Answer:

Option 4

Step-by-step explanation:

Given function is,

f(x)=2\frac{1}{2}-3\frac{1}{3}x

Steps to get the inverse of the given function,

Step 1,

Convert the function into equation,

y=2\frac{1}{2}-3\frac{1}{3}x

Step 2,

Interchange the variables 'x' and 'y',

x=2\frac{1}{2}-3\frac{1}{3}y

Step 3,

Solve the equation for the value of y,

x-2\frac{1}{2}=-3\frac{1}{3}y

x-\frac{5}{2}=-\frac{10}{3}y

-x+\frac{5}{2}=\frac{10}{3}y

-3x+\frac{15}{2}=10y

-\frac{3}{10}x+\frac{15}{20}=y

y=-\frac{3}{10}x+\frac{3}{4}

Step 4,

Convert the equation into inverse function,

f^{-1}x=-\frac{3}{10}x+\frac{3}{4}

For x-intercepts,

Substitute y = 0,

0=-\frac{3}{10}x+\frac{3}{4}

\frac{3}{10}x=\frac{3}{4}

x=\frac{10}{4}

x=\frac{5}{2}

x=2\frac{1}{2}

Therefore, x-intercept of the inverse function is (2\frac{1}{2},0).

Option 4 will be the answer.

Need help with 21-23 you suppose to simplify the expression
lora16 [44]

To solve these problems, we must remember the distributive property. This property states that a coefficient being multiplied by a polynomial in parentheses is equal to the sum of the coefficient times each of the separate terms. Using this knowledge, let's begin with number 21:

-(4x + 17) + 3(7-x)

To begin, we should distribute the negative sign through the first set of parentheses and the coefficient of positive 3 through the second set of parentheses.

-4x - 17 + 21 - 3x

Next, we must combine like terms, or add/subtract the constants terms and the variable terms in order to create a more concise expression.

-7x + 4 (your answer)

Now, we can move on to question 22 and solve it in a similar manner:

7(2n-8) - 4(12 - 8n)

Again, we will distribute the coefficients through the parentheses. However, keep in mind that the coefficient in front of the second set of parentheses is actually a NEGATIVE 4, so we must distribute the negative as well.

14n - 56 - 48 + 32n

Next, we will combine like terms (add the n terms together and subtract the constant terms).

46n - 104

Now, we can solve problem 23:

8 + 2(5f - 3)

We will again distribute through the parentheses:

8 + 10f - 6

Combine like terms after that:

10f + 2

Therefore, your answers for the three problems are as follows:

21) -7x + 4

22) 46n - 104

23) 10f + 2

Hope this helps!

T=pd/2x<br><br><br><br>solve for X<br><br>i always get confused when theirs more then one letter
Ainat [17]
When there's more than one letter, and you just have to solve for one variable, you can just solve it like you would any other equation. Treat the other variables like numbers and add, subtract, multiply, and divide them to both sides of the equation in order to isolate the variable you want to solve for.

t= \frac{pd}{2x}  \\  \\ t*2x= \frac{pd}{2x}*2x \\  \\ 2tx=pd \\  \\  \frac{2tx}{2t} = \frac{pd}{2t}  \\  \\ x=\frac{pd}{2t}

Please help me out! i have a few more of these questions, about 2
Marysya12 [62]

Step-by-step explanation:

Start with a point on (0,6) This is because the 6 represents the point on the y - axis

Then, move up 1 and 3 to the right; This should result with a point on (3,7)

Keep repeating this to get your line

The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function y=34.95x+6.25, wh
Ber [7]

The function we have is:

y=34.95x+6.25

This is a linear function.

We can find the slope (the rate of change) of this function, by comparing it to the general slope-intercept equation:

y=mx+b

Where m is the slope (rate of change) and b is the y-intercept of the line.

By comparison, we see that m an b are:

\begin{gathered} m=34.95 \\ b=6.25 \end{gathered}

Since we are asked for the value of the rate of change, the answer is the value of m:

\text{rate of change=34.95}

which is option A.

Answer:

A. 34.95
