Answer:

In the equation y=mx+b m is the slope of the line.

Therefore the coefficient in each of these equations is the slope.

A line with a perpendicular slope must have the inverse opposite of the actual line. For example if a line has a slope of 5, a perpendicular line to that line must have a slope of -1/5. If a line has a slope of 10, the perpendicular line has a slope of -1/10. If a line has a slope of 2 then the inverse opposite is -1/2 and that is the slope of the perpendicular line.

B is the only answer with the correct slope so B is the answer.

A rabbit population doubles every 4 weeks. There are currently five rabbits in a restricted area. If t represents the time, in w

My name is Ann [436]

First, you have to find how many weeks are in 98 and to do so, you would divide it by 7. which turns out to be 14. If you divide 14 by 4 you'll find that their population will double 3 times, but not 3.5 because it is every 4 full weeks.
The equation will look like this, however, I'm not completely certain about the format. I'm using the formula for exponential growth
P(t)=r(2)^t
I did use t as weeks, but for every 4 weeks. R is the number of rabbits. If we were to input our information, we'd get:
P(3)=5(2)^3
If you work it out, you get 40 rabbits. In 14 weeks, the rabbits will double 3 times, so if we were to just figure it out without using the formula, we could double 5 which is 10, double it again, which is 20, and then double it a third time. which is 40.

How many triangles exist with the given side lengths? 13, 15, 17

aksik [14]

Answer:

Step-by-step explanation:

13, 15, 27 and 13, 27, 15

you could rearrange the order but they would still be the same two triangles in different rotated positions:

15, 13, 27 is the same as 13, 27, 15, just rotated

15, 27, 13 is the same as 13, 15, 27, just rotated

27, 13, 15 is the same as 13, 15, 27, just rotated

27, 15, 13 is the same as 13, 27, 15, just rotated
