Answer:

D

Step-by-step explanation:

Percent =  Part/Whole x 100%

Percent =  1/24 x 100%

Percent =  4% Rounded

Answer:

Firstly

f(x)=3x-2=y then

Interchanging x and y we get

x=3y-2

x+2=3y

y=(x+2)/3

f-1(x)=(x+2)/3

f-1(13)=(13+2)/3

f-1(13)=5

A function is defined as a relation between a set of inputs having one output each.

The inverse of function f(x) = 3x - 2 is:

y = (x+2)/3

A function is defined as a relation between a set of inputs having one output each.

The inputs are called the domain of the function.

The outputs are called the range of the function.

We have,

f(x) = 3x - 2

The inverse of f(x):

step 1:

Put f(x) = y

y = 3x - 2

step 2:

switch x and y

x = 3y - 2

step 3:

solve for y

x = 3y - 2

x + 2 = 3y

y = (x+2)/3

Thus,

The inverse of f(x) = 3x - 2 is y = (x+2)/3

Answer: 2827 cm squared is the answer

Answer: x = -1.8

Step-by-step explanation:

-7 - 12 = -7x + 3 (-4 - x)

-7x + 3 (-4 - x) = -7 - 12

P.S I switched the order cuz I find it easier to solve this way.

-7x + 3 (-4 - x) = -7 - 12

Distribute

-7x - 12 - 3x = - 7 + 13

Add 12 to both sides

-7x - 3x = -7 + 13 + 12

Combine like terms

-10x = 18

Divide both sides by -10

x = -1.8

Answer:

$9000 x 3.2%/Q= $288/Q

13 years = 13*4 Q= 52 Q

=> $288 x 25 Q = $14,976

The account balance be after 13 years is : $ 14,976 + $9,000 = $23,976

Step-by-step explanation:

When three or more numbers are multiplied, the product is the same regardless of  the way in which the numbers are grouped.

Answer:

x = 13.25 kg

y = 6.5 kg

Step-by-step explanation:

Let

Large box = x

Small box = y

4x + 8y = 105 (1)

2x + 3y = 46 (2)

(Multiply (2) by 2 to eliminate x

2x + 3y = 46 (2) ×2

4x + 6y = 92 (3)

4x + 8y = 105 (1)

Subtract (3) from (1)

8y - 6y = 105 - 92

2y = 13

y = 13/2

y = 6.5kg

Substitute y = 6.5 into (2)

2x + 3y = 46 (2)

2x + 3(6.5) = 46

2x + 19.5 = 46

2x = 46 - 19.5

2x = 26.5

x = 26.5/2

x = 13.25 kg

Answer:

x = -5/3

Step-by-step explanation:

3x - 2 = -7

Add 2 to both sides

3x - 2 + 2 = -7 +2

          3x  = -5

Divide both sides by 3

            3x/3 = -5/3

            x = -5/3

The number of paper newsletters the school needed is given by the equation A = 149.5

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of paper newsletters the school needed be A

Now , the equation will be

The percentage of parents who prefers newsletters electronically = 77 %

So , percentage of parents who prefers paper newsletters = 100 % - 77 %

The percentage of parents who prefers paper newsletters = 23 %

The total number of parents = 650

So , the number of paper newsletters the school A = percentage of parents who prefers paper newsletters x total number of parents

Substituting the values in the equation , we get

The number of paper newsletters the school A = ( 23/100 ) x 650

The number of paper newsletters the school A = 149.5

Therefore , the value of A is 149.5

Hence , the equation is A = 149.5

1st hour: -4.5 and 15

2nd hour: -2 and 11

3rd hour: 0.5 and 7

4th hour: 3 and 3

Answer:

after 52/3 hours

temparature will be at -151/3

Step-by-step explanation:

y = -2.5x - 7

y = -4x + 19

-2.5x - 7 = -4x + 19

4x - 2.5x = 19 + 7

1.5x = 26

1.5x = 26

3/2x = 26/1

2/3 x 3/2x = 26/1 x 2/3

x = 52/3

y = -4x + 19

y = -4(52/3) + 19

y = -208/3 + 19

y = -208/3 + 19/1

y = -208/3 + 57/3

y = -151/3
