Which orders pair is the solution to the system of equations
Answer: C) (12, -14)
Step-by-step explanation:
I am going to solve by elimination.
Start by subtracting one equation from the other
[tex]y=-x-2\\-(y=-\frac{1}{2} x-8)\\0=-\frac{1}{2} x+6[/tex]
Now solve for x
[tex]0=-\frac{1}{2} x+6\\0-6=-\frac{1}{2} x+6-6\\-6=-\frac{1}{2} x\\(-6)(-2)=(-2)(-\frac{1}{2} x)\\12=x[/tex]
Now sub in x into one of the equations to find the value of y

How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
What is domain and range of a function?Domain is the set of values for which the given function is defined.
Range is the set of all values which the given function can output.
We're given that:
Time spent by Vlad on history homework = 20 minutesTime spent by Vlad on math homework (x math problems) = 2 minutes on each problemy = time he spent on doing overall homeworkThen we have:
y = time on math homework + history homework
y = 2 +2 +2 ... (x times) + 20 minutes
[tex]y = 2x + 20[/tex]
x is "number of math problems". Thus, x can be 0,1,2,... These numbers are called non-negative integers(or integers greater or equal to 0) or whole numbers.
y is the time taken, but we see that
y = 2 times (non-negative integer) + 20
y = positive integer times non-negative integer + positive integer
Thus, we have:
y = non-negative integer + positive integer = positive integer
Thus, y assumes positive integral values only (in minutes).
Also, y is always going to be at least 20 (as history homework is going to take 20 minutes, even if math homework is nill ).
Thus, the expression for y is y = 2x +20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20

step by step explanation -
well , the question asks us to find the difference between the two terms given as mixed fractions ~
tho it's not that difficult to simplify a problem in mixed fraction , but solving the problem by first converting it to an improper fraction reduces the risk of mistakes ! so let's do the question by that way ~
[tex]4 \frac{4}{5} - 3 \frac{2}{5} \\ \\ converting \: into \: improper \: fraction \: we \: get \\ \\ \implies \: \frac{5 \times 4 + 4}{5} \: \: - \: \: \frac{5 \times 3 + 2}{5} \\ \\ \implies \: \frac{24}{5} \: \: - \: \: \frac{17}{5} \\ \\ since \: the \: denominators \: are \: same \: we \: can \: simply \: subtract \: the \: terms \\ \\ \implies \: \frac{7}{5} [/tex]

Alex is 12 years older than George.
Carl is three times older than Alex
The sum of their ages is 68
Find the ratio of George's age to Carl's age to Alex's age.
Answer:
George : Carl : Alex = 1 : 12 : 4
Step-by-step explanation:
let a = Alex's age in years
let g = George's age in years
let c = Carl's age in years
Given:
Alex is 12 years older than George⇒ a = 12 + g
⇒ g = a - 12
Given:
Carl is three times older than Alex⇒ c = 3a
Given:
The sum of their ages is 68⇒ a + g + c = 68
Substitute the first two equations in the last equation and solve for a:
⇒ a + (a - 12) + 3a = 68
⇒ 5a - 12 = 68
⇒ 5a = 80
⇒ a = 16
Substitute the found value of a into the other equations to find g and c:
⇒ g = 16 - 12 = 4
⇒ c = 3(16) = 48
Therefore:
Alex = 16 years oldGeorge = 4 years oldCarl = 48 years oldRatio
George : Carl : Alex = 4 : 48 : 16
Reduce by dividing by 4 → 1 : 12 : 4

Find the surface area of the figure. Be sure to show all of your work and steps in solving for your answer.
Answer:
The surface area of a figure is the sum of all the sides that consist of it.
Let's first find the base's area, using the formula for the area of a rectangle, L · W:
9(6)
= 54 is the area of the base.
Now let's find the entire front side of this figure's area and double it so we get both the areas of the front and back side (using the formula for the area of a rectangle):
4(9)[bottom front rectangle] + 4(5)[upper front rectangle]
36 + 20
= 56, now double that area to get the area of both the front and back side:
56(2)
= 112 is the area of both the entire front and back side of this figure.
Now let's figure out the area of the right whole side of this figure then double it so we get both the areas for the left and right sides.
But, if we look at the middle rectangle to the right and left sides, we can see that there is no value, so let's find the value first.
The total length across the figure is 9 inches.
And we are given that the rectangle above intersects with the total length, so let's exclude that from 9 inches.
9 - 4 = 5, so now the total length of the two rectangles beside the above rectangle is 5.
But we want to find the value of one side, so divide 5 by 2.
5/2 = 2.5 inches.
Now let's find the whole entire area of the right side to this figure.
5(6)[upper right rectangle] + 2.5(5)[flat middle right rectangle] + 6(4)[bottom right rectangle)
30 + 12.5 + 24
= 66.5, now double that area to get both the area of the right and left side.
66.5(2)
= 133, is the area of both the right and left side of this entire figure.
Finally, we add all those areas together to get the surface area:-
54 + 112 + 133
= 299 inches is the surface area for this figure.
Answer:The surface area of a figure is the sum of all the sides that consist of it.
Let's first find the base's area, using the formula for the area of a rectangle, L · W:
9(6)
= 54 is the area of the base.
Now let's find the entire front side of this figure's area and double it so we get both the areas of the front and back side (using the formula for the area of a rectangle):
4(9)[bottom front rectangle] + 4(5)[upper front rectangle]
36 + 20
= 56, now double that area to get the area of both the front and back side:
56(2)
= 112 is the area of both the entire front and back side of this figure.
Now let's figure out the area of the right whole side of this figure then double it so we get both the areas for the left and right sides.
But, if we look at the middle rectangle to the right and left sides, we can see that there is no value, so let's find the value first.
The total length across the figure is 9 inches.
And we are given that the rectangle above intersects with the total length, so let's exclude that from 9 inches.
9 - 4 = 5, so now the total length of the two rectangles beside the above rectangle is 5.
But we want to find the value of one side, so divide 5 by 2.
5/2 = 2.5 inches.
Now let's find the whole entire area of the right side to this figure.
5(6)[upper right rectangle] + 2.5(5)[flat middle right rectangle] + 6(4)[bottom right rectangle)
30 + 12.5 + 24
= 66.5, now double that area to get both the area of the right and left side.
66.5(2)
= 133, is the area of both the right and left side of this entire figure.
Finally, we add all those areas together to get the surface area:-
54 + 112 + 133
= 299 inches is the surface area for this figure.
