Answer:

5

Step-by-step explanation:

its 5

The input in f(5) = 23 is 5.

The function is given as:

f(x) = 4x + 3

In the above function, the input is x and the output is f(x)

This means that the input in f(5) = 23 is 5.

This is so because x = 5

Hence, the input in f(5) = 23 is 5.

Answer:

Skew Is your answer

Step-by-step explanation: Took the test

The correct option is Option D: Line AC and RS are skew lines.

A line is defined as set of points that extends infinitely in either direction. A line is the shortest distance between any two points.

Skew lines are two lines that never intersect and are not parallel also. Hence we can say that the two lines can not exist in the same plane.

From the figure it is clear that

Line AC and RS are in different planes and they are also not intersecting each other, hence according to the definition of skew lines, they are skew lines.

Answer:

(3x+2)^2+1

Step-by-step explanation:

(f°g)(x) =g(f(x)) =g(3x+2)=(3x+2)^2 +1

The required fog ( x ) = 3x² + 5. Option D is correct.

Given that,
If f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (f circle g) (x) is to be determined.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.

Here,
f( x ) = 3x + 2
g( x ) = x² + 1
fog ( x ) = f( g( x ) )
Same as substituting the value of x we substitute a function g inside the function f.
fog ( x ) = 3 (x² + 1) + 2
fog ( x ) = 3x² + 5

Thus, the required fog(x) = 3x² + 5. Option D is correct.

Answer: X = 12

Step-by-step explanation:

So we start off with 10-2x = 5x-50

First off we have to add +2x to isolate 10. After that you have to add 2 to 5x. We should be left off with

10 = -3x-50

Second, you have to use the addition property of equality and add 50 to -50, after that do the same to the other side and add 50 + 10. You should be left off with

60 = 5x

Now use the division property of equality to both sides with 5 because we want to isolate the variable.

60/5 = 12

So X = 12

The slope of the line that passes through the points (2, -5) and (7, 1) is 1.2.

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

Answer:

x=5/4

r =20

Step-by-step explanation:

On the left we have 9x -7

On the right side we have -3x + 8

9x-7 = -3x+8

Add 3x to each side

9x+3x-7 = -3x+3x+8

12x -7 = 8

Add 7 to each side

12x -7+7 = 8+7

12x = 15

Divide each side by 12

12x/12 =15/12

x = 5/4

7+.25r = 12

Subtract 7 from each side

7-7+.25r = 12-7

.25r = 5

Divide each side by .25

.25r/.25 = 5/.25
