Lets write an equation for this :)
So, the sum of -3 times a number and 0.3
This would be : -3x +0.3
Is at most, 6.3
so, it is equal to, or less than 6.3
-3x +0.3 <u><</u> 6.3
Now lets solve!
x<u>> </u>-2
the number is greater than or equal to -2
Answer:
See below.
Step-by-step explanation:
Values are excluded if they make the denominator zero, so one rational expression could be:
(x^2 - 9) / (x + 4)(x + 7)
- when x = -4 or -7 then the denominator is zero so the values of the function is undefined for these values.
