Find the slope perpendicular to the line 21y=-4x

Mathematics
1 answer:
Alexxx [7]2 years ago
4 0

Answer:

21/4

Step-by-step explanation:

21 y = -4x           Divide 21 on both sides

y = -4/21x            Slope is -4/21

Perpendictulare lines have a slope that are the negative inverses of eachother, so flip the 4 and the 21 and make it positve instead of negative

Identify the maximum of the graph below. Type your answer by filling in the blanks below
nevsk [136]

Answer:

The maximum point of this function is (5,4).

Step-by-step explanation:

The maximum of a function is the maximum value that it can take.

Seeing the graph we can say that the maximum value of y occurs at x = 4. Here y = 5 corresponds to this value of x.

Therefore, the maximum point of this function is (5,4).

I hope it helps you!
