1. 3x - 3y = 9  

to find the x or y intercept, multiply the other variable that you are not tryng to find by 0  

3x - 3(0) = 9             3(0) - 3y = 9

3x = 9                       -3y = 9

3x/3 = 9/3                 -3y/-3 = 9/-3

x = 3                           y = -3


2. I did the same thing for the rest

x = 6     y = -2


3.   x = 2.5     y = -5


4.  x = -4  y = -2/3

Answer:

B

Step-by-step explanation:

A. these simply to 21 + 7x and 21 + 3x

  • this one is incorrect because the 7x and 3x are different

B. these simplify to 10 + x and 10 + x

  • this is the correct one since they are exactly the same

C. these simplify to 21x and 7x + 21

  • these two are not the same because one expression has only a number with a variable but the other one has a number with a variable <em>and </em>another number

D. these simplify to  \frac{7}{3-x}  and  \frac{7}{x-3}

  • in subtraction, the order of the 3 and the x matters, so the equations are not the same
  • example: 6 - 4 = 2 but 4 - 6 = -2

41) you have a 40 day period
two visits with +75 centimeter growth each
3 visits with +6 each
in total 2*75+3*6=150+18=168
divide this by 40 days to get the average: 168/40=4.2 centimeters per day or 1.65 inches/day

3x20
2x15
1x13

the mode is the most common value: 20$ which exists 3 times
