Answer:
d has is the graph with the slope of 1/2.
Step-by-step explanation:
the rise over run from point to point is how you determine the slope.
i hope this helps :)
Answer:
( x - 3i ) ( x + 3i )
= x^2 + 3xi - 3xi - 9i^2
= x^2 - 9 (-1)
= x^2 + 9
(x^2 + 9 ) ( x + 5 )
Now the left hand side is equal to the right hand side.
Good luck!

Answer:
50.18°
Step-by-step explanation:
∠BAD = ∠BAC +∠CAD
102° = (8x+17)° +(9x+11)° . . . . . substitute given values
102 = 17x +28 . . . . . . . . . . simplify, divide by degrees
x = (102 -28)/17 = 74/17 . . . . . solve for x
Then the angle of interest is ...
∠CAD = (9x +11)° = (9(74/17) +11)° = 50 3/17°
∠CAD ≈ 50.18°
Answer:
The value of a = - 1 , And b =
Step-by-step explanation:
Given as :
Function f(x) =
And f(f(1)) = 0 And f(2) = - 3
Now For , x = 2 , y = - 3
I.e f(2) =
or, - 3 =
I.e 2 + a = - 6 - 3b
Or, a + 3b = - 8 ....... 1
Again f(f(1)) = 0
So, = 0
Or, 1 + a = 0
∴ a = - 1
So , put htis value of a i n eq 1 , we get value of b
So , - 1 + 3b = - 8
Or, 3b = - 7
∴ b =
Hence The value of a = - 1 , And b = Answer
