Answer:
-4 < x < 2
Step-by-step explanation:
- -4 is where the first point begins.
-4
- since the point is "open", aka not shaded, it should be "<"
-4 <
- we now have to insert the given variable, x
-4 < x
- the second, ending point, is also "open"
-4 < x <
- the ending point lands on 2
-4 < x < 2
hopefully this answers your question. but a little fyi, this is simply the way i learned it, so it may/may not be what you exactly need :)
The slope is the same as rate of change. In a linear graph, it is the change in y over the change in x.
Answer:
b) -2/5
Step-by-step explanation:
b is -2/5 because its negative and goes down at a rate of 0.4 or 2/5
a , ummmm IDK that, sorry
Brainliest, crown to me
Answer:
h(t) = -16t2 + 144
h(1) = -16(12) + 144 = 128 ft
h(2) = -16(22) + 144 = 80 ft
h(2) - h(1) = 80 - 128 = -48 ft
It fell 48 ft between t = 1 and t = 2 seconds.
It reaches the ground when h(t) = 0
0 = -16t2 + 144
t = √(144/16) s = 3s
It reaches the ground 3s after being dropped.
Step-by-step explanation:
157 degrees ... set 4x-5 = x+16 then solve, you should get x=7, plug in 7 for one of the equations and you'll get 23. subtract 23 from 180 and get 157. hope that helped :)
