Roots can be written as fraction exponents. An exponent of 1/2 means the square root.
1 cm = 20 km
so 3.5 cm would equal : 3.5 * 20 = 70 km <==

Passes through k(3,-3)
Equation in point slope form
- y-y1=m(x-x1)
- y+3=-5(x-3)
- y+3=-5x+15
- y=-5x+12
Check one by one
- 0=-5(-12)+12=60+12=72
- 2=-5(2)+12=-10+12=2
Yes option B is correct
Answer:

Step-by-step explanation:

Let the number of adults be n. Each adult ticket costs $9, so the cost of n adult tickets is 9n. There is only one child, and a child's ticket is $6, so the cost of the child's ticket is 6. Adding the costs, you get 9n + 6. The total cost is $78, but the expression representing the total cost is 9n + 6, so 9n + 6 must equal 78. That is the equation.
9n + 6 = 78
