Luke is keeping track of the total number of hours he exercises. He started the summer having already put in 15 hours, and he then exercises 7 hours each week. The function to keep track of his exercise is f(x) = 7x + 15. What do the f(x) and x represent in Luke's situation? (2 points)A) f(x) represents the total number of hours; x represents the number of weeks he exercises this summer
B) f(x) represents the total number of weeks that he has exercised; x represents the number of hours
C) f(x) represents the number of hours he exercises per day; x represents the number of weeks
D) f(x) represents the total number of hours that Luke has exercised; x represents the number of weeks he exercises per day

Answers

Answer 1

Answer: If you would like to know what do the f(x) and x represent in Luke's situation, you can find this using the following step:

f(x) = 7x + 15
7 hours each week
x ... the number of weeks
f(x) ... the total number of hours Luke exercises

The correct result would be A) f(x) represents the total number of hours; x represents the number of weeks he exercises this summer.

Answer 2

Answer:

f(x) represents the total number of hours; x represents the number of weeks he exercises this summer.

What is the area in square units of a triangle on an XY plane with vertices (2,3) , (9,3) and (5,6)

Answers

To find the area of a triangle with vertices (2,3), (9,3), and (5,6) on the XY plane, you can use the formula for the area of a triangle:

Area = 1/2 * |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|

Using the coordinates:

x1 = 2, y1 = 3
x2 = 9, y2 = 3
x3 = 5, y3 = 6

Area = 1/2 * |2(3 - 6) + 9(6 - 3) + 5(3 - 3)|

Area = 1/2 * |-6 + 27 + 0|

Area = 1/2 * 21

Area = 10.5 square units

So, the area of the triangle is 10.5 square units.

Three times the sum of a number and seven is two less than five times the number.

Answers

3 (x + 7) = 5x - 2
3x + 21 = 5x - 2
3x - 5x = -2 - 21

-2x = -23
x = -23/-2
x = 23/2

The Greens want to put an addition on their house 18 months from now. They will need to save $10,620 in order to achieve this goal. They set aside the same amount each month, and after a year discover they have saved $6,120. The Greens must adjust their plan in order to meet their goal, so they came up with the following options: Option A: Stay with saving the original amount each month but put the addition on one month later than originally planned. Option B: Increase the amount of money they save each month by $120 from their original plan.
