Answer:
a
Step-by-step explanation:
given
3(x - 2) < 18 ← distribute the left side
3x - 6 < 18 ( add 6 to both sides )
3x < 24 ( divide both sides by 3 )
x < 8 → a
Answer:
109 yd^2
Step-by-step explanation:
formulas used are
3(1/2 b.h) + 25
...6 and 10 are roots, so x – 6 and x – 10 are factors.
y = a(x – 6)(x – 10).....plug in the point (8, 2) and solve for a:
2 = a(8 – 6)(8 – 10)
2 = –4a
a = –1/2
...y = (–1/2)(x – 6)(x – 10)
...y = (–1/2)(x² – 16x + 60)
...y = (–x²/2) + 8x – 30 <<<------Answer, or:
...y = (–1/2)(x – 8)² + 2 <<<------Answer
Answer:
Step-by-step explanation:
Let us assume that the total area of the wall to be painted is w.
Then Jason painted an area of (1/4)w on Monday
And he painted (2)(1/4)w on Tuesday
So to find the unpainted area, we just take the whole wall area to be painted (which is w) and subtract out the amounts painted on Monday and Tuesday, which are shown above.
So the unpainted area (U) would be shown by the following expression:
U = w - (1/4)w - (2)(1/4)w
We can simplify this expression by factoring out w
U = w(1 - 1/4 - 1/2)
U = w (1/4) or w/4
So all Jason needs to do is paint as much of the wall as he did on Monday, and he will be done!
The answer would be three liters of acid
