1. (4,1) is not a solution because when u sub it into the equation, it does not come out correct. It would be correct if it was (1,4).

2. C = 2.50d.....where C is the cost and d is the number of drinks bought. And if u pick any number for d, then u can solve for the cost (C).

Answer:

1. The point (4,1) is not a solution for the equation.

2. y=2.50x

Step-by-step explanation:

1. We are asked to explain why (4,1) is not a solution to the equation y=3x+1.

We can see that right side of equation would be greater than left side, when we will substitute coordinates of point (4,1).

Let us substitute coordinates of point (4,1) in our given equation as:

1=3(4)+1

1=12+1

1=13

Therefore, the point (4,1) is not a solution for the equation.

2. We have been given that drinks at the fair cost $2.50.

Let x represent number of drinks, so cost of x drinks would be 2.50x.

The total cost (y) of x drinks would be y=2.50x.

Therefore, the equation 2.50x represents the given equation.

Table:

Number of drinks                       Total cost

1                                                       $2.50

2                                                      $5.00

3                                                       $7.50

4                                                      $10.00

a rain gutter is 24 feet long, 4 inches in height, 3 inches at base and 6 inches at top. how many gallons of water will it hold?
Lubov Fominskaja [6]

Answer:1.8701

Step-by-step explanation:

Area (A) of trapezium as marked is =\frac{1}{2}\left ( sum\ of\ parallel\ sides\right )\times height

A=\frac{1}{2}\left ( 3+6\right )\times 4

A=18in^2

Now for Volume we have to multiply by length because area is same across the length.

volume(v)=A\times length

Volume(v)=18\times 24

Volume(v)=432 in^3

Volume(v)=1.8701 gallon
