6x^+4(x^-1) simply this question
1 answer:
1. when you see 4(x² - 1), then you have to multiply 4 with everything in the bracket. keep in mind that you always have to be cautious of the sign whether it is a positive or a negative.
positive ×/÷ positive = positive
negative ×/÷ negative = positive
positive ×/÷ negative = negative
negative ×/÷ positive = negative
^ you have to remember this.
2. only like terms (same alphabet) can plus or minus each other.
3. simplify by taking out the common factor and placing it outside the bracket. though, keep in mind that you also have to divide the terms inside the bracket by the common factor.

Answer:
C
Step-by-step explanation:
Check all points:
A: x=0, y=10, then from the equality follows that A lies on the line.
B: x=3, y=13, then from the equality follows that B lies on the line.
C: x=8, y=2, then from the inequality follows that C doesn't lie on the line.
D: x=5, y=15, then from the equality follows that D lies on the line.
