Mr. Fredrick burns about 2100 calories per day without exercising. For each mile that he walks, he burns an additional 150 calories. Write a linear function modeling the number of calories Mr. Fredrick burns in a given day. How many miles should Mr. Fredrick walk each day to maintain his current weight if he eats 2700 calories per day?

Y=150x+2100

Step-by-step explanation:

He will have to walk 4 miles to maintain his weight

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

the answer is 8.64
