X-12 -8
calculate the difference
X-20
Answer:
5
Step-by-step explanation:
You must have x alone
Answer:
x=-4
Step-by-step explanation:
Dividing both sides by -3, you get x+2=-2. So x=-4.
Step-by-step explanation:
<u>1</u><u> </u> x-y = 10
2
multiply by 2
2* (<u>1</u> x+y) =10
2
x+y=20
Calculating x=3 and x=5, we get f(x)=10 and 4 respectively by plugging the numbers into the equation. Finding the difference and dividing by 2 (since there are 2 seconds between 3 and 5), we get 3, so the answer is either A or C. Since it doesn't only fall 3 feet, we need to specify that it is 3 feet per second, A is right!
