The first thing you should do is observe the behavior of the graph.
 It is not linear because the rate of change is not constant.
 It is not exponential because the rate of change does not grow or decrease rapidly.
 For this case the best regression model is a model of the form:
 y = ax ^ 2 + bx + c

 Where,
 a <0: This is because we have a parabola that opens downwards.
 Therefore, the best regression model is quadratic.

Answer:

  152°

Step-by-step explanation:

If two pairs of congruent angles total 360°, then the different angles must total 180°. The other angle measure is 180° -28° = 152°.

The measure of each angle in the other congruent pair is 152°.

Solve using elimination.<br><br> –9x + 9y = 18<br> –6x + 9y = –12
Arada [10]
You can multiply either the top or bottom equation by -1 so lets say you apply it to the bottom equation it’ll look like this:

-9x + 9y = 18
6x - 9y = 12

then the +9y and -9y will cancel out

-9x = 18
6x =12

then you add the two equations together

-3x = 30

divide both sides by -3

x = -10

What function is graphed below?
tester [92]
The answer for the exercise shown above is the first option, which is:
<span> f(x)=log(x-3) 
 The explanation is shown below:
 If you substitute the x in the function for values, you will obtain the graph attached above. As you can see on the mentioned graph, when the variable x has the value 4, the value y is 0. Therefore, you have:
 </span> f(x)=log(x-3) 
  f(x)=log(4-3) 
  f(x)=log(1)
  f(x)=0<span>
 </span>

Are the following expressions equivalent? Why or why not? <br> 6(2x + 4) and 12x + 24
MrMuchimi

Answer: Yes

Step-by-step explanation:

When using the distributive property, 6(2x + 4) becomes 12x + 24

6 * 2x = 12x and 6 * 4 = 24

12x + 24 = 12x + 24

Therefore, the expressions are equivalent.
