Answer:

d. y\geq -1

Step-by-step explanation:

We have been given a graph of an inequality. We are asked to find the inequality that matches our given graph.

Upon looking at our given graph, we can see that boundary line of our given inequality is solid and it is a horizontal line that crosses y-axis at point (0,-1).

We know that equation of a horizontal line is in form y=a, which crosses y-axis at point (0,a).

The equation of boundary line would be y=-1.

The points on the side of boundary line would be y\geq -1 and on the other side would be y\leq -1.

Now, we will check point (0,0) to find the inequality that represents shaded region.

0\leq -1

0\geq -1

Since point (0,0) is shaded in our given graph, therefore, the inequality y\geq -1 matches our given graph and option 'd' is the correct choice.

Would someone mind explaining this?
Nesterboy [21]

Answer:

3?

Step-by-step explanation:

i think that because it's multiplying by 3.

3*3= 9

5*3= 15

7*3= 21

9*3= 27

This is the only way i could think of helping in some sort of way! I'm sorry if it's wrong! (´。_。`)

Have a great day! (´。_。`)  /  (ノ◕ヮ◕)ノ*:・゚✧

Hunter's time for the 100-meter freestyle event was 57.9 seconds. His time for the second half of the race was 4.7 seconds slowe
Ratling [72]

Answer:

Step-by-step explanation:

Time for first race 57.9seconds

x=time for first half of race

x-4.7=second half of race

Equations is

x + (x-4.7)=57.9

2x-4.7=57.9

2x=57.9+4.7

2x=62.6

x=31.3

Check answer

31.3 + (31.3-4.7)=57.9

31.3 +26.6=57.9

57.9=57.9

Problem 1

<h3>Answer:  104 cubic inches</h3>

----------------------

Explanation:

The prisms are similar so they have the same shape, but different sizes.

The linear scale factor from small to large is:

large/small = 10/4 = 2.5

Meaning that we multiply each dimension of the smaller prism by 2.5 to get the corresponding side length of the larger prism

4*2.5 = 10

This linear scale factor is then cubed to get the volume scale factor

(2.5)^3 = 15.625

Which tells us:

larger volume = 15.625*(smaller volume)

smaller volume = (larger volume)/15.625

smaller volume = (1625)/15.625

smaller volume = 104 cubic inches

========================================================

Problem 2

<h3>Answer:  650 square inches</h3>

----------------------

Explanation:

We will go back to the linear scale factor of 2.5

This time, we square it to get (2.5)^2 = 6.25

This is the surface area scale factor.

larger surface area = 6.25*(smaller surface area)

larger surface area = 6.25*(104)

larger surface area = 650 square inches
