Answer:
The first one
Step-by-step explanation:
Negative 5 is smaller than negative 3. 0.8 is smaller than one. 1 is smaller than 1.5
3x-5>-4x9
3x+4x>9+5
7x>14
x>2
Hey there! :)
Answer:
f(15) = 29 ft.
Step-by-step explanation:
We can write an arithmatic equation for this pattern:
Where:
= 1, = 3
Find the rate of change. This is constant because this is an arithmatic sequence.
3 - 1 = 2.
We can begin to write an explicit function for this situation:
f(n) = + d(n-1) where d is the rate of change:
f(n) = 1 + 2(n-1)
Substitute 15 for n to solve for the distance traveled after 15 seconds:
f(15) = 1 + 2(15-1)
f(15) = 1 + 2(14)
f(15) = 1 + 28
f(15) = 29 ft.
Therefore, the distance traveled after 15 seconds is 29 ft.
Answer:
C. 50
Step-by-step explanation:
x+y=90
x=2y-30
90-y=2y-30
3y=120
y=40
90-40= 50
