Answer:
um OK
Step-by-step explanation:
f
Every triangles 3 angles will always add up to 180 degrees
The reason this is true in your problem is because of the corresponding angles and supplementary angles.
Hope this helps
4 - 4y - y² = 0
-y² - 4y + 4 = 0
y = -(-4) ± √((-4)² - 4(4)(-1))
2(-1)
y = 4 ± √(16 + 16)
-2
y = 4 ± √(32)
-2
y = 4 ± 4√(2)
-2
y = 4 + 4√(2) or y = 4 - 4√(2)
-2 -2
y = -2 - 2√(2) or y = -2 + 2√(2)
The answer is C.
Let y= mx-2 be the tangent line to y=x^2-4x+2 at x=a.
Then slope, 
Hence the equation is y=(2a-4)x-2
Let's find y-coordinate at x=a using tangent line and curve.
Using tangent line y at x=a is (2a-4) a -2 
Using given curve y-coordinate at x=a is 
Let's equate these 2 y-coordinates,



a=2 or -2.
If a=2, 
If a=-2,
Hence m values are 0 and -8.
if the first number is x and the second number is y
1^3 = 1
2^3 =8
3^3=27
4^3 = 64
y=x^3
f(x)=x^3
