Explanation

h(x)=x-43

Use substitution

y=x-43

Interchange the variables

x=y-43

Swap the sides

y-43=x

Move the constant to the right

y=x+43

Use substitution

h^-1(x)=x+43

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given function,

f(x) = 10x + 8

Time spent working x = 7:00 PM - 2:30 PM

x = 4.50 hour

f(4.30) = 10(4.50) + 8

f(x) = $53

Hence "The earnings of Jack by the function assuming x as time spent from 2.30 PM will be $53".

To raise money for homecoming the student council sold a total of 240 tickets to a basketball game the number of adult tickets sold was 2 times the number of student tickets based on this information would it be reasonable for the student council to have sold 160 student tickets and 80 adult tickets

Answers

Answer:

no

Step-by-step explanation:

because the number of student tickets 160 is higher than the number of adult tickets 80 and the information tells us that the adult tickets were twice the amount of student tickets sold. If the numbers were swapped to be adult=160 and student=80 then it would be correct.

beyond 500 minutes. Which pair of equations could Tina use to decide on the least costly plan for her
usage? Assume Tina always uses more than 500 minutes per month
(a) c = 39.95 + 0,10m - 300)
(b) c = 39.95 + 0.1(m - 500)

Answers

Answer:

2 radians

Step-by-step explanation:

The ratio of the arc length to the circumference is the same as the measure of angle AOB in radians to 2pi. 2pi radians is a full circle. We can now construct an equation, with x being our answer.

[tex]\frac{6}{6\pi } =\frac{x}{2\pi } \\\frac{1}{\pi } =\frac{x}{2\pi }\\1=\frac{x}{2} \\2=x[/tex]

First, we try to simplify both sides. Next, we multiply both sides by pi. Then, we multiply both sides by 2. Finally, our answer is 2, so 2 radians.

The sum of 2 times a number and 8 is 7

Answers

Answer:

The number is -1/2

Step-by-step explanation:

Let x be the number

2x+8 = 7

Subtract 8 from each side

2x+8-8 = 7-8

2x = -1

Divide each side by 2

2x/2 =-1/2

x = -1/2

The number is -1/2

Answer:

2x + 8 = 7

x = -1/2

Step-by-step explanation:

"a number" can be signified by a variable.

So 2 times a number would give you 2x

And 8 would mean to add 8.

Is 7 means the end result is 7.

So 2x + 8 = 7

x = -1/2
