But the answer is (D) F-1 (X) = 7x - 3

Step-by-step explanation:

Well took the test and got the answer wrong for the guy on top and took it again and got it right...

The inverse of the function f(x) is equivalent to -

f ⁻¹(x) = 7(3 - x).

Given is the function -

f(x) = 3 - x/7

The given function is -

f(x) = 3 - x/7

we can write -

y = 3 - x/7

Replace [y] and [x], as follows -

x = 3 - y/7

y/7 = 3 - x

y = 7(3 - x)

f ⁻¹(x) = 7(3 - x)

Therefore, the inverse of the function f(x) is equivalent to -

f ⁻¹(x) = 7(3 - x).

Step-by-step explanation:

Answer:

t = 3

Step-by-step explanation:

5t - 4 = 11

5t - 4 + 4 = 11 + 4 (you do the plus 4 to get rid of the -4 and what you do to one side you have to do to the other.)

5t = 15

5t/5 = 15/5 (To get red of the 5 do reverse operation.)

1t = 3 simplified to

t = 3

Hope it helped (brainlyest pls) ;)

Answer:

3

Step-by-step explanation:

5t - 4 = 11

(5 x t) - 4 = 11

5 x 3 = 15

I did the test and got it correct.

Answer:

a = 4

Step-by-step explanation:

1/2a + 3 = 5

combine like terms:

1/2a = 5-3

1/2a = 2

multiply both sides by 2 to cancel out the fraction

a = 4

Answer:

According to the parallel lines theorem, the angle ∠JOP = ∠OPK

Thus, a = 45°.

Now according to the opposite angles theorem, ∠OPK = ∠NPL

thus, x = 45°.

Hey Child.

The answer to this is 1 or 7:

To find the range for the number of measures played to satisfy our solution, we must solve for x using s = 80.

Next, we subtract 50 from both sides of the equation.

Next, we divide both sides of the equation by 10

Next, to eliminate the absolute value bars, we will add a ± sign in front of our s value, 3.

Finally, we add 4 to both sides of our equation giving us 4 ± 3 = x

Separating this into two equations, we get 4 - 3 = x and 4 + 3 = x

Therefore, x, the number of measures of music played, must be either 1 or 7.

Answer: 7 5/7 (the bottom one)

Step-by-step explanation:

30 divided by 2 = 15 (do the same to 42 and get 21)

This then creates the fraction: 15/21

Now, divide this fraction by 3 and get 5/7

Add back in the seven because you aren't dividing the whole number.

Your final answer is now 7 and 5/7 (together: 7 5/7)

Answer:

s ≤ 160

Step-by-step explanation:

To represent a situation that no more Than 160 students are in a a freshman class.

Let the Total number of students in the class = s

Hence, to represent the situation using inequality notation :

s ≤ 160

This means, S is less than or equal to 160

Answer:  3 is the nearest integer.

Step-by-step explanation:

The square root of 12 is between 3 and 4  

9 and 16 are perfect squares. Their roots are 3 & 4 respectively. 12 is about halfway between, so a good approximation would be 3 1/2, but the question asks for the nearest integer, not the nearest rational number.

put the value of f(x) = 0

f(0) = 7(0)-6

=0-6

Step-by-step explanation:

f(x)= 7x - 6

f(x) = 0

7x - 6 = 0

7x = 6

x = 6/7 ? (I think you need to solve for x)

Answer:

Step-by-step explanation:

It will take 6 weeks for the sprout in Jessi's garden to grow 13 cm tall.

Given that,
A sprout in Jessie’s garden is 5 1/5 cm tall and is growing 1 3/10 cm each week. Write and solve equality in order to resolve how many weeks it will take for the plant to be 13 cm tall is to be determined.

In calculation, it deals with number of procedures according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
Let the number of weeks be x, the height after each week be y
According to the question,
y = 5 1 /5 + 1 3/10 x
y = 26 / 5 + 13 / 10x
Now,

y = 13
13 = 26 / 5 + 13 /10x
13/10x = 13 - 26 / 5  
x = 39 × 10 / 5 × 13
x = 3  ×2
x = 6

Thus, it will take 6 weeks for the sprout in Jessi's garden to grow 13 cm tall.

Answer:

63

Step-by-step explanation:

Jason age will be 63 years.

What is an expression?

Expression in math is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

The condition is given as;

'' Jason says that 10 less than one third of his age is 11 years old. ''

Now,

Let age of Jason = x years

Then, By the given condition we formulate;

1/3 x - 10 = 11

Solve for x as;

1/3 x - 10 = 11

Add 10 both side;

1/3 x - 10 + 10 = 11 + 10

1/3 x = 21

Multiply by 3;

x = 63

Thus, Jason age will be 63 years.

Answer:

m∠CEH = 79°

Step-by-step explanation:

From the picture attached,

∠CED and ∠CEH are the pair of linear angles.

Since, pair of linear angles are supplementary angles.

m∠CED + m∠CEH = 180°

101° + m∠CEH = 180°

m∠CEH = 180° - 101°

             = 79°

Therefore, measure of angle CEH is 79°.

Answer:

Price of Adult tickets =$ 13

Price of student tickets =$ 8

Step-by-step explanation:

Lets us represent the price of adult tickets = x

The price of student tickets = y

On the first day of ticket sales the school sold 10 adult tickets and 13 student tickets for a total of $234.

= 10 × x + 13 × y = $234

= 10x + 13 y = 234

The school took in $97 on the second day by selling 5 adult tickets and 4 student tickets.

5 × x + 4 × y = $97

= 5x + 4y = 97

Hence:

10x + 13y = 234......Equation 1

5x + 4y = 97......... Equation 2

We solve by elimination method

Multiply the equation 1 by 5 and equation 2 by 10 which are the coefficient of x

10x + 13y = 234......Equation 1 × 5

5x + 4y = 97......... Equation 2 × 10

50x + 65y = 1170......Equation 3

50x + 40y = 970..... Equation 4

Subtract Equation 4 from Equation 3

25y = 200

y = 200/25

y = 8

Therefore the price of student ticket = $8

Note that

5x + 4y = 97......... Equation 2

5x + 4 × 8 = 97

5x = 97 + 32

5x = 65

x = 65/5

x = 13

Therefore price of adult tickets = $13

Answer:

a

Step-by-step explanation:

just bc it is

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = [tex]\frac{1}{2}[/tex] and (a, b) = (3, - 2) , thus

y - (- 2) = [tex]\frac{1}{2}[/tex] (x - 3) , that is

y + 2 = [tex]\frac{1}{2}[/tex]( x - 3) ← in point- slope form

(b)

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{1}{2}[/tex] , thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (3, - 2) into the partial equation

- 2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = - 2 - [tex]\frac{3}{2}[/tex] = - [tex]\frac{7}{2}[/tex]

y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{7}{2}[/tex] ← in slope- intercept form
