Answer:
Step-by-step explanation:
A: The charge of each electron is -1, so the charge of three electrons is -3. Removing something is denoted by a negative sign. The expression that represents the removal of three electrons from each of four atoms is (-3)(-4).
B: (-3)(-4) = (-1)(3)(-1)(4) = (-1)(-1)(3)(4) = 12
The net change in the charge for the group of atoms is 12 (or +12); that is, the charge of the atoms increases by 12.
C: Adding two electrons to each of six atoms results in a net change in charge of (-2)(6). Removing two protons from each of six atoms results in a net change in charge of (2)(-6).
D: (-2)(6) = (-1)(2)(6) = (-1)(12) = -12
(2)(-6) = (2)(6)(-1) = (12)(-1) = -12
E: The products are the same: -12.
F: If the signs of the numbers are the same, the product is positive. If the signs of the numbers are different, the product is negative.

y = 5x + 2 and y = 5x – 1 parallel, perpendicular, or neither
Answer:
Parallel
Step-by-step explanation:
Parallel lines have the same slope, in this equation it is a slope of 5.
The given lines are parallel in nature.
What is slope?Numerical measure of a line's inclination relative to the horizontal.
Equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation.
Given:
y = 5x + 2 and y = 5x – 1
The slope for line 1 is 5.
and, the slope for line 2 is 5.
For, perpendicular line the slope of both lines are negative inverse relation.
But here the slope of both line are same which have parallel nature.
Hence, both lines are parallel in nature.

POLYNOMIALS QUESTION!!!
Answer:
The new area of the smaller rectangle is 16 - x² units²
Step-by-step explanation:
The dimensions of the small rectangles are 2 + x and 2 - x
∵ The length of the small rectangle is 2 + x units
∵ The length is adding by 2 units
∴ The new length = 2 + x + 2 = 4 + x units
∵ The width of the small rectangle is 2 - x units
∵ The width is adding by 2 units
∴ The new width = 2 - x + 2 = 4 - x units
∵ Area of the rectangle = length × width
∴ The new area of the smaller rectangle = (4 + x) × (4 - x)
→ Simplify it by multiplying the 2 brackets
∵ (4 + x)(4 - x) = (4)(4) + (4)(-x) + (x)(4) + x(-x)
∴ (4 + x)(4 - x) = 16 + (-4x) + 4x + (-x²)
→ Remember (+)(-) = (-)
∴ (4 + x)(4 - x) = 16 - 4x + 4x - x²
→ Add the like terms
∴ (4 + x)(4 - x) = 16 - x²
∴ The new area of the smaller rectangle is 16 - x² units²

Line v passes through point (6, 6) and is perpendicular to the graph of y = 34x – 11. Line w is parallel to line v and passes through point (–6, 10). Which is the equation of line w in slope-intercept form?
A. y = 34x + 2
B. y = –34x + 2
C. y = 43x + 2
D. y = –43x + 2
A B C OR D WHICH ONE
Answer:
y = (1/34)x + 346/34
Step-by-step explanation:
We are told that; Line v passes through point (6, 6) and is perpendicular to the graph of y = 34x – 11
Now, for a line to be perpendicular to another, it means the slope of one will be the negative reciprocal of the other.
Intercept of y = 34x – 11 will be; m = 34
Thus, slope of v is; -1/34
Now, Line w is parallel to line v and passes through point (–6, 10).
Since the slope of v = -1/34, it means the slope of w will be -1/34 because parallel lines have the same slope.
Thus, using slope intercept form, the equation of line w is;
y - 10 = (-1/34)(x - (-6))
y - 10 = x/34 + 6/34
Multiply through by 34 to get;
34y - 340 = x + 6
34y = x + 346
y = (1/34)x + 346/34
what is the difference between -0.4 and 44.4?
Answer:
44.8
Step-by-step explanation:
Answer: The difference between two numbers can be obtained by subtracting the smaller number from the bigger number. Here, - 0.4 is the smaller number, and 44.4 is the larger number. Therefore, the difference between the two is 44.4 - (- 0.4)

In this case, the opportunity cost for (refurbishing the gym, upgrading the computer lab, or getting new instruments.) was ( upgrading the new computer lab hardware, getting new equipment, or getting new instruments?
Answer:
getting new instrument
Explanation:
Note that the term opportunity cost refers to the value or the cost of not selecting/benefitting from the other alternative option.
Comparing both budgets, it is observable that the budget for computer lab hardware was increased by 5%; and that of musical instruments was reduced by 5% according to The Northville School Board order of preference (importance).
Thus, we can say that the board decided to forgo some of the amount spent on musical instruments, but decided to increase spending on computer hardware.
Answer:
In this case, the opportunity cost for upgrading the computer lab hardware was getting new instruments.

sum n=3 ^ infty (2n+5)
find the series shown
=====================================================
Explanation:
We're adding terms in the form (2n+5)
The first term is when n = 3, so
2n+5 = 2*3+5 = 6+5 = 11
The next term is when n = 4, so
2n+5 = 2*4+5 = 8+5 = 13
The next term is when n = 5, so
2n+5 = 2*5+5 = 10+5 = 15
And so on
This means,
[tex]\displaystyle \sum_{n=3}^{\infty} (2n+5) = 11+13+15+17+\ldots[/tex]
which matches with choice C. The three dots indicates the pattern goes on forever.
-------------------
Choice B does not have these dots, so that's why choice B is not the answer. If we replaced the infinity symbol with 7, then choice B would be the answer.
I.e,
[tex]\displaystyle \sum_{n=3}^{7} (2n+5) = 11+13+15+17+19[/tex]
Write an integer that represents the situation. Do not type any units, labels, or spaces or your answer will be scored as incorrect. Death Valley California is the lowest land in the United States, and portion of it lies two hundred eighty two feet below sea level.
Answer:
-282
Step-by-step explanation:
Given
[tex]Position = 282ft[/tex]
Required
Represent this with an integer.
Since, it is below the se level.
The integer is:
[tex]Integer = Sea\ Level - Position[/tex]
Where:
[tex]Sea\ Level=0[/tex]
[tex]Integer = Sea\ Level - Position[/tex]
[tex]Integer = 0 - 282[/tex]
[tex]Integer = -282[/tex]

What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
here, we have,
Given:
G(x) = F(x) + 5
As, the transformation takes place so there is a positive five.
The value of the function for a given x is the vertical position of the point on the graph.
Adding 5 to the function value shifts the graph up 5 units.
Hence, The graph of G(x) is the graph of F(x) shifted 5 units up.

You play basketball At your schools indoor stadium. You have two payment options. Option A is to buy a membership card for $20 and pay $2 each time you go to the gym, t. Option B is to pay $4 each time you go. After how many trips to the gym will the cost be the same?
Answer:
10 trips
Step-by-step explanation:
Let the number of trips to the gym be represented by t
Option A is to buy a membership card for $20 and pay $2 each time you go to the gym.
$20 + $2× t
20 + 2t
Option B is to pay $4 each time you go.
$4 × t
= 4t
After how many trips to the gym will the cost be the same?
Option A = Option B
20 + 2t = 4t
Collect like terms
20 = 4t - 2t
20 = 2t
t = 20/2
t = 10 trips.
After 10 trips, the gym cost will be the same.
