The two variables that exhibit a positive direct linear variation are x and y and the equation is y = 6x

<h3>How to give two variables that exhibit a positive direct linear variation.</h3>

A positive direct linear variation is represented as

y = mx

Where

m represents the constant of variation

In this case,

m can be any value greater than 0

Say m = 6

So, we have

y = 6x

Hence, the two variables that exhibit a positive direct linear variation are x and y and the equation is y = 6x

Solve the system using substitution: y + 8x = 10 and 2y - 4x = 40
exis [7]

Answer:

Hence x = -1 and y = 18

<em></em>

Step-by-step explanation:

Given the system of equations

y + 8x = 10... 1

2y - 4x = 40 ... 2

From 1; y = 10-8x

Substitute into 2;

2(10-8x) - 4x = 40

20 - 16x - 4x = 40

20 - 20x = 40

-20x = 40 - 20

-20x = 20

x = -1

Recall that y = 10-8x

y = 10 - 8(-1)

y = 10 + 8

y = 18

Hence x = -1 and y = 18

Where would we find the point (–10,0)? A. Quadrant III B. y-axis C. Quadrant II D. x-axis
Elina [12.6K]
The answer is D. x-axis, because of the layout of (x,y), meaning there would be an x value of -10, but no y value so it would sit on the x-axis

This is hard for me I need help or my mom is going to be
Harrizon [31]
the answer should be letter A

the difference of 3.4 and 1.25 = 2.15

Now you know that there will be 2 whole blocks and .15 of a block

.15 is equal to 3/20 which is equal to 15/100.

So you will have 2 whole blocks and 15/100 of a blocks. So the answer is A

The Chang family is on their way home from a cross-country road trip. During the trip, the function D (t) = 3260 - 55t can be us
Lilit [14]

Answer:

See below.

Step-by-step explanation:

D(t) = 3260 - 55t

The function that shows their distance from home as a function of time shows that they started 3260 miles from home and are driving at 55 miles per hour.

part a:

D(12) = 3260  55(12)

D(12) = 3260 - 660

D(12) = 2600

Interpretation: After 12 hours of driving home, they are 2600 miles from home.

part b:

D(t) = 2490

3260 - 55t = 2490

-55t = -770

t = 14

Interpretation: When they are 2490 miles from home, they have driven for 14 hours.

On her way to visit her parents,jennifer drives 265 miles in 5 hours. What is her average rate of speed in miles per hour?
Nutka1998 [239]
Her total distance (so 265 miles) over the number of hours she drives will give miles per hour. 
265miles/5hours=53 miles/hour
