Step-by-step explanation:
f(x) = y = -1/2 × sqrt(x + 3), x >= -3
-2y = sqrt(x + 3)
4y² = x + 3
x = 4y² - 3
and now we need to rename x to y and y to x to make it a "normal" function :
y = 4x² - 3
since in the original function x >= -3, this gave us y <=0.
and therefore (remember the x of the inverse function actually stands for the y of the original function) the limit for the inverse function is x <= 0.
so, again, the full answer is
f^-1(x) = 4x² - 3, x <= 0
If you have the profit formula which is profit (x1, x2) = 110x1 + 150x2, then by substitution of the given point (x1, x2) = (0, 30), you can find the profit at the corner point profit (0.30 ) = 110 (0) + 150 (30) = 4500.Therefore the profit will be $ 4500
Answer:
Step-by-step explanation:
To solve this problem, first you have to use the slope formula of 
.
y2= (-7)
y1=6
x2=4
x1(-6)
Solve.
Therefore, the correct answer is -13/10.
Answer:
500 miles
Step-by-step explanation:
81-11 is 70. 70 divided by .14 is 500 so that's 500 miles she can bike.
