Answer:
the coordinates of the point of x and y is -1÷ 2 and -√3÷ 2
Step-by-step explanation:
The computation of the coordinates of the point is shown below:
The angle is
= 4π ÷ 3
The radius is 1 unit
Now
x = rcos
, and y = rsin
Now
x = 1cos(4π ÷ 3) = -1÷ 2
y = 1sin(4π ÷ 3) = -√3÷ 2
hence, the corordinates of the point of x and y is -1÷ 2 and -√3÷ 2
Answer:
2
Step-by-step explanation:
these are alternative interior angles so they are equal to each other (congruent) soooo
9x + 4 = 3x + 16
subtract:
9x = 3x + 12
6x = 12
divide
x = 2

Answer:
x=−1, y=−1
Step-by-step explanation:
Solve for x in the first equation.
x=−2−y
10x+3y=−13
Replace all occurrences of x with −2−y in each equation.
−20−7y=−13
x=−2−y
Solve for y in the first equation.
y=−1
x=−2−y
Replace all occurrences of y with −1 in each equation.
x=−1, y=−1
