Answer: -17/28
Step-by-step explanation:
This is very easy.
We read f(x) as "a function of x"
Think of it as a machine. It takes in x, and gives us f(x) after doing some things to it.
f(x) = (x) × 4/7 + 9/4 ,
f(-5) = (-5) × 4/7 + 9/4
Let's work this out now!
= (-5) × 4/7 + 9/4
= -20/7 + 9/4
Now make into 1 fraction with common denominator
= -80/28 + 63/28
= -17/28
4 + 2 [ 10(6 * 2 - 6) - 40 ]
4 + 2 [ 10(12 - 6) - 40 ]
4 + 2 [ 10(6) - 40 ]
4 + 2 [ 60 - 40 ]
4 + 2 [ 20 ]
4 + 40
44 <===
1. Factor out the x^1/3.
X^1/3(x^1/3 +2)=0
That means either x^1/3 equals 0 or x^1/3+2 equals 0.
For x^1/3=0, x=0
For x^1/3+2=0
X^1/3=-2
X equals -8
Therefore, x can be 0 or -8
