Let these two numbers be 
and 
. Their sum is 
, their difference is -4, and their product is -29:
Add the first two equations together to eliminate :
Then
Just to confirm this is correct, check their product:
Answer:
The answer is two seconds
Step-by-step explanation:
Set the y to 0 as we are looking for the height when f(t) has hit the ground. Then factor and the two zeros of the function are -2 and 2. because the -2 is an answer that that cannot make sense for time in a real world scenario, the answer is the positive zero, or two. :-)
Answer:
g+12/4
Step-by-step explanation:
Let x=large boxes and y=small boxes.
x+y=110
60x+35y=5100
____________
You need to cancel out one of the variables to solve for one. Let's cancel out y.
-35(x+y=110)
-35x-35y=-3850
60x+35y=5100
____________
Add the two equations.
25x=1250
x=50
_____________
Plug in 50 for x into one of the equations to solve for y.
50+y=110
y=60
_____________
50 large boxes
60 small boxes
Picture is to blurry fix the pic and I will answer it if I can
