Answer:
2x + y = 3
y = -2x + 3 <==
-2y = 14 - 6x
y = -14/2 + 6/2x
y = -7 + 3x
y = 3x - 7 <===
Step-by-step explanation:
Answer:
(x, y) ≈ (-5.89, 1.16)
Step-by-step explanation:
We assume the CD is still accelerating at the same rate at the end of the given time period. The angular position will be found from ...
θ(t) = θ₀ + (1/2)a·t²
Filling in the numbers given, we get
θ(3.51) = (10π/180) + (1/2)(2.49)(3.51²) = 15.51306 . . . radians
The x-y coordinates will be found from ...
(x, y) = radius·(cos(θ), sin(θ)) ≈ 6·(-0.981066, 0.193674)
(x, y) ≈ (-5.89, 1.16)
_____
For the trig functions, the calculator must be in radians mode, unless you have converted the angles to degrees.
Answer: Infinite solutions
Step-by-step explanation: 3x -7 = 3(x-3)+2
3x + -7 = (3)(x) + (3)(-3) + 2
3x + -7 = 3x + -9 + 2
3x - 7 = (3x) + (-7)
3x -7 - 3x = 3x - 7 - 3x
-7 + 7 = -7 + 7
0 = 0
