<h3>Answer:  8</h3>

===========================================================

Explanation:

All direct variation equations are of the form y = kx, for some constant k.

We know that y = -8 and x = 4 pair up together. Let's use these two values to find k

y = kx

-8 = k*4

-8/4 = k

-2 = k

k = -2

Therefore, we go from y = kx to y = -2x

We can then find y when x = -4

y = -2x

y = -2*(-4)

y = 8

Answer:

y∝x

y=kx

k=y/x

by putting values

k=-8/4

k= -2

now ,if x= -4

as, y=kx

hence, y= (-2)(-4)

y=8

Use the dots for one and two. what is the difference between the ranges
sergij07 [2.7K]

Answer:

a. 20 points

Step-by-step explanation:

Range = Largest given value - Smallest given value.

<u>Identifying the range of test 1</u>

Looking at the dot plot the lowest test grade appears to be 50 while the highest is 90.

So range of test 1 = 90 - 50 = 40

<u>Identifying the range of test 2</u>

Looking at the plot the lowest test grade appears to be 40 while the highest appears to be 100

So range = 100 - 40 = 60

<u>Identifying the differences between the ranges</u>

Test 1 range : 40

Test 2 range : 60

Difference between the two : 60 - 40 = 20 points

Find the distance from the point to the given plane. (−8, 7, 6), x − 2y − 4z = 8
vlabodo [156]
The formula for the distance from a point (x, y, z) to the plane ax +by +cz +d = 0 is this:
.. distance = |ax +by +cz +d|/√(a^2 +b^2 +c^2)

For your point and plane, that is
.. distance = |-8 -2*7 -4*6 -8|/√(1^2 +2^2 +4^2)
.. = 54/√21
.. = (18/7)√21
