Answer:

Please find the attachment for correct choice.

Step-by-step explanation:

We have been given 4 graphs. We are asked to choose the correct linear model for the data.

We know see that our given graphs represents scatter plot. The line of best fit is a linear model or a straight line that best represents the data on a scatter plot.

The line of best passes through some of the points and other points are approximately equidistant form the line.

Upon looking at our given choices, we can see that the line represented in 1st graph is the line of best fit, therefore, 1st option is the correct choice.

1/5z -5/6 = -4/5z -1/3

sveta [45]

Answer:

z = 15/30 = 3/6

Step-by-step explanation:

1/5z - 5/6 = - 4/5z - 1/3

1/5z + 4/5z = - 1/3 + 5/6

5/5z = - 2/6 + 5/6

5/5z = 3/6

z = 3/6 / 5/5

z = 3/6 * 5/5

z = 15/30

-4m + 2n = 6 -4m + n = 8 solve for and x and y steps

hammer [34]

I am doing this problem assuming that you mean to solve for m and n as x and y do not exist in this system of equations.

-4m+2n=6

-4m+n=8

We can see that the coefficient of x for both equations are -4; therefore, elimination with subtraction is possible.

First equation - second equation

n=-2

Then substitude back in to solve for m

-4m+(-2)=8

4m=10

m=5/2

Therefore the answer is

n= - 2

m= 5/2

I hope this helped and if you have any questions please ask.

Find the values of x and y. help please work has to be shown ..

Likurg_2 [28]

Answer:

x = 7 and y = 17

Step-by-step explanation:

16x + 9x + 5 = 180 cuz they are supplementary

25x = 175

x = 7

We also know that 16x + 4y = 180

so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17

hope this makes sense

Answer:

$45+12.5x < 75+7.5x$

Step-by-step explanation:

set each problem to 0 and solve.

Take the answer and plug it in for x. the 1st problem is less than the 2nd.
