Determine the equation of the line that passes through the points (-1 , 10) and (2,4)
docker41 [41]

Given:

The two points are (-1,10) and (2,4).

To find:

The equation of line which passes though the given points.

Solution:

If a line passes through two points, then the equation of line is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

The line passes through (-1,10) and (2,4). So, the equation of line is

y-10=\dfrac{4-10}{2-(-1)}(x-(-1))

y-10=\dfrac{-6}{2+1}(x+1)

y-10=\dfrac{-6}{3}(x+1)

y-10=-2(x+1)

Using distributive property, we get

y-10=-2x-2

Adding 10 both sides, we get

y=-2x-2+10

y=-2x+8

Therefore, the required equation of line is y=-2x+8.

At your job, you make $8 per hour, and are promised to get a $0.03 per month. Your friend makes $8.15, and is promised a $0.02 r
Rudik [331]

Answer:

3883.2 dollars.

Step-by-step explanation:

We must analyze the situation of each one,

The first tells us to earn 8 dollars an hour, he is promised to receive 0.03 dollars per month, which means that he would already have that increase that month. Therefore, you would have 8.03 per hour of earnings.

The second, on the other hand, although he earns $ 8.15 per hour, the increase is promised every month, that is, it is NO month with the increase of 0.02.

Now assuming they work 8 hours a day and 30 days a month, it would be a total of 8 * 30 = 240 hours.

Now multiplying your hourly income, we will get what each person earns per month.

8.03 * 240 = 1927.2 dollars

8.15 * 240 = 1956 dollars

Which means that both will earn a total of:

1927.2 + 1956 = 3883.2 dollars.

Which factors is multiplied and give you 24 and when added gives you -4
klio [65]

Answer: the no.s are-

2.472

-6.472

Step-by-step explanation:

xy=24-----1

x+y=-4------2

from 2 we get x=-4-y

sustituting=

into 1 we get

quadratic eq = y^2 + 4y + 24=0

so

-4+- root 16-96/2

thus on further solving we get -2 +-4.472

on adding= -2+4.472= 2.472

on subtraction= -2 -4.472= -6.472
