Step-by-step explanation:

Givenf(x) = [tex]\sqrt{7x-21}[/tex]To find Inverse of f(x)Solution

Change f(x) → x, and x → y, and solve for y:

x = [tex]\sqrt{7y -21}[/tex]x² = 7y - 217y = x² + 21y = 1/7x² + 3

y = f⁻¹(x)

What is a linear equation?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Brian is n years old.

Then the age of Brian after 47 years will be given as,

⇒ n + 47

The age of Brian after 47 years will be n + 47.

Your friend estimated that it would take 5 hours to finish an art project. It actually took him 16 hours to finish the project. The amount of time it took to finish the project was % of the estimated time Use pencil and paper. What does it mean to have more than 100% of something? Give at least two examples The amount of time it took to finish the project was % of the estimated time (Type an integer or a decimal.)​

Answers

Answer:

320%

To have over 100% of something means that you have more than the original number you had.

Step-by-step explanation:

Step-by-step explanation:

To find what percent a first number is of second number, divide the first number by the second number and multiply by 100%.

To find what percent 16 is of 5, divide 16 by 5 and multiply by 100%.

16/5 * 100% = 3.2 * 100% = 320%

"Percent" literally means "per 100."

100% means 100 out of 100, and means an entire amount.

More than 100% percent means more than the entire amount.

5 hours was the estimated time. 100% of 5 hours is 5 hours, the entire amount. More than 100% is more than the entire amount, so it is more than 5 hours. 16 hours is certainly much more than 5 hours, and it is 320% of 5 hours.

The slope is positive.
Oc.
The slope is zero.
D.
The slope is undefined.

Answers

The answer is D that is what I got

The true statement about the slope is the slope is positive.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

To find the slope take two points from the graph as (0, 4) and (5, 6)

So, Slope of line

= (6-4) / (5-0)

= 2 /5

= 0.4

Thus, the slope of line is positive.

What is the value of y in the solution of the system?
x + y = 3
y = -6x + 3

Answers

Step-by-step explanation:

x + y = 3 ------------ eqn 1

y = -6x + 3 ---------- eqn 2

Substitute -6x + 3 for y in equation 1

x - 6x + 3 = 3

Evaluating we have,

-5x = 3 - 3

Evaluating further,

x = 0

Substitute 0 for x in equation 1

0 + y =3

Make y subject of formula

y = 3 - 0

y = 3

1. Determine f -1 (x) for each of the given functions
f (x) =2x-3

2. Determine f -1 (x) for each of the given functions
f (x) = x over x+2​​

Answers

Step-by-step explanation:

1) f(x) =2x -3

y=2x - 3

x= 2y -3

2y =x + 3

y = x+3 over 2

f(x)^-1 = x+3 over 2

2) f(x) = x /x+2

y= x / x+2

y / y+2 = x

y = (y+2)x

y= xy +2x

y -xy = 2x

y( -x +1) = 2x

y= 2x over -x + 1

f(x)^1 = 2x over -x + 1
