Answer:

f= −x+3

     7x

Step-by-step explanation:

fx       =  −1          3

x        7     x+  7

-------------------------

x                 x

f= -x+3

       7x

f= -x+3

       7x

Answer:

A.

Step-by-step explanation:

f(x) = (3-x)/7

First we find x in terms of f(x:-.

7f(x) = 3 - x

x + 7f(x) = 3

x =  3 - 7f(x)

Now we replace x by f-1(x) and f(x) by x:

f-1(x) = 3 - 7x.

Answer:

4 times bigger

Step-by-step explanation:

1. The area of an object dilated by a scale factor (SF) will be equal to (SF)^2.

2. For example, let's say the base and height of Triangle A is 4 and 8. The area would be 16 units squared. The base and height of Triangle B would be 8 and 16. The area would be 64 units squared.

3. As you can see from the aforementioned example, the SF (2) was squared  and then multiplied by 16 to get 64.

Therefore, Triangle B's area is 4 times bigger than Triangle A's area.

Answer: I think this is how we do it but i am not sure the answer is 48

Step-by-step explanation:

if the price increase by 3/4 then that mean it total will be 7/4 as 4/4 is it original price add so 7/4=84/x 84x4 is 336 336 divide by 7 is 48 to check 48 x 7/4 or 48 x 3/4 and add 48 if u math is correct than u should get 84

Considering the situation given, it is found that:

At the null hypothesis, we test if they average the same amount of trouble hours as last year, that is, of 2000 trouble hours, thus:

Using easy Math Skillz

Answer:

Step-by-step explanation:

1. p║ q

50+130 = 180

If the same side interior angles are supplementary angles then the lines are parallel.

2. p║ q

70 = 70

If the corresponding angles are congruent the lines are parallels.

4. p║ q

x = x

If alternating exterior angles are congruent then the lines are parallel.

5. we do not know if p is parallel with q

We have given that 2 vertical angles are congruent yet that is not enough to tell us about the relation between the 2 lines.

7. For the lines p and q to be parallel we need the corresponding angles 3x and 45 to be congruent so therefore equal in measure.

3x= 45 , divide both sides by 3

x= 15

For x = 15 the p║ q

8. For the lines p and q to be parallel we need the corresponding angles 120 and (2x+10) to be congruent so therefore equal in measure.

2x+10 = 120, subtract 10 from both sides

2x = 110, divide both sides by 2

x = 55

For x = 55 the p║ q

Answer:

52 ft.

Step-by-step explanation:

In this case, we need to calculate a perimeter, which is the sum of all sides of the rectangle.

So, rectangles has opposite sides equal, therefore, the perimeter should be:

; having L as the larger side.

Hence, the strip of wallpaper needs to be as least 52 ft.

Answer:

the amount of interest is $100.80

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6.3%/100 = 0.063 per year,

then, solving our equation

I = 400 × 0.063 × 4 = 100.8

I = $ 100.80

The simple interest accumulated

on a principal of $ 400.00

at a rate of 6.3% per year

for 4 years is $ 100.80.

Answer:

3

Step-by-step explanation:

There are 3 because only numbers with values higher than 0 are counted, unless there is a decimal.

Becuase there is no decimal at the end of this number, there are only 3 counted. Those counted are 1 2 and 9, and all of the 0s dont count.

If there was a decimal at the end this number, it would have been 12

Answer:

The width is: 11

The length is: 2

Step-by-step explanation:

The width is 5 feet longer than 3 times the length so

If the length is 2: 2 x 3 times = 6 plus the five = 11

The area of a rectangle is a = the width x the lenght

So 2 x 11 = 22 that is the area.

Answer:

x= -1/23

Step-by-step explanation:

Answer:

1/3 = 2 2/3 eighths.

Step-by-step explanation:

There are 2(2/3) eights in 1/3.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Eighths = 1/8

Now,

(1/8)x = 1/3

Solve for x.

x = 1/3 x 8/1

x = 8/3

x = 2(2/3)

Thus,

There are 2(2/3) eights in 1/3.

Answer:

x=36

Step-by-step explanation:

first take six away from both sides to get 3/4x=27

then divide 27 by the numerator 3 to get 9. Then multiply 9 by the denominator 4 to get 36. So 3/4 of 36=27+6=33

3/4x+6=33

We move all terms to the left:

3/4x+6-(33)=0

Domain of the equation: 4x!=0

x!=0/4

x!=0

x∈R

We add all the numbers together, and all the variables

3/4x-27=0

We multiply all the terms by the denominator

-27*4x+3=0

We multiply elements

-108x+3=0

We move all terms containing x to the left, all other terms to the right

-108x=-3

x=-3/-108  

x=1/36
