Answer:
Step-by-step explanation:
Alternate forms:
x^2 + y (y + 4) = 5
x^2 + y^2 + 4 y - 5 = 0
Solutions:
y = -sqrt(9 - x^2) - 2
y = sqrt(9 - x^2) - 2
Integer solutions:
x = ± 3, y = -2
x = 0, y = -5
x = 0, y = 1
Implicit derivatives:
(dx(y))/(dy) = -(2 + y)/x
(dy(x))/(dx) = -x/(2 + y)
Answer:
x = 20.8
y = 22.3
Step-by-step explanation:
tan(21) = 8/x
or, x = 8/tan(21)
or, x = 20.8 (rounded to the nearest tenth)
sin(21) = 8/y
or, y = 8/sin(21)
or, y = 22.3 (rounded to the nearest tenth)

The restaurant can make 39 batches.
1,275 divided by 32 is 39.84, since you can't make .84 of a batch, the answer is 39.
Substitute the values of x from each table and see which values fit
For example in table d when x = 40 y = (-3/8)*40 + 75 = 60 which is the result given in table d
The other 2 values also fit table d
Answer is table d.
Set up two inequalities for the absolute value inequality.
First inequality and second inequality: x + y > 1 or x + y < -1
Notice I used or between the inequalities. If your absolute value expression is greater than the constant, it is a disjunction.
Graph the individual inequalities on the same plane and that is your solution.
