Answer:

y = 1/2x - 2 OR f(n)= 1/2n - 2

Step-by-step explanation:

Start by rewriting with X and Y just for ease:

Swap X and Y's places

Solve for Y

y = 2x+4

x = 2y+ 4

x - 4 = 2y

1/2x - 2 = y

Answer: The area of the actual office space = 18 sq. yards

Step-by-step explanation:

Formula : Image length = Scale factor x original length

Given: A scale drawing of an office space uses a scale of 2 in. : 3 yd.

i.e. scale factor = [tex]\dfrac23[/tex]

The scale drawing has an area of 12 square inches.

i.e.   [tex]\text{12 sq. inches}=\dfrac23\times\text{area of the actual office space }[/tex]

[tex]\Rightarrow\ \text{Area of actual office space}=\dfrac{3}{2}\times12=18\text{ sq. yards}[/tex]

Hence, the area of the actual office space = 18 sq. yards

The value of H is 7 and the the value of K is -2.

Answer:

[tex]F = \frac{9}{5}(C + 32)[/tex]

Step-by-step explanation:

Given

[tex]C = \frac{5}{9}F - 32[/tex]

First, we need to solve for F

[tex]C = \frac{5}{9}F - 32[/tex]

Add 32 to both sides

[tex]C + 32 = \frac{5}{9}F - 32 + 32[/tex]

[tex]C + 32 = \frac{5}{9}F[/tex]

Multiply both sides by [tex]\frac{9}{5}[/tex]

[tex]\frac{9}{5} * (C + 32) = \frac{5}{9}F * \frac{9}{5}[/tex]

[tex]\frac{9}{5} * (C + 32) = F[/tex]

[tex]F = \frac{9}{5} * (C + 32)[/tex]

[tex]F = \frac{9}{5}(C + 32)[/tex]

Next, is to determine the temperature in degrees Fahrenheit

However, this is not stated the degree Celsius equivalent is not stated in your question.

So, I'll assume a value for it.

Assume that C = 23

Substitute 23 for C in [tex]F = \frac{9}{5}(C + 32)[/tex]

[tex]F = \frac{9}{5}(23+ 32)[/tex]

[tex]F = \frac{9}{5}(55}[/tex]

[tex]F = 9 * 11[/tex]

[tex]F = 99[/tex]

Answer:

No, 80/10 turned into a whole number is 8, not -8.

Step-by-step explanation:

To get a whole (1), you need to have 10/10. Since we have 10/10 8 times (80/10) this means we get a whole number of 8, not -8. Therefore, its false. 80/10 is NOT equal to -8

Answer:

The greatest length in feet the twines can be cut into with no twine left over is 4 feet

Step-by-step explanation:

To determine the greatest length a 20 feet long twine and a 12 feet long twine can be cut into such that the pieces are of the same length and no twine is left over, we will find the highest number that can be used to divide 20 and 12 with no remainder. Hence, we will find the Highest common factor (HCF) of 20 and 12.

Factors of 20 are: 1,2,4,5,10, and 20

and the factors of 12 are: 1,2,3,4,6, and 12

The highest common factors of 20 and 12 is 4.

Hence, the greatest length in feet the twines can be cut into with no twine left over is 4 feet.

Answer:

y=3x+8

Step-by-step explanation:

m=3

y-(-1)=3(x-(-3))

y+1=3x+9

y=3x+8

The equation of the line passes through the point  (-3, -1)(and (-4, -4) is y=3x+8.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that line passes through the points (-3, -1)(and (-4, -4)

The slope will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -4 + 1 ) / ( -4 + 3 )

Slope = 3

The y-intercept is calculated as,

y = 3x + c

-1 = 3 x -3 + c

c = 8

The equation of the line will be,

y=3x+8

The minimum number of weeks Clarissa needs to save is 6 weeks.

Step-by-step explanation:

Clarisaa wants to go to  the concert with the luke bryan

Ticket cost=$54.50

Inequality= 25+5w[tex]\geq[/tex] 54.50

upon solving the inequality we get  

5w [tex]\geq[/tex]  54.50-25

5w [tex]\geq[/tex]   29.5

Step-by-step explanation:

Answer:

a. (6 * 50) + (6 * 3)

b. (6 * 40) + (6 * 13)

Step-by-step explanation:

Here, we want to use the distributive property to write equivalent expression .

We can have the given expression as follows;

6 * ( 50 + 3) = (6 * 50) + (6 * 3)

Furthermore, we can write the expression as;

6 * (40 + 13) = (6 * 40) + (6 * 13)

Answer:

3 (5 x - 2) (y - 3)

Step-by-step explanation:

Factor the following:

15 x y - 6 y - 45 x + 18

Hint: | Factor out the greatest common divisor of the coefficients of 15 x y - 6 y - 45 x + 18.

Factor 3 out of 15 x y - 6 y - 45 x + 18:

3 (5 x y - 2 y - 15 x + 6)

Hint: | Factor pairs of terms in 5 x y - 2 y - 15 x + 6 by grouping.

Factor terms by grouping. 5 x y - 2 y - 15 x + 6 = (5 x y - 2 y) + (6 - 15 x) = y (5 x - 2) - 3 (5 x - 2):

3 y (5 x - 2) - 3 (5 x - 2)

Hint: | Factor common terms from y (5 x - 2) - 3 (5 x - 2).

Factor 5 x - 2 from y (5 x - 2) - 3 (5 x - 2):

Answer:

x = 10

x = 27

Step-by-step explanation:

53 and 5x + 3 are vertical angles.

vertical angles are equal.

using that, you can make this equation:

53 = 5x + 3

subtract 3 from both sides of the equation

53 - 3 = 5x + 3 - 3

50 = 5x

divide both sides of the equation by 5

50/5 = 5x/5

10 = x

82 and 3x + 1 are vertical angles.

vertical angles are equal.

using that, you can make this equation:

82 = 3x + 1

subtract 1 from both sides of the equation

82 - 1 = 3x

81 = 3x

divide both sides of the equation by 3

81/3 = 3x/3

27 = x

Answer:

Step-by-step explanation:

slope = M

M= rise / run

rise = Y2-Y1

run = X2 -X1

P1=(X1,Y1) = (3,-3)

P2=(X2,Y2) = (6,9)

M= 9-(-3)  /  6-3

M=12 /3

M=4

the slope is 4

a parallel line will have the same slope

a perpendicular line will have an inverse slope  or 1/4
