The Correct answer is 3
Explanation:
Using the defined function, f(a) will produce the same result when substituted for x:
F(x)=x^2-x^3
Setting this equal to 4, you can solve for a:
a2 – 5 = 4
a2 = 9
a = –3 or 3

Answer: 3:8
Answer:
Step-by-step explanation:
We need to find the solution to the following system of equations:
and 
By plugging the value of 'y' into the first equation we have that:
⇒ 
Solving for 'x' we have:
So, the solution to the system of equation is: (37.5, -30)
Answer:
r=3
Step-by-step explanation:
Simplify the expression
16-2r=3r+1
isolate r by adding 2r to both sides
16=5r+1
isolate the numbers by subtracting 1 from both sides
15=5r
divide both sides by 5 to completely isolate r
r=3
