The slope of the line will be equal to 1.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.

The slope of the line will be calculated by using the formula below:-

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

The given points are:-

Choose (x1, y1)

X₁= 2 y₁= -5

Identify (x2, y2)

X₂= 7 y₂= 1

Apply the slope formula:-

m= ( y₂ - y₁ ) / ( x₂ - x₁ )

m= 1-(-5)/7-2.

m= ( 5 / 5 )

m = 1

Therefore, the slope of the line will be equal to 1.

I am going to show you how easy this is. Once you understand, you will be able to do this forever.

:

Assuming the side of the rectangle are (L) length and (W) width, the perimeter:

2L + 2W = 234

:

"the rectangle is twice as long as it is wide,", the equation for this statement:

L = 2W

:

In the first equation, we can replace L with 2W, then we have

2(2W) + 2W = 234

4W + 2W = 234

6W = 234

Divide both sides by 6

W = 234%2F6

W = 39 meters is the width

:

Remember it said the length is twice the width, therefore:

L = 2(39)

L = 78 meters is the length

:

:

Check this by finding the perimeter with these values

2(78) + 2(39) =

156 + 78 = 234

Answer:

a: given

b: multiplication property of equality

c: distributive property

d: simplified

e: addition property of equality

f. division property of equality

Step-by-step explanation:

step a will always be given because it is starting equation. step b is multiplication property because everything is multiplied by two so you don't have to deal with decimals. step c is distributive because you distribute the -5s in the parentheses. step d is simplified because they combined like terms and nothing changed sides. step e is addition property because you added 5x to both sides. step f is division property because -7 is divided from each side.

Answer:

n=2

Step-by-step explanation:

4(5n-7)=10+2

1) First, distribute (multiply out 4)

20n-28=10+2

2) Combine like terms (add 10 and 2)

20n-28=12

3) Isolate the variable (Add 28 to 12)

20n=40

4) Isolate the variable (Divide by 20)

Answer:

x = 13

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{DC}{DU}[/tex] = [tex]\frac{CB}{UT}[/tex] , substitute values

[tex]\frac{11x-13}{60}[/tex] = [tex]\frac{169}{78}[/tex] ( cross- multiply )

78(11x - 13) = 10140 ( divide both sides by 78 )

11x - 13 = 130 ( add 13 to both sides )

11x = 143 ( divide both sides by 11 )

x = 13

Answer:

Pongamos los datos

supongamos que la sala costo x

si la sala costo x, el comedor costo el doble, osea 2x

luego dice que la sala costo el triple de la mesa, si la sala costo x, la mesa costo x/3

ahora reemplazamos: dice que todo costo 35000

x + 2x + x/3 = 35000

3x/3 + 6x/3 + x/3 = 35000

10x/3 = 35000

10x= 105000

x = 10500

reemplazamos todos los datos

la sala costo x, entonces la sala costo 10500

el comedor costo 2x, entonces 2(10500) = 21000

la mesa costo x/3, entonces 10500/3 = 3500

The y-intercept is [tex]y=\frac{2}{5} x-4[/tex]

Step-by-step explanation:

Polynomial = (2x² - x + 3)(x - 2) + 4 = 2x³ - 5x² + 5x - 2. (B)

Solution:

[tex]-0.5[/tex]

Steps:

[tex](4x - 1) - 3x = - (x + 2)[/tex]

Start with the left side and combine like terms

[tex]4x-1-3x=-(x+2)\\[/tex]

Combine [tex]4x[/tex] and [tex]-3x[/tex]. After doing this, you would have [tex]x[/tex] because 4-3 = 1

[tex]x-1 =-(x+2)[/tex]

Then, you can distribute the negative on the right side

[tex]-(x+2) = -(x)+-(2) = -x-2[/tex]

You would end up with

[tex]x-1=-x-2[/tex]

Add x to each side.

[tex]2x-1=-2[/tex]

Add 1 to each side

[tex]2x=-1[/tex]

Divide each side by 2 to simplify.

[tex]x=-1/2\\x = -0.5[/tex]

Answer:

Tommy's band won 5 awards, Ali's band won 8 awards and Jack's band won 10 awards.

Step-by-step explanation:

Let the number of awards Tommy won be x.

Number of awards Ali won -> x+3

Number of awards Jack won -> 2x

[tex]x+x+3+2x=23[/tex]

[tex]4x+3=23[/tex]

Subtract 3 from both sides:

[tex]4x+3-3=23-3[/tex]

[tex]4x=20[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4}=\frac{20}{4}[/tex]

[tex]x=5[/tex] (Tommy)

[tex]5+3=8[/tex] (Ali)

[tex]5\times2=10[/tex] (Jack)

Answer: Tommy won 5 awards. Ali won 8 awards. Jack won 10 awards.

Step-by-step explanation:

First give each person a variable:

Tommy = y

Ali = a

Jack = x

Then figure out the equations:

Tommy won 3 less awards than Ali, so the equation would be (y = a - 3).

Jack won twice as many awards as Tommy, so the equation would be (x = 2y)

All three won a total of 23, so that would be (23 = y + x + a)

Next, plug in (2y) into the (x) of (23 = y + x + a)

This would result in (23 = 3y + a)

Then you would plug in (a - 3) into (y)

This would result in (23 = 4a - 9)

Solve for a: (a = 8)

Now that you know (a = 8), plug that into the first equation (y = a - 3) to find (y).

Answer: (y = 5)

Use (y = 5) and plug it into the second equation (x = 2y) to find (x)

Answer: (x = 10)

Answers:

a = 8

Answer:

2.7×10

Step-by-step explanation:

Basically the number 27 has to be in between the numbers 0 and 10.

So to do that you have to divide 27 by 10 until it is between 0 and 10 which is then 2. 7,

And to get the 10 you have to count how many times you had to divide 27 by 10 to get which is 1 so you leave it as ten so the answer you get is

2.7 x 10

Answer:

Step-by-step explanation:

square root of 729= 9

9×9=81

Answer:

Step-by-step explanation:

Formula of Volume= [tex]a^{3}[/tex] - a = side

Therefore since the volume is given you just need to find the side.

729=[tex]a^{3}[/tex] = [tex]\sqrt[3]{729}[/tex] = a

            = 9 = a

Now you know that 9 is the side, so using that find the area of one face-

Area of a square= 9 x 9 = 81[tex]cm^{2}[/tex]

-1=p

Answer:

1.515 = 14* 1.56 + 18*x/(32)

0r, 18x= 1.515*32 - 14*1.56

or, 18x= 26.64

x= 1.48

Step-by-step explanation:

Answer:

mean height of girls = 1.48 m

Step-by-step explanation:

Find the sum height of 32 students.

Sum of the height of 32 students = 32 * mean of 32 students

                                                   = 32 * 1.515

                                                   = 48.48 m

Sum of the height of 14 boys = 14 * mean of 14 boys

                                           = 14 * 1.56

                                           = 21.84

Number of girls = 32 - 14 = 18

Sum of the height of 18 girls =  48.48 - 21.84 = 26.64 m

Average of the height of 18 girls = 26.64 ÷ 18

                                                      = 1.48 m

Step-by-step explanation:

Answer:

Happy paws

y = 20 + 4x

Woof watchers

y = 9 + 5x

x = 11 hours

Step-by-step explanation:

Let

Number of hours = x

Total cost = y

Total cost = fixed cost + variable cost

The equations are:

Happy paws

y = 20 + 4x

Woof watchers

y = 9 + 5x

solve the equation to find for how many hours the total cost of the services is equal.

Equate total cost of both services

20 + 4x = 9 + 5x

Collect like terms

20 - 9 = 5x - 4x

11 = x

x = 11 hours

Check:

Happy paws

y = 20 + 4x

= 20 + 4(11)

= 20 + 44

= 64

Woof watchers

y = 9 + 5x

= 9 + 5(11)

= 9 + 55

= 64

Answer:

Here we have the domain:

D = 0 < x < 1

And we want to find the range in that domain for:

1) y = f(x) = x

First, if the function is only increasing in the domain (like in this case) the minimum value in the range will match with the minimum in the domain (and the same for the maximums)

f(0) = 0 is the minimum in the range.

f(1) = 1 is the maximum in the range.

The range is:

0 < y < 1.

2) y = f(x) = 1/x.

In this case the function is strictly decreasing in the domain, then the minimum in the domain coincides with the maximum in the range, and the maximum in the domain coincides with the minimum in the range.

f(0) = 1/0 ---> ∞

f(1) = 1/1

Then the range is:

1 < x.

Notice that we do not have an upper bound.

3) y = f(x) = x^2

This function is strictly increasing, then:

f(0) = 0^2 = 0

f(1) = 1^2 = 1

the range is:

0 < y < 1

4) y = f(x) = x^3

This function is strictly increasing in the interval, then:

f(0) = 0^3 = 0

f(1) = 1^3 = 1

the range is:

0 < y < 1.

5) y = f(x) = √x

This function is well defined in the positive reals, and is strictly increasing in our domain, then:

f(0) = √0 = 0

f(1) = √1 =1

The range is:

0 < y < 1
