Answer:
x = 1 y = -4
Step-by-step explanation:
- Plug the value of y into the other equation.
x + 3y = -11
x + 3(-4x) = -11
x - 12x = -11
-11x = -11
x = 1
- Now substitute the value of x into any equation.
y = -4x
y = -4(1)
y = -4
Answer:
-2, -1, 0, 1, 2
Step-by-step explanation:
We know, Tanx = sinx / cosx
Tan 90 = sin90 / cos 90
Tan 90 = 1/0
As zero is in the denominator, it can't be defined.
In short, Your Answer would be: "False"
Hope this helps!
