Answer:
7/10
Step-by-step explanation:
Lets set up this word problem as an equation to make it easier to solve.
1/2+2/5 - 1/2 x 2/5
<em>Now lets solve using PEMDAS:</em>
<em />
1/2+2/5 - 1/2 x 2/5 1/2 x 2/5 = 1/5
1/2 + 2/5 - 1/5 1/2 + 2/5 = 9/10
9/10 - 1/5 = 7/10
Answer: X=-3
Step-by-step explanation:
2(5x+3)-6x=7x+30+5x
10x+6-6x=7x+30+5x
4x-12x=30-6
-8x=24
-x=3
x=-3
Answer:
<u>D) x² - y = 10x + 25 + y</u>
Step-by-step explanation:
A relation only becomes a function if each x-value only has a single y-value as the answer.
<u>Evaluating</u>
- A and B cannot be the answers as each value will get 2 answers
- C will also not be the answer as y² means at least 2 answers will be given
- <u>D</u> is the best option as each inputted x-value will get an answer of a single y-value
