Answer:

y = 4x - 3

Step-by-step explanation:

When we re-write the given equation into its slope-intercept form, it will like this:

y = (-1/4)x - 6

This line has a slope equal to -1/4 so the slope of the required line has a slope of +4 (perpendicular to the given line). Use this new slope and the given point P0(-1, -7) into this equation:

y - y0 = m(x - x0) ---> y + 7 = 4(x + 1)

Rearranging the terms into its slope-intercept form, we get

y = 4x - 3

How many miles does it travel in 1 hour?
podryga [215]
It would be 2.1 hours or about 2 hours.

It says the train travels about 2118 miles per 8 miles. So, divide 2118 by 8, which gives you 264.75 (when you see the word PER it usually indicates to divide). That gives you part A.

Then, you divide 560, (which is t<span>he distance between Columbus, Ohio, and New York) by 264.75  to see how many hours it took, which gives you 2.1152030217...., which simplifies to 2.1. Which gives you the answer for B. 

So, 
A is 560 and
B is 2.1  or 2

Find the surface area of the figure
belka [17]

Answer:

122.30 cm²

Step-by-step explanation:

The figure is a triangular prism.

Formula for calculating surface area of a triangular prism = bh + L(S1 + S2 + S3)

Where,

b = 11 cm

h = 4.3 cm

S1 = 8 cm

S2 = 6 cm

S3 = 11 cm

L = 3 cm

Surface area = 11*4.3 + 3(8 + 6 + 11)

= 47.3 + 3(25)

= 122.3 cm²

I think that she could buy 3 tubes of paint because that's $25.50 and that gives you 28.50 for the canvas.

I need help on all of these
lord [1]

well #7 is a solution.

y= 9x (4,36)

9 times 4 = 36

36/9=4

so the ordered pair is a solution.

y=3x-5 (7,16)

3 times 7 -5= 16

so once again the ordered pair is a solution.


Hoped this helped.
