Answer: No solutions
Step-by-step explanation: If you solve the problem all the way, you get 0 = 4 which is not valid so there is simply no solution
10 is the initial value, found when x=0. I don't know what you are measuring by "0" and "10" here, so can't be more specific.
Answer:
a: x − 2y = −12
Step-by-step explanation:
the standard form of a line is is usually given as Ax + By = C, so just by deduction you can tell that the correct answer is a.
If you want to do the procedure it would be:
y − 3 = 1/2 (x + 6)
y − 3 = 1/2 x + 3
y - 1/2 x = 3 + 3
y - 1/2 x = 6
(y - 1/2 x = 6) * 2 to get rid of the fraction
2y - x = 12 rearrenge the terms
x - 2y = -12
Carl is incorrect. Dave ate a higher fraction of snack bars, by 0.2 snack bars.
Carl had .5 left of a snack bar.
Dave had .3 left of a snack bar.
Tony had .5 left of a snack bar.
Gary had .0 left of a snack bar.
Tryone had .7 left of a snack bar.
If we add the above snack bars, there is a total of two remaining snack bars, meaning they only ate 12 of 14 snack bars.
