Answer:

f^-1(x) = 1 -(x/3)

Step-by-step explanation:

To find the inverse function, solve for y:

x = f(y)

x = -3y +3

x/-3 = y -1 . . . . divide by -3

1 -(x/3) = y . . . . add 1

The inverse function is ...

f^-1(x) = 1 -(x/3)

f^-1(x) = (3-x)/3

HURRRRYYYYYYY PLEASE Write the equation of the line that passes through the points (-8,-1) and (5,−7). Put your answer in full

Zinaida [17]

Answer:

y + 8 = 2x + 2

Step-by-step explanation:

Use the points given to find the slope. Divide the difference in y-values by the difference in x-values.

(-1) - (-7) = 6

5 - (-8) = 3

6/3 = 2

The slope is 2.

Now, pick one of the points to put in point-slope form. It doesn't matter which. You will get the right answer either way. I will use (-1, -8).

y - y₁ = m(x - x₁)

y - (-8) = 2(x - (-1))

y + 8 = 2(x + 1)

y + 8 = 2x + 2

Based on the calculations, all of the numbers belong to this arithmetic sequence.

<h3>How to calculate an arithmetic sequence?</h3>

Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:

$a_n = a_1 +(n-1)d$

<u>Where:</u>

d is the common difference.

a₁ is the first term of an arithmetic sequence.

n is the total number of terms.

Next, we would determine the common difference as follows:

d = a₂ - a₁

d = 105 - 99 = 6.

d = a₃ - a₂

d = 111 - 105 = 6.

d = a₄ - a₃

d = 117 - 111 = 6.

Based on the calculations, all of the numbers belong to this arithmetic sequence.

A canoe requires 8 hours of fabrication and a rowboat 5 hours. The fabrication departments has at most 107 hours of labor availa

Elina [12.6K]

Answer: A

Step-by-step explanation: Canoe → 8h →X

Rowboat → 5h → Y

Fabrication department has at most 107, which means it need to be <u>less</u> than 107 hours.

This way, the amount of time to fabricate X canoes = 8X plus the amount of time to fabricate Y Rowboat = 5Y must be less than 107.

8X + 5Y < 107
