Answer:
the answer is 0,-180
Step-by-step explanation:
<span>Discriminant is 28 (c)
First get the equation into the form: Ax^2 + Bx + C = 0 (the quadratic equation)..
By subtracting 10x both sides (to get it on the other side)..
9x^2 + 2 = 10x
9x^2 - 10x + 2 = 10x - 10x
9x^2 - 10x + 2 = 0
Now the discriminant is: b^2 - 4ac
The quadratic equation is Ax^2 + Bx + C = 0
Here, A = 9, B = -10 and C = 2
(-10)^2 - 4 (9)(2)
= 100 - 4 (18)
= 100 - 72
= 28</span>
f(x) = x² + 7x + 10
f(0) = (0)² + 7(0) + 10 = 10 ----> (0, 10)
f(2) = (2)² + 7(2) + 10 = 28 -----> (2, 28)

Answer:
a
Step-by-step explanation:
blue red blue red like this
5 meters per second is faster than 720 feet per minute.
5 meters per second is 15 feet per second.
720 feet per minute is 12 feet per second.
You multiply 5 by 3 (3 feet in a meter) to get 15 feet per second.
You divide 720 by 60 (60 seconds in 1 minute) to get 12 feet per second.
15 feet > 12 feet per second.
