Answer:
1. {5,-9}
2.{4}
3.{9/2}
Step-by-step explanation:
The equation 
can be solved as follows:
Then, the solutions of the equation are 
.
Now, if 
, we can solve the equation 
as follows:
So, the unique solution of this last equation is 
The last equation is 
, where 
. To solve this equation we can proceed as follows:
But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.
Sin ( theta ) = opposite / hypotenuse
sin ( 37° ) = 13 / x
Answer:
B. 13
Step-by-step explanation:
g(x)=4x+1
g(3)=4(3)+1
g(3)= 12+1
g(3)=13
Answer:
12 and 93.
Step-by-step explanation:
Let the grandsons age be x then Mr. Roger's age = 8x - 3.
Five years ago the grandson's age was x-5 and Mr Rogers was 8x - 8 years old , so:
8x - 8 - (x - 5) = 81
8x - 8 - x + 5 = 81
7x = 81 + 8 - 5 = 84
x = 12.
So the grandson is 12 and Mt Rogers is 8*12 - 3 = 93.
