1+tan^2=sec^2
so, given expression=
(using sin/cos=tan and tan*cot=1)
hence proved
Answer: ∠6, ∠8
Step-by-step explanation:
∠2 ≅ ∠6 because they are corresponding angles of parallel lines cut by a transversal. ∠5 ≅ ∠8 by the Vertical Angles Theorem.
Answer: The domain is all real numbers greater than or equal to
4, and the range is all real numbers
Step-by-step explanation:
Answer:
X - 2.
Step-by-step explanation:
x - 2
----------------------------
x2 – x + 1 ) x3 – 3x2 + 3x – 2
x3 - x2 + x
-------------------
-2x^2 + 2x - 2
-2x^2 + 2x - 2
---------------------
0
Answer:
y = -4
Step-by-step explanation:
How to find the y intercept:
y=2x-4 (Substitute "x" for zero "0")
y=2*0-4 (Solve the equation)
Answer: y = -4
How to find the x intercept:
y=2x-4 (Substitute "y" for zero "0")
0=2x-4 (Move the variable to the left)
-2x=-4 (Divide both sides)
Answer: x = 2
To graph it, go on your coordinate plane and to the x axis. Once you find the point "positive 2" or 2, go down four spaces to "negative 4" or -4. Then just draw your line and you should have your answer!!
I hope this helped!! :]
