One hour is equal to 60 minutes. That gives you a fraction of 40 pages/60 minutes.

You don't know how many pages they can read in 90 minutes, so you would do
x pages/90 minutes.

The equation you would set up is 40/60 = x/90.

After cross multiplying you get 60x = 3600. Divide both sides by 60 to isloate the x, and you end up with x = 60.

A proofreader who can read 40 pages in one hour (60 minutes) can reading 60 pages in 90 minutes.

40 pages = 60 minutes
20 pages = 30 minutes
60 pages = 90 minutes

Then do multiplication and division:

9+24-2

Then addition and subtraction last:

The given line passes through the points (-4, -3) and (4,
drek231 [11]

Answer:

y = 2x + 11

Step-by-step explanation:

The first thing we need to do

is to find the slope of the line that passes through the points (-4,-3) and (4,1)

Mathematically, that would be;

m = y2-y1/(x2-x1)

where (x1,y1) = (-4,-3) and (x2,y2) = (4,1)

substituting these. values we have;

m = (1-(-3))/(4-(-4)) = 4/8 = 1/2 or 0.5

Now we are told this line is perpendicular to another line that passes through another point.

We can find the slope of this other line

Since both lines are perpendicular, the product of their slope is -1.

Thus , -0.5 * m = -1

m = -1/-0.5 = 2

So the slope of the other line is 2

Using the point-slope form;

y-y1= m(x-x1)

The point for the other line is (-4,3)

So the equation will be

y-3 = 2(x+4)

y-3 = 2x + 8

y = 2x + 11
