First, you set your problem up like this:
-4x+3=2x-6
add 6 to both sides so it looks like this:
-4x+9=2x
add 4x to both sides so it looks like this:
9=6x
divide 6 from both sides so this is your answer:
1.5=x
I don’t think it’s the second or third one I’m narrowing it down to the first or maybe fourth
I think the answer is the first one though
Answer:
cos l = 8/10
Step-by-step explanation:
cos = b/h
=> cos l = 8/10
When stone hits the ground, it's height will be zero, and since we're finding the time that's required for the stone to hit the ground, we can set h = 0 and solve for t.
I know its a long problem but i have to shiw how i got my answer.
