Step-by-step explanation:

Answer:

k = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The equation of proportionality is

y = kx ← k is the constant of proportionality

To find k use any coordinate point lying on the graph

Using (12, 6 ), then

6 = 12k ( divide both sides by 12 )

k = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]

x = 47°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the given angles from 180 for x

x = 180° - (31 + 102)° = 180° - 133° = 47°

Answers

Answer: x=36 degrees

Step-by-step explanation:

Angle EAF and FAB must equal 180 degrees together as all straight lines do. 36 times 3= 108 degrees so 3x=108 degrees. 36 times 2= 72 degrees so 2x=72 degrees. Therefore, 3x+2x=180 degrees.

Answer:

y = 5x + 100

Step-by-step explanation:

Using the x and corresponding y values from the given table.

Let's use the coordinate (0, 100) and (1, 105)

The equation in slope intercept form is expressed as y = mx+c

m is the slope

c is the y-intercept

Slope m = y2-y1/x2-x1

m = 105-100/1-0

m = 5/1

m =5

Get the y intercept

Substitute the slope m = 5 and any point say (0, 100) into the equation

y = mx+c

100 = 5(0) + c

100 = c

c = 100

Get the required equation;

y = mx+c

y = 5x + 100

Hence the equation in slope-intercept form that represents the data is expressed as y = 5x + 100

Jacob and Kerrie are trying to figure out how long they can live off their $84,670 savings if they spend $370 each month. They have each created an equation. Jacob's Equation Kerrie's Equation y = 84,670 + (370x) y = 84,670 − (370x) Which person has the correct equation to model this linear relationship?
A.Kerrie's equation is incorrect, because their spending will increase the amount of their savings. B.Kerrie's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings. C.Jacob's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings. D.Jacob's equation is incorrect, because their spending should be a fixed amount and should not be multiplied.

Answers

Answer:

B.)Kerrie's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings                

Step-by-step explanation:

Given :  Jacob and kerrie are trying to figure out how long they can live off their 84,670 savings if they spend 370 each month.

To Find: Which person has the correct equation to model this linear relationship?

Jacob's equation : y = 84,670+(370x).

Kerrie's equation : y=84,670-(370x).

Since they have 84670 in savings

They spend each month = 370

They spend in x months = 370x

So, spending this amount from saving they left with amount = 84,670-(370x)

Thus Kerrie's equation is correct .

Hence Option B is correct  

B.)Kerrie's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings

Answer:

$2 per Chicken and $9 per Duck

Step-by-step explanation:

the equations for the problem are as follows (x = the value of chickens and y = the value of ducks):

5x + 3y = 55

4x + 3y = 53

if you subtract the equations you would get x = 2, which means the chickens are worth $2 each

If we re-input the x that we now know as 2 and solve one of the equations for y, we will get y = 9

Answer:

If you need the cost of each duck and chicken it would be around 6 dollars per duck or chicken.

Slope of line a is ½. What is the equation of a line that is parallel to line a? Y+½x=2 -2x+y+2=0 2x-2=y -½x+y-2=0

Answers

Answer:

The equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0

Step-by-step explanation:

A line is a polynomial function of the first degree that has the following form:

y = m * x + b

where m is the slope of the line and b is the intercept with the Y axis.  The slope is the inclination of the line with respect to the abscissa axis.

In this case you know that the slope of line a is ½.  

Parallel lines are two or more lines in a plane that never intersect. Two lines are parallel if they have the same slope and different y-intercepts.

You have:

y+½x=2       →       y= -½x +2-2x+y+2=0       →       y=2x -22x-2=y       -½x+y-2=0       →       y=½x + 2

The line that has the same slope as line a is the last one, so the equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0

Identify each value of x that makes 11 + 2x < 13

Answers

Answer:

x < 1

Step-by-step explanation:

This is the answer because:

1) 11 + 2 = 13 and 13 is not less than 13, it is equal to 13. Therefore, x has to equal anything less than 1 because then only inequality statement will be true.

Therefore, the answer is x < 1.

Hope this helps! :D

The value of x that makes 11 + 2x < 13 is x < 1

Given:

11 + 2x < 13

< means less than

11 + 2x < 13

Subtract 11 from both sides

11 + 2x - 11 < 13 - 11

2x < 2

divide both sides by 2

x < 2/2

x < 1

x less than 1

Therefore, the value of x that makes 11 + 2x < 13 is x < 1

Answer:

so this uses proportions.

you need to find the side BF which is proportional to the side BF.

You do:

9/6=x/42

and cross multiply

9*42=6*x

378=6x

divide by 6 on both sides

x=63

the answer is 63

Answer:

These are similar triangles.

By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original

Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:

This means that BF/FE = BC/CD=FC/ED

The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48

BE=BF+FE; BE=9+?

if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE

1x9=9, 7x9=63

63=BE

Ed wants to build a small 800 square foot cabin on a lot that is 80 feet deep. If the building sideyard setbacks are 20 feet and the cabin is 20 feet wide, what is the square footage of the lot

Answers

Answer:

4800 ft²

Step-by-step explanation:

Given that :

Area of cabin = 800 ft²

Width of cabin = 20 feets

Side yard setback of building = 20 feets

Depth of lot = 80 feets

The cabin is a rectangle :

Area of rectangle = Length * Width

800 = length * 20

Length = 800 / 20 = 40 feets

Hence,

Width of lot = side yard + Width of cabin = (20 + 20) = 40 feets

Length of lot = depth +. Length of cabin = (80 + 40) = 120 feets

Area of lot = Length of lot * width of lot

Area of lot = 120 ft * 40 ft = 4800 ft²

Noel Magee purchased a micro-cut shredder at a sale price of $179.99. The regular selling price is $199.99. He also purchased a photo-smart printer at 25% off the regular price of $499.99. A. What is the markdown on the shredder? B. What is the markdown on the printer?

Answers

Answer:

a) 10% off or $20 off

b) 25% off or $124.99 off

Step-by-step explanation:

In order to find the markdown on the shredder we simply need to divide the sale price by the original price. Once we have that we subtract that decimal from 1 and multiply by 100 to get the markdown percentage. We can also subtract the original price from the sales price to get the markdown dollar value.

179.99 / 199.99 = 0.899

(1 - 0.899) * 100 = 10%

199.99 - 179.99 = $20

Now, for the printer we are provided the markdown perentage so to find the markdown dollar value we need to divide the perentage by 100 to turn it into a decimal and multiply that decimal by the regular price of the printer. We can also subtract the markdown dollar value from the original price to get the sale price...

25% / 100 = 0.25

0.25 * 499.99 = 124.99

499.99 - 124.99 = $375
