A subset of values of the function g(x) is shown in the following table.

Answers

Answer:

Option (4)

Step-by-step explanation:

x              g(x)            Ist difference          IInd difference        Ratio

1              13                      -                                   -                        -

2              3                3 - 13 = -10                         -                       [tex]\frac{3}{13}[/tex]  

3             -3               -3 - 3 = -6                   -6 - (-10) = 4            [tex]\frac{-3}{3}=-1[/tex]

4             -5               -5 - (-3) = -2                -2 - (-6) = 4             [tex]\frac{-5}{-3}=\frac{5}{3}[/tex]

5             -3               -3 - (-5) = 2                   2 - (-2) = 4            [tex]\frac{-3}{-5}=\frac{3}{5}[/tex]

This table depicts,

1). Ist difference is not common

2). IInd difference is common

3). Ratio is not common

Therefore, this table represents a quadratic function because the second difference are all the same value.

Option (4) will be the answer.

Elise says, "If you subtract 18 from my number and multiply the difference by - 3, the result is
- 33." What is Elise's number?

Answers

Elise's number is 29.

If you think of multiplying a value by -3 to get -33, it would obviously be 11.

So in this case, you would want to add 18 to 11 to get Elise's number, which is 29. Subtracting 18 from 29 would get you back to the value of 11, which you can then multiply it by  -3 again to get -33.

What are similar triangles?

Similar triangle are those which have two pairs of interior corresponding angles are equal.

We have,

Two triangles as shown in the given figure,

Now,

Both the given triangles have 90° corresponding angles and also the opposite angle of 90° of both triangles is equal.

So,

Using triangle similarity rule,

i.e.

Sides are in equal proportion,

i.e.

[tex]\frac{49}{x} =\frac{14}{2}[/tex]

⇒

14x = 49 × 2

14x = 98

[tex]x=\frac{98}{14}[/tex]

x = 7

Hence, we can say that the value of x in the given diagram will be 7.
