Answer:

Step-by-step explanation:
y = 3 - xy
Let x = 1
y = 3 - (1)y
Expand brackets.
y = 3 - y
Add y to both sides.
2y = 3
Divide both sides by 2.
y = 3/2
First we would solve both x’s
3x^2 - 5x
But 3 has the thingy thing (forgot the name haha)
Which means you have to multiply it by itself that many times which would be
3x3=9
So now it would be
9x- 5x = 4x
Which leaves 7 and 4x
Now you may subtract those two
7-4x= 3x

Yasmine's speed is faster than Jermaine's because when you subtract the two numbers, you get 4.5 miles per hour.

Answer:</h3>
-5y +1
<h3>
Step-by-step explanation:</h3>
Let the polynomial to be subtracted be represented by Q. Then you want ...
... (y^2 -5y +1) -Q = y^2
... (y^2 -5y +1) = y^2 +Q . . . . add Q
... (y^2 -5y +1) -y^2 = Q . . . . .subtract y^2
... -5y +1 = Q . . . . . . . . . . . . . simplify
The polynomial to be subtracted is -5y +1.
