Answer:
You can not divide by zero.
The inequality is equivalent to - 20.2 > 0 which is false.
Step-by-step explanation:
We can not divide both sides by zero, because if we divide both sides by zero, then the inequality becomes
⇒ - ∞ > y, which is not possible.
Again, the given inequality is - 20.2 > 0 × y.
We have to multiply y with zero and a product of zero with any term is also zero.
Hence, the inequality becomes - 20.2 > 0.
Therefore, the inequality is equivalent to - 20.2 > 0 which is false. (Answer)
Given x ^2 −3x+2=0
x ^2 −2x−1x+2=0
(Resolving the expression)
x(x−2)−1(x−2)=0 (Taking common factors)
(x−2)(x−1)=0 (Taking common factors)
∴x−2=0 or x−1=0 (Equating each factor to zero)
∴x=2 or x=1
∴2 and 1 are the roots of x ^2 −3x+2=0

Hello!
Let's write some important information contained in the exercise:
• hotdogs: $2.59 (,x,)
,
• hamburgers: $5.29 (,y,)
He needs 11 packages. Let's write it:
• x + y = 11
He spent a total of $39.29. We can write it as:
• 2.59x + 5.29y = 39.29
Now, let's solve these two equations as a linear system:
First, let's isolate x in equation A:
Now, we will replace where's x by 11-y in equation B:
As I called the hamburgers as 'y', we know that he bought 4 packages of hamburgers.
