Answer:
80/3 or 26 2/3
Step-by-step explanation:
-2 + y = 9 (subtract y from both sides)
-2 = 9 - y (subtract 9 from both sides)
-2 - 9 = y (multiply both sides by -1)
2 + 9 = y (simplify)
11 = y (substitute)
3x - 7 (11) = 3 (multiply)
3x - 77 = 3 (subtract 3 from both sides)
3x - 80 = 0 (subtract 3x from both sides)
-80 = -3x (multiply both sides by -1)
80 = 3x (divide both sides by 3)
80/3 = x (simplify if needed)
26 2/3 = x
Answer:
see explanation
Step-by-step explanation:
Slope- intercept form is y = mx + c
Rearrange the given inequalities into this form
x + y ≤ 55 ( subtract x from both sides )
y ≤ - x + 55
-------------------------------------------------
60x + 40y > 600 ( subtract 60x from both sides )
40y > - 60x + 600 ( divide all terms by 40 )
y > - x + 15
Answer:
D)
Step-by-step explanation:
In this case, you are looking for the undefine <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>], meaning that there are repetitive x-coordinates. With that being said, you have your answer.
