For the number before x you would look for the rise over the run. in this case you can see that there is an intersection at (-2,0) and (0,1) you find the difference ox each so you have 2/1 or just 2 you can tell that the line is going up so it is positive. for the addition part look at where the y intercept is in this case it is at positive one. this makes your equation y=2x+1

Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet
hichkok12 [17]

Answer:

Set up your height equation, then factor or use quadratic formula to find when h(t)=0

Step-by-step explanation:

Your equation will be -16t^2+vt +h where v is the initial velocity and h is the starting height. Now either factor or quadratic equation, whichever is easier for you.

Remember that the ball is on the ground when h(t)=0 since that is the height. There will be two zeros,  one is a negative number so would be before you kicked the ball, the other one will be when the ball comes back down.

What mixed number is equivalent to 12/10
kvasek [131]

Answer:

1 1/5

Step-by-step explanation:

To get the answer you pratically change 12/10 into a mixed number.

So you say 12 divided by 10 which is 1 leaving a remainder of 2

We write it like this:

1 2/10

We can then reduce it to its simpliest form and it becomes 1 1/5

HOPE IT HELPED
