Answer:
B
Step-by-step explanation:
I've taken a picture of the way I solved it.
S(x) = x^3
Make x the subject:-
x = (S(x))^ 1/3 = ∛ S(x)
Inverse is ∛ S(x)
Answer:
The desired equation is y = x + 8.
Step-by-step explanation:
As we move right from (-2,6) to (4,12), x increases by 6 and y also increases by 6. Thus, the slope, m, m = rise / run, is m = 6/6, or just m = 1.
Start with the slope intercept form y = mx + b. Since m = 1, we now have y = x + b. Subbing 4 for x, 12 for y, we can find b: 12 = 4 + b. Thus, b = 8.
The desired equation is y = x + 8.
Multiply by two
2/5 x 2/1 = 4/5
X = length of third side
The third side is unknown and can't be determined to be one fixed number. However, we can find a set of values or a range of acceptable values
If we know that
a = 6
b = 7
are the two given sides, then we can say
b-a < x < b+a
7-6 < x < 7+6
1 < x < 13
So the third side x can be between 1 and 13.
The third side cannot be equal to 1 unit or 13 units because a triangle would not form. Instead a straight line would form.
Note: This idea is using the triangle inequality theorem
