Answer:
a.) 70 km per hour
b.) 245 km
Step-by-step explanation:
a.) Find how far the car can travel per hour by dividing:
The car travels at a rate of 70 km per hour.
b.) Make an equation with <em>h</em> as hours and <em>d</em> as the distance the car can travel:
Insert the hours:
Simplify:
At a rate of 70 km per hour, in 3.5 hours, the car can travel a total of 245 km.
Answer:
4n -13
Step-by-step explanation:
notice that the difference between the adjacent terms is 4.
nth term is given by:
nth term = first term + (n-1) × difference -n is any number
= -9 + (n-1) × 4
= -9 + 4n -4
= 4n -13
Answer: h=2.7
Step-by-step explanation:
Answer: 25 dollars per game
Step-by-step explanation:
Answer:
both choices with 2x+y = -3
Step-by-step explanation:
to have the solution (-4, 5), that point must be on both equations/functions, meaning it must be on either one.
in other words, if the point is not on at least one of the functions, it cannot be a solution for that system.
the given function
2x + y = -3
looks like for the point (-4, 5)
2×-4 + 5 = -3
-8 + 5 = -3
-3 = -3
correct.
but
-2x + y = -3
looks like for (-4, 5)
-2×-4 + 5 = -3
8 + 5 = -3
13 = -3
wrong. the point is not on this function.
as we can therefore rule out 2 of the answer options, the other 2 most be correct.
