Set up an equation for both Sarah and Joe.
Sarah's equation would be 59+19.50x=y
Joe's Equation would be 149+9.50x=y
The goal is to get y to equal the lowest number. If we plug in 1 for x for both equations we get:
59+19.50(1)=y for sarah and Joes would be 149+9.50(1)=y.
Sarah would pay $78.50 for her 1st month and Joe would pay $158.5 for his 1st month. Sarah pays much less than joe but over a few months Sarah would pay more eventually. Hope I helped and if you have any questions, just leave a comment.
Hello,
Addition : no because -1+(-1)=-2 not in set.
Division : no because 1/0 is not in the set :infinity
Multiplication yes: {-1,0,1}*{-1,0,1}={-1,0,1}
Substraction: No because (-1)-(1)=-2 not in set.
Answer C
(6x^-2)^2(0.5x)^4 = (6^2)(x^-2(2))(1/2)^4(x^4) = 36x^-4(1/16x^4) = (36/16)x^(-4+4) = 9/4
Answer:
Negative

Answer:
Step-by-step explanation:
You are supposed to pull out the common factor and put it outside the brackets.
42: 6 * 7
54: 6 * 9
So the answer is
6(9 + 7)
