(2,4) (x,8) slope = -2

Mathematics
1 answer:
Ket [755]3 years ago
5 0

Answer:

x=0

Step-by-step explanation:

m=\frac{y2-y1}{x2-x1}

1) Plug the points into slope formula, and write -2 as m:

-2=\frac{8-4}{x-2}

2) Multiply both sides by (x-2):

-2(x-2)=8-4

3) Distribute -2 to x and -2:

-2x+4=8-4

4) Simplify:

-2x+4=4

5) Subtract 4 from both sides:

-2x=0

5) Divide both sides by -2:

x=0

The coordinates of the midpoint of GH are M(-2, 0), and the coordinates of one endpoint are H(4,-4).
Svetlanka [38]

The coordinate of point S from the giving coordinate point is (-8,4)

<h3>Midpoint of coordinates</h3>

The formula for calculating the midpoint of coordinate point is expressed as:

M(x,y) = {(x₁+x₂)/2, (y₁+y₂)/2}

Determine the measure of the coordinate S
-2 = 4+x₂/2

2(-2) = 4+x₂

x₂ = -4-4

x₂ = -8

Similarly

0 = -4+y₂/2

0(2) = -4+y₂

y₂ = 4

Hence the coordinate of point S from the giving coordinate point is (-8,4)

A circuit board manufacturer can produce 2,000 boards per hour. How many days will it take to produce 16,500 if the company has
mrs_skeptik [129]
Hi <span>Mrsdiaz1jd1977owwfvt!
OK so 2,000 boards per hour in 10 hours is 2,000*10=20,000 boards in 10 hours. So it can produce 16,500 boards in less than a day.
I may be wrong but I hope this helps!</span>

What is the length? In algebra DUE TOMORROW
Mamont248 [21]
The formula for volume is V=lhw, or length times height times weight. To find the length, you divide the volume by the height and width. 

In this case, divide 3,060 first by 12, the height, then by 15, the width.

3,060/12=255
255/15=17

The length is 17.
