You put 15 gallons of gasoline in your car. you know that this amount of gasoline will allow you to drive about 450 miles. write and graph an equation to represent each situations.

The required equation is y=30x.

Step-by-step explanation:

It is given that we can drive 450 miles in 15 gallons of gasoline.

The number of miles covered by a car in 1 gallons of gasoline is

It means a can cover 30 miles in 1 gallons of gasoline.

Let x be the number of gallons of gasoline and y is distance. So, the required equation is

where, 0 ≤ x ≤ 15 and 0 ≤ y ≤ 450.

The table of values is

 x             y

 0            0

 5           150

 10         300

 15         450

The graph of above equation is shown below.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
