Answer:
Step-by-step explanation:
We have:
To solve, we will isolate the x variable. Therefore, subtract 7 from both sides:
Divide both sides by 2:
Take the square root of both sides. Since we’re taking an event root, we will need plus/minus. Therefore:
Therefore, our solutions are:
Answer:
y = -2x + 3
Step-by-step explanation:
4x + 2y - 6 = 0
2y - 6 = -4x
2y = -4x + 6
y = -2x + 3
Answer:
1 20 20
2 26 26
Step-by-step explanation:
Distribution
12. hope that helps you with your homework
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s
