Answer:
see explanation
Step-by-step explanation:
Use the points to find a and b, that is
(2, 18)
18 = a → (1)
(4, 162)
162 = a → (2)
divide (2) by (1)
= = 9
b² = 9 ⇒ b = 3
substitute b = 3 into (1)
18 = 9a ⇒ a = 2
y = 2 ← exponential equation
Answer:
161.5 miles
Step-by-step explanation:
19 inches is 9.5 times 2 inches. So, the actual distance is 9.5 times 17 miles:
9.5 × 17 miles = 161.5 miles
Answer:
keep 4/9 as it is.
multiply 2/3 by 3/3 and you get 6/9.
add 4/9 and 6/9.
you get 1 and 1/9 as your answer.
There were no slopes listed below but in order for two equations to be parallel they need to have the same slope. So in this case any equation with a slope of 5x would be parallel to your equation.
