F(x) = -5 x + 10
Then
f(-2) = -5(-2) + 10
= 10 + 10
= 20
Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.
The question is asking to choose among the following choices that states the expressions that could be represented in the said phrase and in my further understanding, I would say that the answer would be n.7, I hope you are satisfied with my answer and feel free to ask for more
#9 is yes because 12 is double 6. 6+6=12 I don't know #10. Sorry!
