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
2x - y = 1
2x + y = 7
-------------------add
4x = 8
x = 2
2x - y = 1
2(2) - y = 1
-y = -3
y = 3
answer (1,3)
The equation for perimeter is 2w + 2l. When you substitute this in you get:
2(3m+5) + 2(2m+3)
6m + 10 + 4m +6
10m + 16
Hope this helps
Answer:
The motion of the particle describes an ellipse.
Step-by-step explanation:
The characteristics of the motion of the particle is derived by eliminating in the parametric expressions. Since both expressions are based on trigonometric functions, we proceed to use the following trigonometric identity:
(1)
Where:
(2)
(3)
By (2) and (3) in (1):
(4)
The motion of the particle describes an ellipse.
Zero.
The sum of these angles is 200°. The sum of angles in a triangle must be 180°. These angles cannot be used to form a triangle.
