Let x be that number
2x -3 = x-6 solve for x ; x=-3
Answer:
A
Step-by-step explanation:
In that example the plane is going up constantly whereas in example B the plane in going down, in example C the plane it going up but the stops and goes at the same speed, and in D the plane it once again going down.
Answer:
Infinite many solutions - all are correct
Step-by-step explanation:
Since f(x) and g(x) are the same function, their graphs will be the same and all points on the line are solutions. All x values will be solutions. This means there are infinitely many.
You can see it algebraically too:
-2x-6 = -2x-6
-2x+2x-6 = -2x +2x -6
0-6 = 0-6
-6=-6 True. Infinite solutions.
A*b*sin(c) / 2
8*21*sin(68)=77.88 or rounded 77.9
Solve the given equation:
13 + x = 29
Subtract 13 from both sides:
x = 16
Now look at each choice and solve for x.
A. 29 + 13 = x
x = 42
B. 13 = 29 - x
-16 = -x
x = 16
C. x = 29 - 13
x = 16
D. 13 - x = 29
-x = 16
x = -16
Choices B and C have the same solution as the given equation, so choices B and C are equivalent to the given equation.
