Answer: 9-3x
Step-by-step explanation:
You add like terms
don't look at the 3x for now
positive 7 + positive 2 = 9
there is a negative sign next to 3x
9 goes first so
9 - 3x
Answer:
x=9, y=26. (9, 26).
Step-by-step explanation:
x=9
y=3x-1
--------
y=3(9)-1=27-1=26
Answer:
( P -2w) /2 = l
Step-by-step explanation:
P= 2W + 2l
Subtract 2W from each side
P= 2W -2W + 2l
P -2W = 2l
Divide by 2
( P -2w) /2 = l
The equation for height as a function of time is:
height = (0.5)(acceleration)(time)^2 + (initial velocity)(time) + (initial height)
In this case, x will be the time, so 80 fits the initial height from which the parachute is dropped (the first choice).
The initial velocity of the parachute is 16, while acceleration is -32 (units of length are probably in ft).
Answer:
No solution.
Step-by-step explanation:
8x - 4 = 2(4x - 4)
8x - 4 = 8x - 8
-4 = -8
-4 ≠ -8
