Answer:

The system of equations has no solution

Step-by-step explanation:

The method of substitution consists in solving one equation for a variable and replacing it in the other equation.

In this case one of the equations is already solved for one of the variables ( $y$ ):

$y = -2x + 1$

So the next step is to plug this in the other equation wich is:

$4x + 2y = -3$

So we will have

$4x + 2(-2x + 1) = -3$

solving the parenthesis:

$4x-4x -2= -3$

$-2= -3$

wich is not a valid answer, so the system of equations has no solution.

4x+2(-2x+1)=-3
4x-4x+2=-3
2=-3 is not a true statement.

The answer is no solution

What is 6.685 rounded to the nearest hundredths place

loris [4]

Answer:

6.69

Step-by-step explanation:

The hundredths place is two decimal places to the right. This lands you at 8, so you must look at the number after it to determine whether you round up or down. So you look at 5, which rounds the 8 up to 9. Therefore, it is 6.69

Which function BEST expresses the linear relationship displayed by the scatter plot?

Harrizon [31]

Answer:

Step-by-step explanation:

We want a line of best fit, which means we want to create a line that the data points will lie closest to.

One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.

Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:

(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4

Eliminate A and B.

Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.

The answer is C.

What is the distance between the points?! round to the nearest tenth i need to show work

Contact [7]

Answer:

8.6

Step-by-step explanation:

To find the distance between two points we use the formula posted below

All we need to do is figure out what the points are on the graph and plug them into the formula... we end up with

the square root of (5-(-2)^2+(2-(-3)^2 and get the answer of 8.602325267

then we round to the nearest tenth and get 8.6
