Answer:
Choice B is correct; (10, 60)
Step-by-step explanation:
For Lisa to make a profit, the function R should assume a value greater than 0;
R > 0
We are to determine the interval of x values for which the above expression will be true.
From the graph, R(x) = 0 when x = 10. As x increases from 10 to 60, the value of R(x) remains positive, that is;
R(x) ≥ 0 for values of x in the interval (10, 60)
The domain that she should use in order to only model selling prices for which she will make a profit is thus;
(10, 60)
Answer:
-2 and 3
Step-by-step explanation:
These two are slopes. All three are technically slopes but a slope of 0 is just a horizontal line.
X:2+(105-275:11):4=28
X:2+(105-25):4=28
X:2+80:4=28
X:2+20=28
X:2=28-20
X:2=8
X=8×2
X=16
Answer:
Step-by-step explanation:
to figure out b we can consider the following formula:
the form of vertex coordinate given by
so according to the question
by order pair we obtain:
now substitute the value of h and a to the formula:
simplify multiplication:
cross multiplication:
divide both sides by -1:
now we need to figure out C to do so substitute -7 for x and -5 for y which yields:
simplify square:
simplify multiplication:
simplify addition:
cancel 49 from both sides:
hence,
