Step-by-step explanation:

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

Answer:

The answer to your equation would be 1.5.

Step-by-step explanation:

The common ratio if there exists one can be found by choosing a term and dividing by its previous term

So does 12/8=18/12=27/18? Put each into the calculator. If they are equal fractions then this sequence is geometric and has a common ratio.

Each of the fractions are equal to 1.5.

Therefore the commom ratio is 1.5.

First Graph Description

Step-by-step explanation:

A linear function shows as a straight line.

The first graph description describes a straight line.

The second, third, and fourth graph description says that either the line is curved, or that it is a parabola. A parabola is not linear.

A coordinate plane is shown with a line that starts to the left of the y-axis, passing through -1 comma 10, then curving right to pass through the y-axis 7, then curving down to pass through the x-axis at 2

A coordinate plane is shown with a parabola opening downward in an upside-down U shape. The base of the parabola sits at the origin and continues downward on both sides of the y-axis

A coordinate plane is shown. A wavy line begins along the x-axis and moves in intervals downward and back up, dipping down to y equals negative 1 and up to y equals 1.

Answer:

Olivia's puppy, it weighed 5 pounds.

Step-by-step explanation:

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

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:

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

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

11 + 2x - 11 < 13 - 11

2x < 2

x < 2/2

x < 1

x less than 1

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

Step-by-step explanation:

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.

I'm not completely sure tho sorry.

Answer:

x=8°

y=29°

Step-by-step explanation:

vertically opposite angles are equal

so 5x+9°=y+20°

therefore 5x-y=11°

Alternate angles are equal

so 4x+17°=y+20°

therefore 4x-y=3°

equation 1....... 5x-y=11°

equation 2......4x-y=3°

using elimination method x=8°

y=29°

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]

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

Answer:

C: <-28,-25>, etc.

Step-by-step explanation:

The vector from A to B is (-28, -25) and the distance between A to B is 3754 meters.

One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related. They can answer geometrical problems because it gives them geometrical aspects of algebra. In this area of geometry, a pair of ordered numbers is used to describe the location of points on a plane.

As per the given data:

Coordinates of school A =  (7, 12)

Coordinates of school B = (-21, -13)

Scale of the map is 1 unit = 100 m

For vector representing the path A to B:

Final - Initial coordinates

= (-21 - 7, -13 - 12)

= (-28, -25)

Distance between A and B:

Distance formula = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

= [tex]\sqrt{(-21 - 7)^2 + (-13 - 12)^2}[/tex]

= 37.54 units {1 unit = 100 m}

= 3754 meters

Hence, the vector from A to B is (-28, -25) and the distance between A to B is 3754 meters.
