Write and equation of the line that passes through the point (2,4) and is perpendicular tothe line hows equation is 3y-6x+3

1 answer:

5 0

First, you need to find the slope of this new line.
It is perpendicular to the given line, which means the slope of this line is the negative reciprocal of this given line, so we need to find out the slope of the equation 3y=6x+3
divide each side by 3, you'll get y=2x+1, so we know the slope is 2, which is 2/1
the slope for the new line should be -1/2, the negative reciprocal of 1/2
Next, use point-slope format to write your equation. Your point is (2,4) and your slope is -1/2, so you have
(y-4)=-1/2(x-2)
If you want to simplify it: y-4=-1/2x+1 => y=(-1/2)x+5

Identify the property used in the first five steps to solve the equation 2(x-5)-6x=-22

Alona [7]

To answer this question, you need to multiply the number inside the bracket first. Then you can move the number to the right side of the equal sign and keep the x on the left side of the equal sign. The step would be like this
2(x – 5) - 6x= -22(2x - 10) - 6x = -222x - 6x = -22 +10-4x= -12x= -12/-4x=3
Hope this helps!!!

Determine whether abc ----> jgh is a reflection, translation, rotation, or glide reflection.

Usimov [2.4K]

From this picture you can calculate coordinates of triangles' vertices:
$A(-9,0),\ B(-6,-4),\ C(-3,0),\ J(8,0),\ G(5,4),\ H(2,0)$ .

Since

$\frac{-9+8}{2} = \frac{-6+5}{2}= \frac{-3+2}{2}=- \frac{1}{2}$ $\frac{0+0}{2}= \frac{-4+4}{2} = \frac{0+0}{2} =0$

you can conclude that points A, B, C are rotated by $180^0$ about the point (-0.5,0) to form points J, G, H, respectively.

Answer: A is correct choice.

Working together, it takes two computers 20 minutes to send out a company's email. If it takes the slower computer 45 minutes to

11Alexandr11 [23.1K]

Answer:

36 minutes

Step-by-step explanation:

Let the productivity of slower computer is x bits/min

That means Slower computer in 45 minutes sends x*45 bits= company's email

Let the productivity of faster computer is y bits/min

That means that working together slower and faster computers send

x*20+y*20= company's email or

x*20+y*20=x*45

x*25=y*20

y/x=25/20= 1,25

That means that faster computer sends the mails 1.25 times faster than slower computer

So faster computer will need in 1.25 times lees time than slower computer to do this job

45:1.25 =36 min
