Answer:
XW = 4 units
Step-by-step explanation:
Given tanf° =
, then
tanf° =
=
=
=
( cross- multiply )
2XW = 8 ( divide both sides by 2 )
XW = 4
Answer:
The last choice.
Step-by-step explanation:

The value of k must be restricted from being one that makes the original denominator zero. Hence k ≠ -1 or 5.
The wording of your question suggests that there were answer choices. Mind sharing them?
The system <span>y=-2x^2 y=x-2 would be best written as:
</span><span>y=-2x^2
y=x-2 If you subst. x-2 for y in the first equation, you'll get:
x-2 = -2x^2, or 2x^2 + x - 2 = 0.
