Answer:

6x-15

Step-by-step explanation:

First plug in 3x-9 for x

2(3x-9) +3

Multiply 2 by (3x-9)

2(3x-9)=6x-18

add 3

6x-18+3=6x-15

hope this helps :)

Answer:

\boxed{\sf f(g(x)) = 6x -15 }

Given:

\sf f(x) =2x + 3 \\ \sf g(x) =  3x - 9

To find:

\sf f(g(x))

Step-by-step explanation:

\sf Evaluate \ f(g (x)) \ by \ substituting \ in \ the \\ \sf value \ of \ g(x) \ into \ f(x): \\ \sf f(3x - 9) = 2(3x - 9) + 3 \\ \\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \sf = (2 \times 3x) - (2 \times 9) + 3 \\ \\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  \sf = 6x - 18 + 3 \\ \\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  \sf = 6x - 15

Answer:

d

Step-by-step explanation:

5x -2

Answer choices:

a. 2-5x

b. 3-5 +2x

c. 5x-2x

d. 2x-2+3x

a.

2-5x can be rewritten as -5x+2, which is not the same as 5x-2

b. 3-5 + 2x can be rewritten as -2 + 2x or 2x-2 which is not equivalent to 5x-2

c. 5x-2x is 3x

3x doesn't equal 5x-2

d. 2x+3x-2 = 5x-2

This expression is equivalent to 5x-2

Question 1
8090 [49]

The correct answer is C. The 13 moose are the individuals. There is one categorical variable and four quantitative variables.

Explanation:

In research, the individuals refer to the participants or population that is being analyzed. For example, if the purpose of the research is to know how many hours highschool students sleep, the individuals are high school students. In this context, the individual or population of this study ae the 13 moose.

Moreover, this research focuses on different variables such as gender, height, the number of hours each moose spends in the water, the weigh of the food eaten on average by each moose, and the average weight of food eaten every day. From these variables, the last four variables are quantitative because they can be measured using numbers, for example, the height is measured in inches. On the other hand, the first variable is categorical because each moose can be classified in only two categories: male or female.
