Step (1) is incorrect. To divide by a number means to multiply by the reciprocal. In step (1) they did not convert the polynomial into its reciprocal.
Answer:
y = 4
Step-by-step explanation:
We are to find an equation of a line that passes through (2,4) and has a slope of 0.
Taking another point (x,y) on the line.
Slope of a straight line = change in y ÷ change in x.
i.e 
y - 4 = 0(x - 2)
y - 4 = 0
y = 4 (the equation of our line)
Brazil population: 1.907×
Mexico population 1.123×
To find how much more the population was in Brazil than in mexico, you would subtract the Brazil population to Mexico's population:
The
's would not cancel out because they are representing further decimal places that aren't written, so you would subtract 1.907 and 1.123.
1.907 - 1.123= 0.784
Brazil's population is 0.784×
larger than Mexico.
Answer: Substraction property
Step-by-step explanation:
-94=12n+2
12n+2=-94
12n+2-2=-94-2
12n=-96

n=-8
