Answer:
a = 241
b = 71
Step-by-step explanation:
a + b = 312 (#1)
a - b = 170 (#2)
(#1) + (#2) = 2a = 482.
a = 482 / 2 = 241.
b = 312 - 241 = 71.

2
4
9
10
Answer:
A: 2
Step-by-step explanation:
EDGE 2021
Considering that the magnitude of the complex number x is of 13, a possible value of b is of 2.
What is a complex number?A complex number is modeled by:
z = a + bi.
In which:
a is the real part.b is the imaginary part.In this problem, the number is:
x = 3 + bi.
It's magnitude is given by:
[tex]|x| = \sqrt{3^2 + b^2}[/tex]
Then:
[tex]\sqrt{3^2 + b^2} = \sqrt{13}[/tex]
[tex]3^2 + b^2 = 13[/tex]
[tex]b = \pm \sqrt{4}[/tex]
[tex]b = \pm 2[/tex]
A possible value of b is of 2.

A deck of 40 cards contains 20 blue and 20 red cards. Each color has cards numbered 1 to 20.
Which events are independent? Choose all that apply.
Answer:
A red 5 is chosen from the deck. The card is put back into the deck and the a red card is chosen.
Step-by-step explanation:
An independent event is one whose outcome is not dependent on any other event. There are two types of cards in the deck. If a red card is selected it will be from the series 1 - 20, if the card is put back into deck and then again a red card is selected it will be again from the series 1 - 20. This is an independent event since its outcome is same irrespective of the events.
This is an independent event since its outcome is the same irrespective of the events.
What are independent and dependent variables?Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on the other.
If a variable is taking its values independently of any visible direct cause, then that variable is called an independent variable.
The variables that take their values based on some other variables' values are called dependent variables.

A large store has a warehouse it uses for storage. Trucks back up to the loading dock where merchandise is unloaded, sorted, and stacked in the correct area of the warehouse. The large shelves in the storage area are 17 feet 8 inches apart so the forklift machines can operate between the shelves. Is that distance greater than or less than 216 inches?
Answer:
The distance is less than 216 inches.
Step-by-step explanation:
Each feet has 12 inches.
The large shelves in the storage area are 17 feet 8 inches apart
So, in inches, this distance is of:
17*12 + 8 = 212
This distance is less than 216 inches.
the area of a room is 55.929 square meters if its width is 5.43 meters, what is its length
Answer:
10.3m
Step-by-step explanation:
area of a rectangle is width times length, so you have to rearrange the equation
55.929 ÷ 5.43 = 10.3
Answer:
10.3 meters
Step-by-step explanation:
Area = length x width
55.929 = ? x 5.43
Divide 5.43 from 55.929
55.929/5.43 = 10.3 meters
Check = 10.3 x 5.43 = 55.929

Answer:
[tex]y = -2x -1[/tex]
Step-by-step explanation:
Given
Passes through: (0, -1)
Parallel to: y = -2x + 7
Required
Determine the line equation
If the line is parallel to y = -2x + 7, then it has the same slope as y = -2x + 7.
For an equation of form: [tex]y = mx + b[/tex]
The slope is m
By comparison:
[tex]m = -2[/tex]
So, the slope of the extorted is -2.
The equation is then calculated using:
[tex]y = m(x - x_1)+ y_1[/tex]
[tex]y = -2(x - 0)-1[/tex]
[tex]y = -2(x )-1[/tex]
[tex]y = -2x -1[/tex]

Evaluate −nz−z2−2z when n=3. Simplify your answer.
Answer: n=
−z2−5
z
Step-by-step explanation:
Let's solve for n.
(−n)(z)−z2−2=3
Step 1: Add z^2 to both sides.
−nz−z2−2+z2=3+z2
−nz−2=z2+3
Step 2: Add 2 to both sides.
−nz−2+2=z2+3+2
−nz=z2+5
Step 3: Divide both sides by -z.
−nz
−z
=
z2+5
−z
Answer:
-z^2-5z
Step-by-step explanation:
To evaluate a polynomial at a given value, we substitute the given value for the variable and then simplify using order of operations. We are given n=3, so we substitute 3 for n in the polynomial −nz−z2−2z and simplify as follows.
−nz−z2−2z
−(3)z−z2−2z
−3z−z2−2z
