2x+y=8 is the equation perpendicular to x-2y=8.
Answer:
3
Step-by-step explanation:
Remember the order of operations using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). So, you get 18 - 6 / 5-1 = 12/4 = 3
Answer:
0.125 or 1/8
Step-by-step explanation:
2^3 +2^-3= (2*2*2) + (1/(2*2*2))= 8 + 1/8= 8 + 0.125= 8.125
4^3 +1= (4*4*4) + 1= 64 + 1= 65
8.125/65= 0.125 or 1/8
