Answer: B) FalseThe input x = 5 leads to the two outputs f(x) = 2 and f(x) = 1 (as shown by the green arrows in the attached image). In order to have a function, all of the inputs must lead to exactly one output.
I'm not so good but I think thatmeans r is a different number and its half of 14 so figure out an equation
Answer:
2. option D and 3. option A
Step-by-step explanation:
2. 7 + y = 30
<u>7 - 7</u> + y = <u>30 - 7</u>
y = 23
3. w - 32 = 55
w <u>-</u><u> </u><u>32</u><u> </u><u>+</u><u> </u><u>32</u> = <u>55</u><u> </u><u>-</u><u> </u><u>32</u>
w = 87
Basically the answers you choose are right. Hope this helps, thank you :) !!
Their earnings would be the same after 4 hours
Let the number of hours be x, and the weekly earning be y
So, the given parameters are:
<u>Kimi</u>
- Earnings = $9 per hour
- Weekly allowance = $8
So, the equation for Kimi's weekly earning is:

<u />
<u>Jordan</u>
- Earnings = $7 per hour
- Weekly allowance = $16
So, the equation for Jordan's weekly earning is:

Equate both equations

Collect like terms


Divide both sides by 2

Hence, their earnings would be the same after 4 hours
