Answer:
9y⁴−9y
Step-by-step explanation:
Subtract 8y48y4 from 5y45y4.
6y4−y−8y−(−3y4)6y4-y-8y-(-3y4)
Multiply −3-3 by −1-1.
6y4−y−8y+3y46y4-y-8y+3y4
Simplify by adding terms.
Add 6y46y4 and 3y43y4.
9y4−y−8y9y4-y-8y
Subtract 8y8y from −y-y.
9y⁴−9y
3 1/4 - 1 7/8
First, subtract the whole numbers (3 - 1 = 2):
= 2 1/4 - 7/8
Convert 1/4 to 2/8:
= 2 2/8 - 7/8
Borrow 1=8/8 from the 2:
= 1 10/8 - 7/8
Subtract 7/8 from 10/8:
= 1 3/8
The answer is 1 3/8
Alternatively, use improper fractions:
3 1/4 = 13/4 = 26/8
1 7/8 = 15/8
26/8 - 15/8 = 11/8 = 1 3/8
The function of 5 (or y when x is 5) can not be determined with this little information.
Could I have a picture of the model which is shown?
