Answer:
x = -2
y = 3
Step-by-step explanation:
-5x + 3y = 19
x = 3y - 11
-5x + 3y = 19
-5(3y - 11) + 3y = 19
-15y + 55 + 3y = 19
-15y + 3y + 55 = 19
-12y + 55 = 19
-12y = 19 - 55
-12y = -36
y = -36/-12
<u>y = 3</u>
x = 3y - 11
x = 3(3) - 11
x = 9 - 11
<u>x = -2</u>
Answer:
(−∞,+∞)
Step-by-step explanation:
The cotangent function can take up any values depending on the value of
x
, the independent variable.
And thus, the range
(
−
∞
,
+
∞
)
is justified.
The domain is all real numbers other than integral multiples of
π
where, the function is not defined.
