Okay, so the y-intercept in the graph is 4. In a function, when x=0, the y-coordinate is the y-intercept.

Table #1: (0,3)

Table #2: (0,2)

Table #3: (0,5)

Table #4: (0,4)

Table #5: (0,-7)

5 is the only y-intercept given that is greater than 4, which is the y-intercept of the line in the graph.

Answer: Table #3 (the third table down) represents a linear function with a y-intercept greater than that of the function represented in the graph.

Hope this helps!

The one in the middle you can tell because when x=0 that is the y intercept and the graph had a y intercept of 4 and the middle graph had 5

Please help me with this question below

BabaBlast [244]

Answer:

381 cubic inches

Step-by-step explanation:

To find the volume of the cube, use the volume formula for a rectangular prism V = l*w*h and for a triangular prism V = 1/2 l*w*h.

<u>Rectangular prism</u>

Substitute l = 16, w = 7, and h = 3.

V = 16*7*3 = 336 cubic inches

<u>Triangular prism</u>

Substitute l = 5, w = 3 and h = 6.

V = 1/2*5*3*6 = 45 cubic inches

Together the volume will be 336 + 45 = 381.

Write four different expressions for the perimeter of a pentagon whose sides are all s-2 units long

igor_vitrenko [27]

Answer: The answers are given below.

Step-by-step explanation: Given that all the sides of a pentagon are (s-2) units long. This clearly tells us that the pentagon is a regular one with each side equal to (s-2) units.

We are to write the perimeter of the pentagon in four different expressions.

Let 'P' represents the perimeter of the pentagon.

Since it is a regular pentagon, we can write the perimeter in following four expressions.

P = (s-2) + (s-2) + (s-2) + (s-2) + (s-2),

= 5 × (s-2),

= 5s - 10,

= 5s - 5×2.

Thus, these are the four expressions for the perimeter of the pentagon.

Solve the simultaneous equation 5x+3y=23 2x+4y=12

uranmaximum [27]

() = Fraction

Answer:

1. x= −(3 /5 y)+ (23 /5)

2. x=−2y+6

Step-by-step explanation:

Let's solve for x.

5x+3y=23

Step 1: Add -3y to both sides.

5x+3y+−3y=23+−3y

5x=−3y+23

Step 2: Divide both sides by 5.

5x /5 = −((3y+23) /5)

x= −(3 /5 y)+ (23 /5)

------------------------------------------------

Let's solve for x.

2x+4y=12

Step 1: Add -4y to both sides.

2x+4y+−4y=12+−4y

2x=−4y+12

Step 2: Divide both sides by 2.

(2x /2 )= −((4y+12) /2)

x=−2y+6

Hope it helped!

Sydney and Mila go to the movie theater and purchase refreshments for their friends. Sydney spends a total of $28.50 on 9 drinks

iogann1982 [59]

The system of equations that can be used to find the price of one drink and the price of one bag of popcorn is:

9x + 2y = 28.50

5x + 10y = 42.50

The price of a bag of popcorn is $3.00

Step-by-step explanation:

Sydney and Mila go to the movie theater and purchase refreshments for their friends

Sydney spends a total of $28.50 on 9 drinks and 2 bags of popcorn
Mila spends a total of $42.50 on 5 drinks and 10 bags of popcorn

We need to write a system of equations that can be used to find the price of one drink and the price of one bag of popcorn and using these equations, to determine and state the price of a bag of popcorn

Assume that the price of each drink is $x and the price of each bag of popcorn is $y

∵ Sydney spends a total of $28.50 on 9 drinks and 2 bags of popcorn

∵ The price of each drink is $x

∵ The price of each bag of popcorn is $y

- Multiply 9 by x and 2 by y, add the products and equate the

sum by 28.50

∴ 9x + 2y = 28.50 ⇒ (1)

∵ Mila spends a total of $42.50 on 5 drinks and 10 bags of popcorn

∵ The price of each drink is $x

∵ The price of each bag of popcorn is $y

- Multiply 5 by x and 10 by y, add the products and equate the

sum by 42.50

∴ 5x + 10y = 42.50 ⇒ (2)

The system of equations that can be used to find the price of one drink and the price of one bag of popcorn is:

9x + 2y = 28.50

5x + 10y = 42.50

Lets solve the system of equations

∵ 9x + 2y = 28.50 ⇒ (1)

∵ 5x + 10y = 42.50 ⇒ (2)

- Multiply equation (1) by -5 to eliminate y

∵ -45x - 10y = -142.50 ⇒ (3)

Add equations (2) and (3)

∴ -40x = -100

- Divide both sides by -40

∴ x = 2.5

Substitute the value of s in equation (1) or (2) to find y

∵ 9(2.5) + 2y = 28.50

∴ 22.5 + 2y = 28.50

- Subtract both sides by 22.5

∴ 2y = 6

- Divide both sides by 2

∴ y = 3

The price of a bag of popcorn is $3.00
