Answer:

B

Step-by-step explanation:

Perpendicular lines have opposite-reciprocal slopes

So if I had a slope of 2, the perpendicular slope would be -1/2.

Or if I had a slope of -7, the reciprocal is -1/7 and the opposite would be 1/7.

Hope this helps!

Answer:

B

Step-by-step explanation:

Remember, perpendicular lines have NEGATIVE RECIPROCAL slopes! This means that a line with a slope of a/b's perpendicular line would be -b/a! You can see that in option B, the slopes of the lines are -7 and 1/7, which are negative reciprocals.

Let's take -7 and flip it, then change the sign:

-7 -> -7/1 -> -1/7 -> 1/7

We just confirmed that -7 and 1/7 are negative reciprocals! Therefore, two lines with these slopes are perpendicular.

The volume is decided by using the equation V (volume)=a^3. This means you multiply the length x hight x width. So we would do 5 x 4 x 2 which equals 40.

To find the slope you rise before you run and if you can't rise then you go downwards so it would be down -3 over positive 2

Please someone HELP QUICK<br> ILL GIVE BRAINLIEST TO CORRECT ANSWER<br><br> HURRYYYYYY
Veseljchak [2.6K]
Okay. So t is in the parenthesis of the equations and represents the number of years after 1950. In this case, the first, second, third, and the seventh tile won't work, because those numbers are too big to be applicable as years. The number of vinyls sold each year would be put behind the equal sign. If you solve it correctly, here are your answers starting from the top:

1. f(8) = 68,594
2. f(11) = 91,299
3. f(2) = 38,720
4. f(17) = 161,743
