The perimeter of any shape is the distance all the way around it.

For a triangle, it's the sum of the three side lengths.

I would normally copy them into my answer and then add them up.
But you've set them up in such a beautiful table in the question,
you can just look at that list and add them up.

Add up all the x's : x + x + x = 3x

Add up all the plain numbers: -3 + 2 + 4 = 3

There's your perimeter . . . . . 3x + 3 .

Suzanne read 87 pages of her book in 3 hours. At this rate, how many pages can Suzanne read in 5 hours?

ruslelena [56]

Answer:

145

Step-by-step explanation:

Rate (no. of pages per hour)

= 87 ÷ 3

= 29

5 hours

= no. of pages per hour × 5

= 29 × 5

= 145

hope it helps :))

Consider the point P = (4,-1) and the line L, given by the equation y=2x+3.

3241004551 [841]

Answer:

A. y=2x-9

B. $y=-\frac{1}{2}x+1$

Step-by-step explanation:

A. Parallel lines have the same slope. That means the line y=2x+3 has the same slope as any line parallel to it. So the slope is 2.

Using m=2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.

$y-y_1 = m(x-x_1)\\y--1=2(x-4)\\y+1=2(x-4)\\y+1=2x-8\\y=2x-9$

B. Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=2x+3 is 2. The slope perpendicular to it is -1/2.

Using m=-1/2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.

$y-y_1 = m(x-x_1)\\y--1=-\frac{1}{2}(x-4)\\y+1=-\frac{1}{2}(x-4)\\y+1=-\frac{1}{2}x+2\\y=-\frac{1}{2}x+1$
