Answer:
x=<u>-2y+70</u>
5
y=<u>-5x+70 </u>
2
Step-by-step explanation:
Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:
In the given case, you have:
A = 4
T = 3π/4
b = -3
By replacing you obtain:
Hence, the answer is:
f(x) = 4cos(8/3 x) - 3
Answer:
3 outcomes
Step-by-step explanation:
question asks only 1 head therefore THT, TTH, HTT
Answer:
is it 82 degrees?
Step-by-step explanation:
Since both equations equal Y, set them equal to each other and solve.
3x -1 = -2x +9
Add 2x to each side:
5x - 1 = 9
Add 1 to each side:
5x = 10
Divide both sides by 5:
x = 10/5
x = 2
Now replace x with 2 and solve for y:
y = 3(2) -1 = 6-1 = 5
x = 2, y = 5 (2,5)
