Can someone please explain how they got this answer because the entire lesson they haven’t shown me how to graph these
I am Lyosha [343]

Answer:

Please check explanations

Step-by-step explanation:

Here, we have three types of equations and three plotted graphs

we have a quadratic equation

an exponential equation

and a linear equation

For a quadratic equation, we usually have a parabola

The first equation is quadratic and as such the first graph that is parabolic belongs to it

For an exponential equation, we usually have a graph that rises or falls before becoming flattened

The second equation represents an exponential equation so the second graph is for it

Lastly, we have a linear equation

A linear equation usually has a straight line graph

Thus, as we can see, the third graph represents the linear equation

Help with my homework pls<br> Solve the compound inequality y + 7 ≥ –1 and y∕4 + 3 ≤ 5.
Marianna [84]

Answer:

  -8 ≤ y ≤ 8

Step-by-step explanation:

Subtract 7 from the first one:

  y ≥ -8

Subtract 3 from the second one, then multiply by 4.

  y/4 ≤ 2

  y ≤ 8

Now, you can write these as a compound inequality:

  -8 ≤ y ≤ 8

_____

<em>Additional comment</em>

You basically solve these the same way you would an equation. The only difference is that multiplying or dividing by a negative number will reverse the inequality symbol:

  2 > 1

  -2 < -1 . . . . . multiplied above by -1.
