip

=137.61 x 0.18

= 24.7698

and, after tax

=137.61 x 0.065

=8.94465

Hence, final cost of meal = 137.61 + 24.7698 + 8.94465 = $171.35
