What is the coefficient of the fourth term in the expansion of (x - y)^6?

Zarrin [17]

<span>If you're aware of the binomial theorem, you have that:
</span> $(x-y)^6=\sum_{k=0}^{6}\binom{6}{6-k}x^k(-1)^{6-k}y^{6-k}$
$(x-y)^6=\sum_{k=0}^{6}\binom{6}{k}x^k(-1)^{k}y^{6-k}$

The fourth term is then the case $k=3$ , from which:
$c_{3}=\binom{6}{3}x^3(-1)^3y^3= \frac{6!}{3!(6-3)!} * (-x^3y^3)=- \frac{720}{36}x^3y^3=-20x^3y^3$

BRAINLEST ANSWER!! please show the steps<br><br> 4 (2x-7) +4 > -88

Ronch [10]

Answer: x>−8

Step-by-step explanation:

Let's solve your inequality step-by-step.

4(2x−7)+4>−88

Step 1: Simplify both sides of the inequality.

8x−24>−88

Step 2: Add 24 to both sides.

8x−24+24>−88+24

8x>−64

Step 3: Divide both sides by 8.

8x/8 > -64/8

x>−8
