The domain is the x value of an equation or graph. Since the x is the amount of tomatoes sold, it would have to be any positive value because you can't sell a negative number of tomatoes. (x≥0)

Answer:
y = 3x + 1
Step-by-step explanation:
' y = 3x + 1 ' is a equation of a linear function. The equation is in slope-intercept form. All slope intercept-form lines are linear.
An equation for a linear function has no exponents, no variables in fractions, and no square roots.
Hope this helps.
Multiply the first equation by 4 (so that both equations will have 8x terms) and then subtract:
8x-20y = -24
8x +3y = 68
------------
0 -23y = -92
Now divide both sides by -23:
y = 4
Find x by plugging y=4 into either equation:
8x +3(4) = 68
8x = 68 - 12
8x = 56
x = 7
So the answer is ordered pair is (7,4)
Answer:
8+7d
Step-by-step explanation:
So forest you combine like terms
4+4=8
There are no longer any like terms so your finished product is 8+7d
