The owners of an apartment building bought it new and then 5 years later sold it for $165000. They calculated that the building appreciated $2000 per year while they owned it.
we have to find a linear function that describes the value of the building over time, if a is the age of the apartment building
write a linear function is in slope-intercept form:
y= mx+b
Here, x is the independent variable, and y is the dependent variable. Also, the slope of the line, m, represents some kind of constant rate. Finally, b, the y-intercept represents some sort of starting value for our dependent variable.
165000= $2000*5+b
$165000= $10000+b
$155000=b
f(a)=2000a+155000
therefore f(a)= 2000a +155000 is a linear function that describes the value of the building over time, if a is the age of the apartment building

Find a solution to the linear equation 13x +y =26 by filling in the bows with a valid value of x and y.
Answers
The solution to the linear equation are x = 2 - y/13 and y = 26 - 13x.
It is required to find the solution to the linear equation.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.
Given:
The equation is
13x + y = 26
We have to find the value of x and y .
According to given question we have
13x + y = 26
Subtract 13x from both sides we get,
y = 26 - 13x
Subtract y from both sides
13x = 26 - y
Divide through by 13
x = 2 - y/13
Therefore, the solution to the linear equation are x = 2 - y/13 and y = 26 - 13x.

A mural measures 145 feet long by 190 feet high. Find the ratio of the height to the perimeter of this mural.
Answers
The ratio of height to perimeter of mural is 19:67.
The perimeter of mural will be calculated by the formula -
Perimeter = 2 × (length + breadth)
So, finding the perimeter using the mentioned formula. Keep the values of length and breadth in formula to calculate the perimeter of mural.
Perimeter = 2 × (145 + 190)
Performing addition of values in bracket
Perimeter = 2 × 335
Performing multiplication
Perimeter = 670 feet
Ratio = Height : Perimeter
Ratio = 190 : 670
Cancelling zero to find the ratio
Ratio = 19 : 67
Hence, the ratio of the height to the perimeter of this mural is 19:67.

what is the direction of vector v if it ends at (-3,-10)
Answers
The direction of the vector v in standard position is approximately 253.301°.
What is the direction of a given vector?
Vectors in rectangular form present the change of each of the two variables parallel to orthogonal axes. Each point is described by the following definition:
v = (Δx, Δy) (1)
And the direction of a vector is equal to this inverse trigonometric function:
θ = tan⁻¹ (Δy / Δx) (2)
If we know that Δx = - 3 and Δy = - 10, then the direction of the vector is:
θ = tan⁻¹ (- 10 / - 3)
θ = tan⁻¹ (10 / 3)
θ ≈ 253.301°

Answers
Answer:
7.5 inches
Step-by-step explanation:
15 ft long and 10 ft wide becomes 3/2 when converted into a ratio
we now have 3/2 and five inches
3 is 1.5*2
5*1.5 is 7.5
Answer:
7.5in
Step-by-step explanation:
If the original room's dimensions are (15ft x 10ft). Then the new scaled-down version is (?ft x 5in) we can set up a ratio of 10/5 = 2 to find that the scale from the room to the drawing is being shrunk by a factor of 2. So if you take 15/2 you will get your final answer of the new length of 7.5in!

Answers
The equation, [tex] \frac{2 \cdot x + p}{q} = \frac{2 \cdot x + q}{p} [/tex], gives;
When p = q, the number of solutions is infinite.
When p ≠ q, the equation has no solution
How can the given equation be evaluated?The given equation is presented as follows;
[tex] \frac{2 \cdot x + p}{q} = \frac{2 \cdot x + q}{p} [/tex]
If p = q, we have;
[tex] \frac{2 \cdot x + q}{q} = \frac{2 \cdot x + q}{q} [/tex]
[tex] \frac{2 \cdot x + p}{p} = \frac{2 \cdot x + p}{p} [/tex]
Therefore, the equation has an infinite number of solutions when p = Q
If p ≠ q, and x = 3, we have;
[tex] \frac{2 \cdot x + p}{q} = \frac{2 \times 3 + p}{q} = \frac{6 + p}{q} [/tex]
[tex] \frac{2 \cdot x + q}{p} = \frac{6 + q}{p} [/tex]
[tex] \frac{6 + p}{q} [/tex] = \frac{6 + q}{p} [/tex]
6•p + p² = 6•q + q²
However;
p ≠ q
Therefore;
6•p ≠ 6•q
p² ≠ q²
6•p + p² ≠ 6•q + q²
Which gives;

The equation is not defined when p ≠ q

Eighty meters of fencing is available to enclose the rectangular garden of Mang
Gustin. Give a function A that can represent the area that can be enclosed in
terms of x.
Answers
A function that can represent the area that can be enclosed in terms of x is 40x-x².
Given that Eighty meters of fencing is available to enclose the rectangular garden of Mang Gustin.
Area is defined as the amount of space that can be used within a flat surface or the surface of a solid. Perimeter is defined as a continuous line that forms a boundary to define a two-dimensional shape.
Let the length of garden, l=x
and the given perimeter, p=80
As we know, perimeter of rectangle is P=2(l+b).
Now, we will substitute the values and find the value of b, we get
80=2(x+b)
Now, we will divide both sides by 2, we get
80/2=2(x+b)/2
40=x+b
Further, subtract x from both sides, we get
40-x=x+b-x
40-x=b
Now, we will find the area of rectangle by using the formula A=lb.
Substitute the values in above formula, we get
A=x(40-x)
A=40x-x²
Hence, the area that can be enclosed in terms of x is 40x-x².
