Give work for equations following: -x+2y<-4 2x+3y>6 thanks sooooo much!!!!

Schach [20]

Answer: See below

Step-by-step explanation:

A) $-x+2y < -4$

$-x+2y-2y < -4-2y$

$-x < -4-2y$

Multiply both sides by -1 and reverse the inequality:

$\left(-x\right)\left(-1\right) > -4\left(-1\right)-2y\left(-1\right)$

$x > 4+2y$

B) $2x+3y > 6$

$2x+3y-3y > 6-3y$

$2x > 6-3y$

$\frac{2x}{2} > \frac{6}{2}-\frac{3y}{2}$

$x > \frac{6-3y}{2}\\x > 3-\frac{3y}{2}$

1) Cancel out the common factor which in this case is 8 $\frac{16m^2}{24m^7} = \frac{2m^2}{3m^7}$

2)First apply exponent rule $\frac{n(n+7)}{4n(n+7)}\\$ now cancel out the common factors which are n and n+7 leaving you with $\frac{1}{4}=0.25$

3)Factorize $\frac{(x+2)(x-12)}{x+2}$ cancel out the common factor in this case x+2 leaving you with $x-12$

4) Factorize $\frac{(-3w+1)(3w-1)}{4(3w-1)}$ cancel out the common factor in this case 3w-1 leaving you with $\frac{-3w+1}{4}$

5) In the picture

I am REALLY tired sorry I wont be able to do the rest, I hope these are helpful :)
