For this case, the first thing we must do is define variables.

We have then:

x: number of rides

y: total cost

We now write the equations for each park.

For The Thrill amusement park:

y = 5x + 40

For The Splash water park:

y = 3x + 60

Answer:

A system of equations that could be used to determine the solution where the cost per ride of the two amusement parks, and, is the same is:

y = 5x + 40

y = 3x + 60

Answer:

The square root of 38.

Step-by-step explanation:

The square root of 38 is about 6.16.

The square root of 35 is about 5.91.

The square root of 45 is about 6.70.

The square root of 48 is about 6.92,

So the most reasonable one is the square root of 38, since it is much closer to 6.

Please help me its about Solving by substitution

Len [333]

Step-by-step explanation:

x=y+7

3x+2y=6

so wherever you see X you but y+7

3(y+7)+2y=6

3y+21+2y=6

group like terms

3y+2y=6-21

5y=-15

divide by 5

y=-3

to find x sub the y value in the equation

x=y+7

x=-3+7

x=4

In high school, some students have been confused to believe that 22/7 is already the actual value of π or an acceptable approxim

jarptica [38.1K]

Answer:

Since it has smaller absolute and relative errors, 355/113 is a better aproximation for $\pi$ than 22/7

Step-by-step explanation:

The formula for the absolute error is:

Absolute error = |Actual Value - Measured Value|

The formula for the relative error is:

Relative error = |Absolute error/Actual value|

I am going to consider the actual value of $\pi$ as 3.14159265359.

In the case of 22/7:

22/7 = 3.14285714286.

Absolute error = |3.14159265359 - 3.14285714286| = 0.00126448927

Relative error = 0.00126448927/3.14159265359 = 0.00040249943 = 0.04%

In the case of 355/113

355/113 = 3.14159292035

Absolute error = |3.14159265359 - 3.14159292035| = 0.00000026676

Relative error = 0.00000026676/3.14159265359 = 0.000000085 = 0.0000085%

Since it has smaller absolute and relative errors, 355/113 is a better aproximation for $\pi$ than 22/7

Find the missing value so that the two points have a slope of 3/2 (0,y) and (2,-2)

Harlamova29_29 [7]

Answer:

y = -5

Step-by-step explanation:

To find the slope , we use

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

3/2 = (-2-y)/(2-0)

3/2 = (-2-y)/2

Since the denominators are the same, the numerators have to be the same

3 = -2-y

Add 2 to each side

3+2 = -2-y+2

5 = -y

Divide each side by -1

5/-1 = -y/-1

-5 = y
