when the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs intersect at two places. Write the y-coordinates of the points of intersection in the boxes below in order from smallest to largest

y=2x

y+x^2 - 3

Answers

Answer:

Intersection points (1,2) and (-3,-6)

The y-coordinates of the points of intersection from smallest to largest is -6 to 2.

Step-by-step explanation:

Given : A system of equations y=2x and   y+x^2 - 3=0

To find : Write the y-coordinates of the points of intersection?

Solution :  

Let,y_1=2x

and  y_2=3-x^2

Now, we plot these two equations.

The graph of y_1=2x  is shown with red line.

The graph of y_2=3-x^2  is shown with blue line.

The solution to this system will be their intersection point.

The intersection points of these graph are (1,2) and (-3,-6).

Refer the attached graph below.

Therefore, The y-coordinates of the points of intersection from smallest to largest is -6 to 2.

The answer is -2 and 6

Alicia estimated that the number of horses living in a stable was 26. The actual number of horses living in the stable was 30.What is the percent error in Alicia’s estimate? If necessary, round to the nearest percent.

How would you order the numbers 5.82, 5.7, 5.35, and
5 1/5 from least to greatest?

Answers

Answer:

5 1/5, 5.35, 5.7, 5.82

Step-by-step explanation:

5 1/5 = 5.20

5.35 = 5.35

5.7 = 5.70

5.82 = 5.82

Answer:

A or 5 1/5, 5.35, 5.7, 5.82

Step-by-step explanation:

Determine if the ordered pair (6, 4) is a solution to the inequality y is greater than negative one half times x plus 7. Yes, because (6, 4) is above the line No, because (6, 4) is below the line Yes, because (6, 4) is on the line No, because (6, 4) is on the line

Answers

Answer:

No,because (6,4) is on the line.

Step-by-step explanation:

We are given that an inequality equation

y>-(1)/(2)x+7

We have to find that the ordered pair (6,4) is a solution of given inequality or not.

y>-(x)/(2)+7

Substitute x=6

y>-(6)/(2)+7

y>-3+7

y>4

The value of y is greater than 4 not equal to 4.

Therefore, (6,4) is not a solution of given inequality.

No,because (6,4) is on the line.

Answer:

(6,4) is not a solution of y > -x/2 + 7 because (6,4) is on the line

The answer is D.

Hope this helps!
