Answer:
4y + (y − 1) = 29
(2y + 3) − 4 = 9
4y − y + 1 = 13
Step-by-step explanation:
We will have to check each equation for the given values of y.
So,
1. (2y + 3) − 4 = 9
For y=4
[2(4)+3]-4=9
(8+3)-4=9
11-4=9
7=9
Not true for 4
For y=5
[2(5)+3]-4=9
(10+3)-4=9
13-4=9
9=9
True for 5
2. 4y − y + 1 = 13
For y=4
4(4)-4+1=13
16-4+1=13
13=13
True for 4
3. 4y + (y − 1) = 29
As we have already used 4 and 5 we will check for 6 and onwards
For y=6
6(4)+(6-1)=29
24+5=29
29=29
So the equations in decresing order of y that make them true are:
4y + (y − 1) = 29
(2y + 3) − 4 = 9
4y − y + 1 = 13 ..
Answer:
9. No
10. Yes
Step-by-step explanation:
The first one is not, since you have (3, 3) and (3, 9). In a function, each x maps to a single y.
The second one is since every x appears only once.
