C= -3 and d=15

I took the 'c' term out of the left side
c multiplied by 4x makes -12x so c must be -3
that means that -3 multiplied by -5 equals d (which is 15)

A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function?
mamaluj [8]

Answer:

Option C. y=(3/4)x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

so

Find the value of the constant k

For the point (-8,-6)

k=y/x=(-6/-8)=3/4

For the point (12,9)

k=y/x=(9/12)=3/4

<u><em>Note</em></u> A single point was required to find the constant k (because the line passes through the origin)

The equation is equal to

y=(3/4)x

What is the variance of the data set? 8, 9, 10, 16, 17
adoni [48]
Mean = (8 + 9 + 10 + 16 + 17) / 5 = 60/5 = 12.

x - mean:

8 - 12 = -4,  -4² = 16

<span>9 - 12 = -3,  -3² = 9
</span>
<span>10 - 12 = -2,  -2² = 4
</span>
<span>16- 12 = 4,  4² = 16</span>

<span>17- 12 = -5,  -5² = 25
</span>
Sum of the squares =   16 + 9 + 4 + 16 +25 = 70

Variance = 70/5 = 14

Variance = 14

Solve for x.<br> y = (5+x}m<br> Answer?
Tanzania [10]

Answer:

x=ym−4

Step-by-step explanation:

y=(4+x)m

Here we have one equation with three unknowns. This cannot be "solved". We can only express one variable in terms of the other two.

Let's isolate x.

Divide through by m

ym=4+x

x=ym−4

(I really hope this helps)
