The guess-and-test strategy may be made easier by using the choices.
A. 38 sixth graders ----> 57 - 38 = 19 . There are 19 seventh graders. This option already satisfy the condition that the number of sixth graders should be twice that of the seventh graders. There is no need to test for the remaining choices. The answer is letter A.
Answer:
ez the domain his the first number and the range is the second. so the domain here is 0,5,1 do not write two same numbers like 0 and 0 and the range is 5,2,-4 and again do not write 5 twice
Step-by-step explanation:
0,5,1 is the domain i could be wrong lol

Whenever you want to write the equation of a parallel line through some point (h, k), you can ...
- remove any added constant in the original given equation
- replace x with (x-h)
- replace y with (y-k)
- rearrange the resulting equation to the form required by the problem.
Using this formula here, we get
... 2(y +5) = 3(x -2)
Your answer form requires you solve this for y.
... 2y + 10 = 3x -6 . . . . . eliminate parentheses
... 2y = 3x -16 . . . . . . . . subtract the constant on the left (10)
... y = (3/2)x -8 . . . . . . divide by 2
