Y= 40 explanation don’t want to just trust me it’s 40
Answer: Equation: 4
-2
; estimate: a
little more than 2 inches; answer: 2 
inches.
Step-by-step explanation:
Take the GCF (-8t) of the given expression.
You'll get -8t(2t-5).
Now, set each equal to zero and solve for x.
-8t = 0 2t-5=0
t=0 t = 5/2 (Or 2.5 seconds)
Yes,
y=x+3
if x=0,
y=0+3
y=3
therefore (0,3) is a solution
