1.
X = 0
2x + 1 = 0
X = 0
X = - ½ (Because we brought the numbers from one side to the other)

Not sure for number 2.
It will move but won't change shape or size.
This is the concept of business mathematics, given an inflation rate of 3%, that has modeled the price of items using the function c(x)=1.03x, the cost of the refrigerator in 3 years will be as follows;
cost after 1 year:
c(1)=1.03*1500
=1545
cost after 2 years
c(2)=1.03*1545
=1591.35
the cost after 3 years will be:
c(3)=1.03*1591.35
=$1,639.09
8 + 5 by removing 2 from the 5 to leave 3, add this 2 to the 8 to make 10 then add the 3 to the 10 to give 13.
Step-by-step explanation:
33+22+90=145
180-145=35
