Answer:
x=8/3
y= -20/9
Step-by-step explanation:
4X + 3Y -4 =0
Linear egquations must in
so 4X + 3Y =4
THEN
3X + 9Y = - 12
next use calculator to solve it or you can use traditional way
We need a better picture, we can't even tell which is #7
G(-1) = 1 / -1 = -1
f(g(-1)) = (-1)^2 + 9(-1) = 1 - 9 = -8 Answer
f(1/2) = (1/2)^2 + 9(1/2) = 1/4 + 4 1/2 = 19/4
g((f(1//2)) = 1 / 19/4 = 4/19 Answer
Find coterminal angles Ac to a given angle A.
What are coterminal angles?
If you graph angles x = 30o and y = - 330o in standard position, these angles will have the same terminal side. See figure below.
<span><span><span> </span> </span> </span>
Coterminal angles Ac to angle A may be obtained by adding or subtracting k*360 degrees or k* (2 Pi). Hence
Ac = A + k*360o if A is given in degrees.
or
Ac = A + k*(2 PI) if A is given in radians.
where k is any negative or positive integer.
