Write in slope intercept form an equation of the line that passes through(-4,1), (4,3)
saul85 [17]

Answer:

Step-by-step explanation:

I know this is not your question but it may help

Question:Write an equation in Slope intercept form of the line that passes through the given  points (-3,4) (1,4)

2 Answers:

1: y=x+4

2:

answer would be “y=4”

to find the answer: first you have to find the slope with the given points. (y2 - y1 / x2 - x1)

plug it in to get: (4-4 / 1- -3) = 0/4 = 0

this means the slope would be 0

if the y intercepts are the same then it usually indicates that the slope would be 0 and that the answer is the y intercept.. but if you don’t understand how to get slope-intercept using other coordinates then here’s how:

you can use point-slope formula (y-y1 = m (x-x1) in order to do this just plug in one of the coordinates. in this case an example of point-slope form would be:

y-4 = 0 (x - -3) or y-4 = 0(x-1)

it doesn’t matter which coordinates you use..

then solve the point slope for slope-intercept.

y-4 = 0(x-3) multiply 0 with x and -3

y-4 = 0x move -4 to the right by adding 4

y = 0x + 4 or y = 4 would be your answer!

x = -2   or   x = 7

Step-by-step explanation:

x² - 5x = 14

x² - 5x - 14 = 0

(x+2)(x-7) = 0

x = -2   or   x = 7

Hasan is painting a spherical model of a human cell for his science class. He uses 100π square inches of paint (in one coat) to
babymother [125]

Answer:

10 in

Step-by-step explanation:

So we want to consider the surface area of this sphere.

The formula for surface area of a sphere is A=4 \pi r^2.

So we have that the surface area is 100 \pi.

So I'm going to replace A in A=4 \pi r^2 with  100 \pi.

100\pi=4\pi r^2

Now our main objective here is to solve for r:

Divide both sides by 4 \pi:

\frac{100\pi}{4 \pi}=\frac{4\pi r^2}{4 \pi}

This gets us r^2 by itself:

25=r^2

What number squared gives you 25? If you don't know, just take the square root of both sides giving you:

\sqrt{25}=r

Now you can just put \sqrt{25} in your calculator.  You should get 5.

5 is the radius

The diameter is twice the radius.

So 2(5) is 10, so the diameter is 10 in.
