Find the equation of the line.
Use exact numbers.
y = __x+__

Answer:

Yes, the cost y in dollars and the amount of yogurt  are proportional.

The equation is: y = 0.08x

Step-by-step explanation:

1. If y varies directly as x, you can write it as following: y = kx

Where k is the constant of proportionality.

2. Let's calculate the value of the constant of proportionality. If y = 2.56 and x = 32, you have:

y = kx

k = y/x

k = 2.56/32

k = 0.08

3. Then, the equation is: y = 0.08

4. Let's verify if they are directly proportional. Substitute  which is the amount of yogurt bought by Jonah. The result must be $0,48:

y = 0.08 (6)

y = 0.48

5. They are directly proportional.

There are 3 numbers on the cube greater than 3 ( 4, 5, & 6)

This means he has a 3/6 = 1/2 chance of doing that.

He has a 1/2 chance of getting tails on the coin.

The probability of doing both would be the probability of the cube roll x the probability of the coin toss:

1/2 x 1/2= 1/4

The answer is 1/4

Answer:

c  =  125  f

Step-by-step explanation:

Let´s call points  A ( home plate )  B (pitcher´s place ) and C ( outfielder place)

these three points form a triangle in which according to cosine law, one side of a triangle c  can be calculated by the equation:

c²  =  a²  +  b²  - 2a*b*cos∡a,b

a and  b are the other sides of the triangle and ∡a,b is the angle between sides a and b

All distances are in feet then the distance between  outfielder and pitcher  (c) is in feet:

c² = (43)²  +  ( 162)²  - 2*(43)*(162)*cos 27°            cos 27°  = 0,891

c²  = 1849 +  26244 - 12413,4

c²  =  15679,6

c = √15679,6

c  =  125  f

Step-by-step explanation:

Kites have perpendicular diagonals, two pairs of congruent angles and sides.

Required measures:

The angles are m∠1 =m∠2 =m∠3 =m∠4 = 90 degrees.

m∠9=m∠7 =m∠8= m∠10 = 53 degrees.

m∠5 = m∠6 =37 degrees

Let us find the angles.

m∠1 , m∠2, m∠3 and m∠4 are right angles.

m∠1 =m∠2 =m∠3 =m∠4 = 90 degrees.

Now let us find m∠9.

By angle sum property, the sum of three angles is 180 degrees.

m∠1 + 37 + m∠9 =180

37+90+m∠9=180

127+m∠9=180

m∠9=180-127

m∠9=53

m∠9=m∠7 = 53 degrees.

Now let us find m∠6.

53+90+m∠6=180

143+m∠6=180

m∠6=37 degrees.

m∠5 = 37 degrees as it is congruent to m∠6.

Now let us find m∠8.

m∠8 + 90+ 37=180

m∠8 +127=180

m∠8 =53 degrees.

m∠10 = 53 degrees.

Answer:

the distance from the floor below to the top of the bookcase

Step-by-step explanation:

From the question we are given the following

distance from a stage to the floor below = -3

distance from the stage to the top of a bookcase = 3

The distance from the floor below to the top of the bookcase = distance from a stage to the floor below + distance from the stage to the top of a bookcase

The distance from the floor below to the top of the bookcase = -3 + 3

The distance from the floor below to the top of the bookcase = 0

Hence zero represents the distance from the floor below to the top of the bookcase

Answer:

$1,636,363.64

Step-by-step explanation:

let x = total amount of money received

the total amount he received is 100%

Percent remaining after giving a percent of the money to family = 100% - 20% - 25% = 55%

This means that 55% of x = $900,000

To find the value of x, divide both sides by 55% or 0.55

x = $900,000 / 0.55 = $1,636,363.64

Answer:

Y=4X-5

Step-by-step explanation:

The Slope is a positive 4 so you will already have the equation Y=4X and the y-intercept is the Y when X is at the origin. Since the y-intercept is negative you have to subtract from the slope instead of adding. Then you get Y=4X-5.

First off, we can see already that there are congruent symbols in the diagram (the single and double red lines correspond to the other one that looks alike to it)

Step-by-step explanation:

Answer:

Total cost = 983.8

Step-by-step explanation:

Monthly charge = 39.95

One time set up fee = x

Number of months = y

Total cost = x + 39.95y

The total cost of 6 months of service is 264.70.

264.70 = x + 39.95(6)

264.70 = x + 239.7

264.70 - 239.7 = x

x = 25

Total cost = 25 + 39.95y

Write and solve a linear equation to find the total cost for 2 years of service

2 years = 24 months

Total cost = 25 + 39.95y

= 25 + 39.95(24)

= 25 + 958.8

= 983.8

Total cost = 983.8

Step-by-step explanation:

(1)(1) + 5(1) - 6 = 1 + 5 - 6 = 6 - 6 = 0

(-6)(-6) + 5(-6) - 6 = 36 - 30 - 6 = 6 - 6 = 0

Answer:

B

Step-by-step explanation:

Let's solve using factoring.

x²+5x-6=0

5 is the sum of the numbers, while -6 is their product.

Think: which two numbers add up to 5, but when multiplied, equal -6?

Those numbers are -1 and 6.

Now factor the polynomial:

(x-1)(x+6)=0

split into parts:

(x-1)=0

x-1=0

x=1

(x+6)=0

x+6=0

x=-6

So B

Step-by-step explanation:

[tex]y =x[/tex]

If y = -8 — Substitute y = -8 in the equation.

[tex] - 8 = x[/tex]

Therefore, our x is -8 when y = -8

Answer:

x=-8

Step-by-step explanation:

Let's solve your system by substitution.

y=x; y=−8

Rewrite equations:

y=−8; y=x

Step: Solve y=−8 for y:

y=−8

Step: Substitute −8 for y in y=x:

y=x

−8=x

−8+−x=x+−x(Add -x to both sides)

−x−8=0

−x−8+8=0+8(Add 8 to both sides)

−x=8

-x/-1 = 8/-1

x=-8
