Answer:
x= 2/3 -1/3y or x= -1/3y + 2/3
Step-by-step explanation:
3x + y= 2 (subtract the y to get 3x by itself)
3x= 2-y (divide both sides by 3 to get x by itself)
x= 2/3 - 1/3y
if an ordered pair is a solution, it should satisfy the equation.
see the first option
, if you put $x=4$ and $y=12$
you'll get $12=12$ which is true.
now the last option, $y=8-x$ put $x=4$ and $y=12$
$12=8-4\implies 12\ne4$ thus it is not a solution.
So option 4 is correct
2 minutes - 1 minute = 1 minute
7 square feet - 3,5 square feet = 3,5 square feet
ANSWER:The rate of change is 3,5 square feet per minute.
The answers are C and D. C because the more answers you get correct, the less you can get incorrect. D because if a whole lot of dogs walk through a garden the damage to the flowers is likely to be massive!
Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 3, 5 ] , thus
f(b) = f(5) = - 26 ← value of y for x = 5 from table
f(a) = f(3) = - 10 ← value of y for x = 3 from table
average rate of change = = = - 8 → A
