Answer:
Answer is a = -4
3a + 4 = 2a
Subtract 2a from each side
a + 4 = 0
Subtract 4 from each side
a = -4
Step-by-step explanation:
Answer:
4 seconds.
Step-by-step explanation:
The given equation is
where, h is height in feet of a golf ball above the ground after being hit into the air and t is the number of seconds elapsed since the ball was hit.
We need to find the time for the ball to hit the ground.
At ground level the height of ball is 0, i.e., h=0.
Using zero product property, we get
Therefore, it will take 4 seconds for the ball to hit the ground.
Answer:
The temperature at 10 pm was -1 degrees and the arrows helped you understand when the temperature increased and decreased.
Step-by-step explanation:
At 8 am, we know that the temperature is -3 degrees, or 3 degrees below zero. By 1 pm, the temperature has risen by 14 degrees and is now 11 degrees. We know this because -3+14=11. Now by 10 pm, the temperature has dropped 12 degrees which means that it's -1 degrees. (11-12=-1) The plot points would be all of the temperatures, or -3, 11, and -1. The arrows you need to draw are from -3 to 11 (an increase) and from 11 to -1 (a decrease). Drawing the arrows this way represents the temperature at different times and how it changed over time.
