Step-by-step explanation:

slope is the average rate of change in a specific interval

we can calculate slope in this case with Δy/Δx or (y2-y1)/(x2-x1)

m=(y2-y1)/(x2-x1)

=(-1-7)/(-3-1)

Answer: 5D = T

Step-by-step explanation:

A dollar spent will give 5 tokens.

The amount of dollars spent therefore will increase the number of tokens you by fivefold.

Formula is therefore:

5D = T

Testing it.

Assume you spent 5 dollars, how many tokens would you have:

5D = T

5 * 5 = 25 tokens

Answer:

87.72%

Step-by-step explanation:

What is the fraction (ratio) 50/57 as a percent value?

49/57 = ? ... 51/57 = ?

Detailed calculations below:

Introduction. Fractions

A fraction consists of two numbers and a fraction bar:

50/57

The number above the bar is the numerator: 50

The number below the bar is the denominator: 57

Divide the numerator by the denominator to get fraction's value:

Val = 50 ÷ 57

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% = p/100 = p ÷ 100.

Calculate fraction's value.

Divide the numerator by the denominator to get fraction's value:

50/57 =

50 ÷ 57 ≈

0.87719298245614

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

Calculate the percent value:

0.87719298245614 =

0.87719298245614 × 100/100 =

(0.87719298245614 × 100)/100 =

87.719298245614/100 =

87.719298245614% ≈

87.72%;

In other words:

1) Calculate fraction's value.

2) Multiply that number by 100.

3) Add the percent sign % to it.

Answer:

:: written in two ways ::

Not rounded:

50/57 = 87.719298245614%

Rounded to maximum 2 decimals:

50/57 ≈ 87.72%

Signs: % percent, ÷ divide, × multiply, = equal, / fraction bar (division bar), ≈ approximately equal;

Answer:

Point-Slope: y+1=-5/7(x-5)

Slope Intercept: y=-5/7x+ 2 4/7

Standard: -5x+7y=18

Step-by-step explanation:

Slope: -5/7

Point slope is when the equation is in y-y1=m(x-x1) form.

I used the point (5,-1) but it really doesn't matter which one

Substitute it into (x1,y1)

y--1=-5/7(x-5)

y+1=-5/7(x-5) **2 minus signs is equal to 1 plus sign**

Slope-intercept is when the equation is in y=mx+b form.

y=-5/7x+b

To solve for b, plug in one of the points (again, I choose to use (5,-1)

(-1)=-5/7(5)+b

-1=-25/7+b is equal to asking -1=-3 4/7+b

b=2 4/7

Standard form is when it is in Ax+By=C

We'll covert from slope intercept to standard: y=-5/7+ 2 4/7

y=-5/7x+ 2 4/7 is the same as y=(-5/7x+ 18/7)

7y=5x+18 **Multiply both sides by 7, the common denominators**

-5x+7y=18 **Subtract 5x from both sides**

Sorry it took it while to get everything down but I hope this helps~

Answer:

x=2

y=3

Explanation

1. Solve x + 2y = 8 for x:

x + 2y = 8

x+2y + − 2y = 8 + −2y(Add -2y to both sides)

x = −2y + 8

2. Substitute −2y + 8 for "x" in 5x − 2y =4

5x − 2y = 4

5 (−2y + 8) − 2y =4

−12y + 40 = 4 (Simplify both sides of the equation)

−12y + 40 + −40 = 4 + −40(Add -40 to both sides)

−12y = −36 (Divide both sides by -12)

y = 3

3. Substitute 3 for "y" in x= −2y + 8

x = −2y + 8

x = (−2) (3) + 8

x = 2 (Simplify both sides of the equation)

Answer:

x = 2 and y = 3

Answer:

320 pesos

Step-by-step explanation:

Un 20% de descuento en formato decimal es 0.20. La totalidad de la bicicleta es representada como 100% o 1 y nosotros queremos saber el precio despues del descuento que seria

100% - 20% = 80% o 0.80

Ahora simplemente multiplicamos este decimal por el valor original de la bicicleta para saber el precio descontado...

400 * 0.80 = 320 pesos

Answer:

x = 6

Step-by-step explanation:

The Pythagorean Theorem states that a² + b² = c². In this case, c would be the hypothenuse or the longest side, which is 10. 8 can be either a or b.

a² + b² = c²

a² + 8² = 10²

a² + 64 = 100

a² = 36

a = √36

a = 6

So, x = 6.

Hope that helps.

Answer:

28+8=24

61=12-6

Step-by-step explanation:

Subtract 8 from both sides of the equation.

2x+8=24

2x+8-8=24-8

Simplify

2x=16

Divide both side of the equation by the same term

2x/2 16/2

Simplify

x=8

Subtract the numbers

6x=12-6

6x=6

Divide both side of the equation by the same term

6x/6 6/6

Simplify

x=1

hope it helps took a long time to do lols

Answer:

Answer: 375

Step-by-step explanation:

2/3 of x= 250

250 x 3=750

750//=375

They need a minimum of 375 students in order to keep the venue,

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, So far two-thirds of the seniors bought prom tickets. if they need a minimum of 250 people to attend in order to keep the venue.

Assuming they need a minimum of x people.

∴ (2/3)x = 250.

2x = 750.

x = 375.

Step-by-step explanation:

Answer:

f(x) = 3x

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)

m = [tex]\frac{3-0}{1-0}[/tex] = 3 , then

y = 3x ← is the equation of the graphed line

Answer:

m (slope) = 664

Step-by-step explanation:

Formula:

m (slope) = y1-y2/x1-x2

m = 16570 - 21226 / 1982 - 1986

= -4,656 / -4

= 664
