Step-by-step explanation:
Simplify the following:
-(3 + 1/3) (-(2 + 7/10))
Hint: | Multiply all instances of -1 in -(3 + 1/3) (-(2 + 7/10)).
(-1)^2 = 1:
(3 + 1/3) (2 + 7/10)
Hint: | Put the fractions in 2 + 7/10 over a common denominator.
Put 2 + 7/10 over the common denominator 10. 2 + 7/10 = (10×2)/10 + 7/10:
(3 + 1/3) (10×2)/10 + 7/10
Hint: | Multiply 10 and 2 together.
10×2 = 20:
(3 + 1/3) (20/10 + 7/10)
Hint: | Add the fractions over a common denominator to a single fraction.
20/10 + 7/10 = (20 + 7)/10:
(3 + 1/3) (20 + 7)/10
Hint: | Evaluate 20 + 7.
20 + 7 = 27:
(3 + 1/3)×27/10
Hint: | Put the fractions in 3 + 1/3 over a common denominator.
Put 3 + 1/3 over the common denominator 3. 3 + 1/3 = (3×3)/3 + 1/3:
27/10 (3×3)/3 + 1/3
Hint: | Multiply 3 and 3 together.
3×3 = 9:
((9/3 + 1/3)×27)/10
Hint: | Add the fractions over a common denominator to a single fraction.
9/3 + 1/3 = (9 + 1)/3:
27/10 (9 + 1)/3
Hint: | Evaluate 9 + 1.
9 + 1 = 10:
10/3×27/10
Hint: | Express 10/3×27/10 as a single fraction.
10/3×27/10 = (10×27)/(3×10):
(10×27)/(3×10)
Hint: | Cancel common terms in the numerator and denominator of (10×27)/(3×10).
(10×27)/(3×10) = 10/10×27/3 = 27/3:
27/3
Hint: | Reduce 27/3 to lowest terms. Start by finding the GCD of 27 and 3.
The gcd of 27 and 3 is 3, so 27/3 = (3×9)/(3×1) = 3/3×9 = 9:

How much is 0 x , where x is any non-zero number? How much is 0 x for any positive power of x? How much is 0 0 ? Explain.
Answer:
Step-by-step explanation:
The value X° where x is non zero number will give a value of 1 because any value raise to the power of zero gives 1.
For example if X = 2, 2° = 1
For the expression 0^x, this will result into zero for any positive power of x. Let x be 3 for example,
0³ = 0×0×0
0³ = 0
Also if x = 4
0⁴ = 0×0×0×0 = 0
Therefore, no matter the value of x, rge value 0^x will return back zero.
For 0^0 this value is an indeterminate function i.e we cannot determine the the value. The value cannot return Amy positive or negative real number on the number line. Hence 0^0 is indeterminate.
The volume of a cube is 729 inches³. How long is each side
Answer:

Two angles are complementary, as shown in the diagram below.
xº
15°
Part A: Use the definition of complementary angles to set up an equation that can be used to solve for the value of c.
Part B: Solve for the value of x. In your final answer, include all of your calculations.
Answer:
A; x + 15 = 90
B: x = 75
Step-by-step explanation:
A: complementary angles are angles that add up to 90 degrees. This means that x and 15, the two angles that are complementary, will add up to 90:
x + 15 = 90
B: For B, you just need to solve the equation for x:
1. x + 15 = 90
2. x = 75
Step 1 is the given equation
In step 2, 15 was subtracted from both sides

A function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set.
Answer:
Yes,
Step-by-step explanation:
Because every "x" Value corresponds to exactly one "y" value.
Yes, the relation is a function.
What is a function?A relation is a function if it has only One y-value for each x-value.
The given relation is {(3,2), (1, -2), (2, -4), (3, -2)}.
We need to check whether the relation is a function or not.
A function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set.
As we observe the given relation three comma two, one comma minus two, two comma minus four comma three comma minus two.
Yes, the given relation is a function because there is no x value is repeated. Every y value has an unique x value.
Hence, the relation is a function.

The perimeter of parallelogram ABCD is 46 inches. What is DA?
3 in.
4 in.
8 in.
19 in.
Answer:
4
Step-by-step explanation:
trust
The value of DA in parallelogram ABCD is 4 inches.
ParallelogramA parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel to each other.
In parallelogram ABCD:
AB = DC, AD = BC
Hence:
8x - 5 = 3x + 10
5x = 15
x = 3 units
AB = 8(3) - 5 = 19 inches
Let y = AD = BC:
AB + BC + DC + AD = perimeter
19 + 19 + y + y = 46
y = 4 inches
The value of DA in parallelogram ABCD is 4 inches.

Which of the following describes the quotient of 4 and -44?
Answer:
the answer to 4 divided by -44 is -11
Step-by-step explanation:
Line b passes through the points (0,5) and (2,-1). Which of the following functions is
parallel to b and contains the point (11,-3)?
Answer:
y = -3x + 30
Step-by-step explanation:
A great website to use for graphing is desmos. You first graph the starting 2 points, turn it into a line connecting it, then make an equation. You should get y = -3x + 5, so when we look for something parallel it should have the same slope. I then put into the graph every equation along with the dot (11,-3) and looked to see which intersected.

Answer:
14/25
Step-by-step explanation:
If the denominators are the same, subtract the numerators.

Write an equation of the line, in the requested forms, that passes through the given point and is perpendicular to the given line. (-8,5) y=4x-4
Answer:
y = (-1/4)x + 3
Step-by-step explanation:
to find the perpendicular slope you just find the reciprocal of 4 which is (-1/4)
then find the y-intercept making the line go through (-8, 5) so you do:
y = (-1/4)x + b
5 = (-1/4)(-8) + b
5 = 2 + b
-2 -2
3 = b
find the value of X and Y if (2x + 3) + i(x – 2y) = 5 – 7i
Answer:
x = 1, y = 4
Step-by-step explanation:
Given
(2x + 3) + i(x - 2y) = 5 - 7i
Equate the real parts on both sides
2x + 3 = 5 ( subtract 3 from both sides )
2x = 2 ( divide both sides by 2 )
x = 1
Equate the coefficients of the imaginary terms
x - 2y = - 7 , that is
1 - 2y = - 7 ( subtract 1 from both sides )
- 2y = - 8 ( divide both sides by - 4 )
y = 4
