Answer:
(1,-5)
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
S^2
SxS
S^(S-1)xS
Any of those should work
Answer:
7x^2+21x+14
Step-by-step explanation:
With this all we have to do is foil:
first outside inside last
first: 7x^2
outside: 14x
inside: 7x
last: 14
we now combine them to
7x^2+14x+7x+14
we add like terms
7x^2+21x+14
Its linear because every thing is equivalent and it will stay that way using any factor
Answer:
He must sell 1390 carrots
Step-by-step explanation:
30x + 300x/30 = 55500
40x = 55500
x = 1387.5
1387.5
multiply 30 by .3 to get $9 for 30 carrots
Then add $3 to this amount to get $12 dollars.
Divide 555 by 12 to get 46 R3.
Multiply 46 by 30 because its 46 bundles of 30 carrots
Then divide the 3 dollars by .3 for each carrot to get 10 carrots
1380+10 = 1390
