To compute the double integral of f(x, y) = 99xy over the domain D, we need to set up the limits of integration for both x and y.
Since the domain D is not specified, we will assume it to be the entire xy-plane.
Thus, the limits of integration for x and y will be from negative infinity to positive infinity.
Using the double integral notation, we can write:
∫∫ 99xy dA = ∫ from -∞ to +∞ ∫ from -∞ to +∞ 99xy dxdy
Evaluating this integral, we get:
∫ from -∞ to +∞ ∫ from -∞ to +∞ 99xy dxdy = 99 * ∫ from -∞ to +∞ ∫ from -∞ to +∞ xy dxdy
We can solve this integral by integrating with respect to x first and then with respect to y.
∫ from -∞ to +∞ ∫ from -∞ to +∞ xy dxdy = ∫ from -∞ to +∞ [y(x^2/2)] dy
Evaluating the limits of integration, we get:
∫ from -∞ to +∞ [y(x^2/2)] dy = ∫ from -∞ to +∞ [(y/2)(x^2)] dy
Now, integrating with respect to y:
∫ from -∞ to +∞ [(y/2)(x^2)] dy = (x^2/2) * ∫ from -∞ to +∞ y dy
Evaluating the limits of integration, we get:
(x^2/2) * ∫ from -∞ to +∞ y dy = (x^2/2) * [y^2/2] from -∞ to +∞
Since the limits of integration are from negative infinity to positive infinity, both the upper and lower limits of this integral will be infinity.
Thus, we get:
(x^2/2) * [y^2/2] from -∞ to +∞ = (x^2/2) * [∞ - (-∞)]
Simplifying this expression, we get:
(x^2/2) * [∞ + ∞] = (x^2/2) * ∞
Since infinity is not a real number, this integral does not converge and is undefined.
Therefore, the double integral of f(x, y) = 99xy over the domain D (the entire xy-plane) is undefined.

Step-by-step explanation:
x = -4/5 = -0.8
Answer:
x = −0.8
Step-by-step explanation:
−2.7 + x = −3.5
1.) Simplify both sides of the equation
x − 2.7 = −3.5
2.) Add 2.7 to both sides
x − 2.7 + 2.7 = −3.5 + 2.7

The set of side lengths that could represent a right triangle is
12 ft, 10 ft, and 8 ft.
Option D is the correct answer.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To determine which of the given sets of side lengths could represent a right triangle, we can apply the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).
Using this theorem, we can check each of the given sets of side lengths to see if they satisfy this condition:
6 ft, 5 ft, 4 ft
6² + 5² = 36 + 25 = 61
4² = 16
Since 61 is not equal to 16, this set of side lengths does not represent a right triangle.
8 ft, 7 ft, 6 ft
8^2 + 7^2 = 64 + 49 = 113
6^2 = 36
Since 113 is not equal to 36, this set of side lengths does not represent a right triangle.
10 ft, 8 ft, 6 ft
10^2 + 8^2 = 100 + 64 = 164
6^2 = 36
Since 164 is not equal to 36, this set of side lengths does not represent a right triangle.
12 ft, 10 ft, 8 ft
12^2 + 10^2 = 144 + 100 = 244
8^2 = 64
Since 244 is equal to 64 + 180, this set of side lengths does represent a right triangle.
Therefore,
The set of side lengths that could represent a right triangle is 12 ft, 10 ft, and 8 ft.

Solve the equation, and choose the type of solution you
found.
2x + 8 = 2(x + 4)
Answer:
All real numbers are solutions
Step-by-step explanation:
2x + 8 = 2(x + 4)
~Simplify right side
2x + 8 = 2x + 8
~Subtract 8 to both sides
2x = 2x
~Divide 2 to both sides
0 = 0

r/1000=7, algebra, got confused and this one is weird to do. (personally)
Answer:
r = 7000Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
r/1000-(7)=0
Step by step solution :
STEP1:
r
Simplify ————
1000
Equation at the end of step1
r
———— - 7 = 0
1000
STEP 2
Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 1000 as the denominator :
7 7 • 1000
7 = — = ————————
1 1000
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
r - (7 • 1000) r - 7000
—————————————— = ————————
1000 1000
Equation at the end of step 2
r - 7000
———————— = 0
1000
STEP 3
When a fraction equals zero :
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
r-7000
—————— • 1000 = 0 • 1000
1000
Now, on the left hand side, the 1000 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
r-7000 = 0
Solving a Single Variable Equation:
Solve : r-7000 = 0
Add 7000 to both sides of the equation :
r = 7000
One solution was found :
r = 7000
