Step-by-step explanation:
If the values in the table below model a proportional relationship, what is the equation for the function?
Given:
The table represents a proportional relationship.
To find:
The equation of the function.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
where, k is the constant of proportionality.
From the given table it is clear that the function passes through (2,1). So, the equation must be satisfied by the point (2,1).
Putting x=2 and y=1 in (i), we get
[tex]1=k(2)[/tex]
[tex]\dfrac{1}{2}=k[/tex]
Putting [tex]k=\dfrac{1}{2}[/tex], we get
[tex]y=\dfrac{1}{2}x[/tex]
Therefore, the correct option is A.
Solve for x: 3 (x - 3) + 8x = 5(2x + 1)
Answer:
x = 14
Step-by-step explanation:
3 (x - 3) + 8x = 5 (2x + 1)
FOIL: 3x - 9 + 8x = 10x +5
Move all the x terms to one side and all the constants to the other:
3x + 8x - 10x = 5 + 9
Combine like terms: x = 14

Step-by-step explanation:
If you know that a < b, and both a and b and positive numbers, then what just be true about the relationship between the opposites of these numbers? Explain.
Answer:
-a > -b
Step-by-step explanation:
On a number line, every number (except zero, the origin) has both a magnitude and a direction (left or right, negative or positive).
The magnitude is how far the number is from the origin. 10 is further from zero than 6 is. And -10 is alos further from zero than -6 is.
If a < b and a,b are both positive, that means a and b are both on the right-hand side of the number line, and a is closer to the origin than b. The magnitude of a is smaller than that of b.
So if we switch the sign son both a and b, they both become negative and go over to the left-hand side of the number line. But their magntidues do not change, so a is still closer to the origin than b. Since b is now a negative number, further to the left than a, it is smaller than a.
Example: let a = 3 and b =5.
It is true that 3 < 5.
But it is NOT true that -3 < -5. It's the other way around!
-5 < -3
So, if a < b, then -a > -b.

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y = 2x - 3
Now, putting x=0
y= -3
and, x= 1
y= 2(1)-3
y = -1
and, x= 2
y=2 (2)- 3
y = 1
Hence, the coordinates of line is (0, -3), (1, -1) and (2, 1)

How many square feet of outdoor carpet will
we need for this hole?
?
3 ft
Ift
2 ft
4 ft
2 ft
12 ft
Answer:
40 sq feet
Step-by-step explanation:
(im bad at explaining)
1 x 2 = 2 sq ft
3 x 2 = 6 sq ft
4 x 12 = 48 sq ft
2 sq ft + 6 + sq ft = 8 sq ft
48 - 8 = 40
The amount of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle) = 40 ft².
What is the Area of a Rectangle?Area of a rectangle = lenght × width.
The amount of square feet of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)
The amount of square feet of outdoor carpet needed = 12 × 4 - (3 × 2 + 2 × 1)
The amount of square feet of outdoor carpet needed = 48 - (6 + 2)
The amount of square feet of outdoor carpet needed = 40 ft²

How can you tell if a graph is function or not
Answer:
If the vertical line intersects the graph in at most one point, then the given graph represents a function. If the vertical line intersects the graph in more than one point, then the given graph does not represent a function.
I HOPE IT HELPS
TAKE CARE
Step-by-step explanation:
Answer:
Step-by-step explanation:
For a graph to be a function, there must not be more than one element in the range for each element of the domain.
If x represents the doman, and y represents the range (as usual, in graphing) then each value on the the x-axis should not have more than one point in the graph on it, directly above it, or directly below it. Like if you had a point (5, 7) and also had point (5, -7), that is not a function. The x, 5, has more than one y-value paired with it.
Visually, any vertical line through the graph should not intersect the graph at more than one point. If it does, then the graph is not a function.
This is called the vertical line test.

Find m\angle Am∠Am, angle, A.
Round to the nearest degree.
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA = [tex]\frac{-169+136}{120}[/tex]
cosA = -0.275
A = [tex]\text{cos}^{-1}(-0.275)[/tex]
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.
