Question

I am stuck on this assignment

Answer 1

Answer:

1. -8/11

2. -1 3/7

Step-by-step explanation(Q1):

Using order of operations, start with parentheses and work with exponents second. Then, M/D/A/S.

$5-3\\=2\\=2^{3}\\=\boxed{8}\\3^2\\=9\\=1+9-21\\1+9\\=10\\=10-21\\=\boxed{-11}\\=\frac{8}{-11}$

Step-by-step explanation(Q2):

Given x = 3, y = -2

$4\left(3\right)\\=12\\=12+\left(-2\right)\\12+\left(-2\right)\\=12-2\\=10\\\downarrow\\2\left(-2\right)\\=-4\\=-4-3\\=\left(-4\right)-3\\=-7\\=\frac{10}{-7}\\=-\frac{10}{7}\\\\\bold{Long~Division}\\7 \div 10 = 1\\1 \times 7 = 7\\7 - 10 = 3\\= 1,R3\\\\\frac{10}{7}\\=1\frac{3}{7}\\=-1\frac{3}{7}$
