Answer:
(0,6), and (18,0)
Step-by-step explanation:
2x +6y = 36
6y = -2x +36
y =(-2/6) x+ 36/6
y=(-1/3)x +6
compare this equation to y=mx+b where b is the y-intercept so the
y-intercept is a point at (0, 6)
to find the x-intercept make the equation equal to 0
(-1/3)x+6=0 subtract 6 in both sides
(-1/3)x = -6 cross multiply
-x = 3*-6
x=18 so the
x-intercept is a point at (18,0)
The rate of increase is found by differentiating with resepect to time. The product rule comes into play here.
A = LW
dA/dt ≈ (dL/dt)·W + L·(dW/dt)
... = (6 cm/s)·(5 cm) + (7 cm)·(3 cm/s)
... = 30 cm²/s + 21 cm²/s
... = 51 cm²/s . . . . rate of area increase
Answer:
3x + 7 + 5
Step-by-step explanation:
I could be wrong... there are 3 x's so that would be 3x, and then the 7 and 5. sorry if i'm wrong
It's 340. You multiply 400 by .85 to get your answer.
I think she made a mistake at step 4 because I know in order to find the mean absolute deviation of a number you must divide as the last step, not subtract and the rest of her work looks correct.
