No triangles can be constructed because
a+b>c
4+5 is not greater than 9
Let K = km in 7 weeks
Equation:
K = 7(20)
Substituting the given information into the formula gives
0 = 48t - 16t²
Factoring, this becomes
0 = 16t(3-t)
The ball is at ground level when t=0 or t=3.
The ball hits the ground after 3 seconds.
There are fewer people on the bus.
The start of it had at least 5
The end of it had at least 1
Answer:
x<3
where x does not exist
(-infinity, 3)
Where x exists
[3, infinity]
Step-by-step explanation:
I'm just going to answer the first one.
Treat it like your solving for x, however the only difference is that it's an inequality.
3x-2 <7
3x< 7+2
3x/3x < 9/3
x<3
Now we know where x does and does not exist.
I'm assuming your teacher wants that, (-infinity, 3) (this is where it does not exist)
[3, infinity]
In case you were wondering square brackets is where it exists and curled is where it doesn't.
