Which equation could be used to create the graph? y=x−2 y=x−4 y=x3 y=3x

Answer:

see below

Step-by-step explanation:

27.

We can use ratios to solve

152 dollars     532 dollars

---------------- = ----------------

4 days              x days

Using cross products

152x = 4*532

152x =2128

Divide each side by 152

152x/152 = 2128/152

x =14

14 days

29.

1 inch        2/3 inches

------------ = ----------------

6.5 ft          x ft

Using cross products

1x = 2/3 * 6.5

x = 4.333333

c = 4 1/3 ft

Answer:

[tex]\Large \boxed{\mathrm{27. \ 14 \ days}} \\ \\ \Large \boxed{\mathrm{29. \ 4 \frac{1}{6} \ feet}}[/tex]

Step-by-step explanation:

(27)

We can apply ratios to solve for the problem.

Let x be the missing value.

[tex]\displaystyle \frac{152}{4} =\frac{532}{x}[/tex]

Cross multiply.

152 × x = 532 × 4

152x = 2128

Divide both sides by 152.

x = 14

(29)

We can apply ratios to solve for the problem.

Let x be the missing value.

[tex]\displaystyle \frac{1}{6\frac{1}{4} } =\frac{\frac{2}{3} }{x}[/tex]

Cross multiply.

1 × x = 6 1/4 × 2/3

x = 6 1/4 × 2/3

Convert mixed fraction to improper fraction.

x = 25/4 × 2/3

x = 50/12

Simplify.

x = 25/6 or 4 1/6

Answer:

[tex]\huge\boxed{ 12\ people}[/tex]

Step-by-step explanation:

At least 6 hours means that the people took at least 6 hours and at most any number that is greater than 6. Here the greatest no. is 10.

So, the range for this will be 6-10

No. of People who sleep for 6-8 hours = 9

No. of People who sleep for 8-10 hours = 3

No. of People who sleep for 6-10 hours = 9+3

=> 12 people

Answer:

Step-by-step explanation:

1 sq. meter = 10.7639 sq.feet

15.8 sq. m = 15.8 * 10.7639

                 = 170.06962 sq. feet

Answer:

Skew lines

Step-by-step explanation:

Skew lines are two straight lines in three dimensional space that are neither parallel nor do they intersect Examples of skew lines are the front sidewalk and a line that goes along one of the top edges of the house, or lines that connecting opposite edges of a regular tetrahedron

Other examples of skew lines can be found in non co-planar non parallel, parts of a bridge.

Answer:

125 kilometres does 1 1/2 decimetres represent

Step-by-step explanation:

Given

3 cm = 25 KM  (Representative)

we have to find value of 1 1/2 decimetre

1 1/2 decimetre = (1*2+1)/2 decimetre = 3/2 decimetre

we know

1 decimetres = 10 cm

3/2 decimetres = 3/2 *10 cm = 15 cm

thus, we have to find 15 cm on the 3 cm = 25 KM map.

3 cm = 25 KM

1 cm = 25/3 KM

15 cm = 15*25/3 KM = 125 KM

Thus,

125 kilometres does 1 1/2 decimetres represent

Answer:

1. Mean- 64.43

  Range- 77

2. Mean- 30.42

   Mode- 35

   Median- 20

Step-by-step explanation:

1. Mean- 50+60+48+72+23+98+100= 451

              451 divide by 7= 64.43

   Range- biggest no. - smallest no.     100-23=77

2. Mean- 31+37+35+38+42+23+17+18+35+25+35+29= 365 -->

               365 divide by 12= 30.42

   Mode- most repeated no= 35

   Median- 2 middles-- 23+17=40 then divide by 2= 20.

The correct option is;

C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing

Step-by-step explanation:

In other to solve the equation 4·b + 3 = 11, we have;

By the subtraction property of equality, we have;

Firstly we subtract 3 from both sides gives;

4·b + 3 - 3= 11 - 3

Next we apply the division property of equality, we have;

Both sides of an equation remain equal when we divide both sides of the equation by the same, non-number,

Dividing both sides by 4, gives;

4·b/4 = 8/4

b = 8/4 = 2

The solution to the equation, 4·b + 3 = 11 is b = 2.

The reflection of a point (x, y) across the x-axis is given by the relation;

Coordinate of the pre-image (x, y) [tex]\overset{Reflection \ across \ the \ x-axis}{\rightarrow}[/tex] Coordinate of image (x, -y)

Therefore, we have for the points as follows;

Answer:

x = 13

Step-by-step explanation:

Rearrange: x = 15 + 7 - 9, x = 13

Answer:

X=2

Step-by-step explanation: First 9-7=2 then subtract 2 from both sides and you should be left with X=13

Answer:

n = 4

Step-by-step explanation:

We can expand, getting 10 + 5n = 3n + 18.

Then, combine all like terms, getting 5n - 3n = 18 - 10, which can be rewritten as 2n = 8.

Solve this by dividing both sides by 2, and get n = 4.

Answer: so its n=4

Step-by-step explanation:   This problem will require distribution

5(2+n) = 3(n+6)

10+5n=3n+18

Move all the variables on one side

5n-3n=18-10

2n=8

Divide by 2

n=4

5 ( 2 + n ) = 3 ( n + 6 )

First distribute the 5 and the 3. By doing that, your equation should look like

10 + 5n = 3n + 18 Now, subtract 3n from both sides, this way all the " n " would be on the same side making it easier to solve

By subtracting 3n from both sides the equation would be

10 + 2n = 18 Now subtract 10 from both sides

By subtracting 10 from both sides your equation should be

2n = 8 Divide 2 from both sides

By dividing your equation should look like

n = 4 which is your answer

Answer:

x = 9 and x = -1

Step-by-step explanation:

This equation should be written all on one line:

2(x - 4)^2 = 50

using " ^ " to denote exponentiation.

Dividing both sides by 2 yields

(x - 4)^2 = 25

We must solve for x - 4, and then for x alone:

Taking the square root of both sides, we get:

x - 4 = ±5

which yields two separate solutions:  x = 9 and x = -1

Answer:

Step-by-step explanation:

9.48 as a mixed number in simplest form:

948/100

948/100= 948 ÷ 4/100 ÷ 4

948/100= 948 ÷ 4/100 ÷ 4= 237/25

948/100= 948 ÷ 4/100 ÷ 4= 237/25= 9 12/25

9 12/25 is the mixed number.

Answer:

Step-by-step explanation:

The question lacks appropriate diagram. Find the diagram attached.

Slope is the change in coordinate of the y coordinate to the x coordinate.

Mathematically, slope m = ∆y/∆x

From the diagram ∆y is the same as 3 (along the vertical) while ∆x is the same as 1 (along the horizontal)

m = ∆y/∆x = 3/1

∆y/∆x = 3/1

y/x = 3/1

Cross multiply

y × 1 = 3 × x

y = 3x

Hence the slope of the line is y = 3x

Answer:

Step-by-step explanation:

y/x=3/1 is the first blank

y=3x is the last one

Hi

on a regular dice you have  3 even number  :  2 ;4;6

                                                3  odd number : 1;3;5

so probability to have an odd number is : 3/6 = 1/2

Answer:

1/2

Step-by-step explanation:

On normal six-sided die, there are the numbers: 1, 2, 3, 4, 5, and 6.

The odd numbers are 1, 3, and 5.

There is a [tex]\frac{1}{6}[/tex] chance that you will roll any number specifically. Since you stated 3 numbers, the probability that you will roll any of those three numbers is [tex]\frac{3}{6}[/tex], which is equivalent to [tex]\frac{1}{2}[/tex].

Answer/Step-by-step explanation:

a. % of people who smoke = no. of people who smoke ÷ total no. of people surveyed × 100

Total no. of people who smoke is given = 4 + 36 = 40

Total people surveyed = 200

% of people who smoke = [tex] \frac{40}{200}*100 = \frac{40}{2}*1 = 20 percent [/tex]

a. % of people who do not exercise regularly = no. of people who do not exercise regularly ÷ total no. of people surveyed × 100

Total no. of people who do not exercise regularly = 36 + 134 = 170

Total people surveyed = 200

% of people who smoke = [tex] \frac{170}{200}*100 = \frac{170}{2}*1 = 85percent [/tex]
