x = 7
3*x-6-(15)=0
3x - 21 = 3 • (x - 7)
Solve : 3 = 0
Solve : x-7 = 0
Add 7 to both sides of the equation :
x = 7
Answer:

Step-by-step explanation:
Given
Point: A(2,6)
Translation: 1 left and 3 up
Rotation: 180 degrees
Required
Image of Point A
Taking the exercise one after the other
<em>Represent the function as: (x,y)</em>
Such that

1 unit left translation means the function becomes (x - 1, y)
2 unit up translation means the function becomes (x - 1, y + 2)
Applying the above transformation


At this stage, the coordinate becomes

When a function (x,y) is rotated by 180, the new function becomes (-x,-y)
So;
The further transformation of A is

Hence, the new image of A is

0.87= 87/100
But there is no choice even though it is the right answer
Answer is 87/100
Let k and d be the Kevin's age and the Daniel's age;
We have the equation:
k = 3 + d;
k - 2 = 4( d - 2 );
We have 3 + d - 2 = 4d - 8;
Then, d + 1 = 4d - 8;
9 = 3d;
d = 3.
Finally, k = 6 years.
Answer:
x = -4
