Nathan is using his grandmother's recipe to make pies. On Monday, he used 15 cups of sugar to make 9 pies.
On Tuesday, he used 22 cups of sugar to make 13 pies.
Which of the following statements must be true?
Select all that apply
A
He used 1 cup of sugar for every 15 pies he made.
B
He would use 11 cups of sugar to make s ples
С
The number of cups of sugar is proportional to the number of pies he made because he used the same number of cups of sugar for each pie he made
D
The number of cups of sugar is not proportional to the number of pies he made because the increase in the number of cups of sugar between Monday and Tuesday is greater than the
increase in the number of pies
E
If Nathan uses 8 cups of sugar to make 5 pies on Wednesday and then graphs the points, for all three days, to represent the relationship between the cups of sugar used and the
number of ples made the points would not fall on a straight line

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
