Answer:

A.) 65x + 35X + 50 = 250

65x = cost of concrete per cubic yard, x is yd³

35X = cost of pouring/finishing concrete per cubic yard, X is yd³

50 = delivery cost

250 = the money you have

B.) 400 + 15n = 505

15n = amount of money you deposite per week, n is # of week

400 = some money in account after n week passed

505 = initial money in bank

C.) 1.1X - 10 = 55

55 = total cost of clothes

1.1X = tax rate where X is the undiscounted clothe cost

10 = discount

Korvikt [17]

The correct answer is a.

Inside the function it says x+2, and a +2 means it is to the left (direction is opposite of the sign)

The 3 on the outside of the function shows how the steepness, or slope will change. The first is correct because slope is rise over run, and if you go from one point to another, you'll see that it is up 3 and over 1, or 3/1, or 3.
