Divide 12 by 2 (square A's side) = 6

Multiply 6 by 3 (square B's side) = 18

What is the solution to the equation ? (x - 2) ^ (1/2) + 4 = x

Answers

Answer:

x is equal to both 3 and 6.

Step-by-step explanation:

[tex]\sqrt{x - 2} + 4 = x\\\sqrt{x - 2} = x - 4\\x - 2 = (x - 4)^2\\x - 2 = x^2 - 8x + 16\\x^2 - 9x + 18 = 0\\(x - 3)(x - 6) = 0\\[/tex]

So x values of 3 and 6 will make this statement true.

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.

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

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.
