Given the function below, find x if f(x)=11
f(x) = 3x + 5

Answers

Answer 1
x = 2
plug in 11 into f(x) and you get 11 = 3x + 5
subtract 5 from both sides and you get 6 = 3x
divide 3 from both sides and you get x = 2
if you plug in 2 for x, you should get 11.

A discount movie pass cost 10.99. With the pass,movie tickets cost 4.25 dollars each. Feen spent a total of 61.99 dollars on the pass and the movie tickets. write an equation to determine how many movie fren watched

Answers

The equation would be (61.99-10.99)/4.25= x
You subtract the price of the pass from the total (61.99-10.99) then you’d divide that by 4.25 to see how many movies she watched
61.99-10.99= 51... 51/4.25= 12 she watched a total of 12 movies

5
OD. The data represent a linear function because there is a common
difference of -9.

Answers

Answer:

The common difference is same = d = -9

Therefore, the data represent a linear function.

Step-by-step explanation:

Given the table

x                        y

1                         4

2                        -5

3                        -14

4                        -23

5                         -32

Finding the common difference between all the adjacent terms of y-values

d = -5 - 4 = -6,

d = -14 - (-5) = -14+5 = -9

d = -23 - (-14) = -23 + 14 = -9

d = -32 - (-23) = -32 + 23 = -9

It is clear that the common difference between all the adjacent terms is same.

Thus,

d = -9

We know that when y varies directly with x, the function is a linear function.

Here, it is clear that each x value varies 1 unit, and each y value varies -9 units.

i.e. The common difference is same = d = -9

Therefore, the data represent a linear function.
