The slope of the line perpendicular to 4x - 6y = - 60 is (-3/2).
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is
y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.
We know lines perpendicular to each other have slopes that are negative reciprocals of each other.
Given line is 4x - 6y = - 60 ⇒ - 6y = - 4x - 60 ⇒ y = (2/3)x + 10.
Now the line perpendicular to it will have a slope of (-3/2).

Why were goods planned to become obsolete?
A. So that the company would become known for quality goods
B. So that people would keep buying new things
C. So that companies could protect their brand
D. So that people could save as much money as possible
Answer: B
Step-by-step explanation: B. So that people would keep buying new things
Goods are often planned to become obsolete in order to encourage people to continue buying new things. This can be done by intentionally designing products with a limited lifespan or by using materials that are prone to wear and tear. Companies may also release new versions of products or discontinue support for older models in order to encourage consumers to upgrade to the latest version. By making their products become obsolete, companies can create a sense of urgency for consumers to keep buying new things and maintain their sales.
Find the value of x.
The triangles are similar triangles. Then the value of the variable 'x' will be 6.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
Similar triangles are shown below.
We know that the ratio of the corresponding sides of similar triangles remains constant. Then the equation is given as,
(6x - 1) / 15 = 14 / 6
Simplify the equation, then we have
(6x - 1) / 15 = 14 / 6
(6x - 1) / 5 = 7
6x - 1 = 35
6x = 36
x = 6
The triangles are comparable triangles. Then, at that point, the worth of the variable 'x' will be 6.

Now we have three angles in the image and their sum will be 360°, and the angles are :
68° 90° yNow, 68° + 90° + y = 360°
=> 158° + y = 360°
=> y = 360° - 158°
=> y = 202°
Hence, y = 202° is the answer.
An international company has 13,500 employees in one country. If this represents 19.6% of the company's employees, how many employees does it have in total?
Round your answer to the nearest whole number.
The required number of employees does it have in total is 68877.
What is percentage?A percentage is a part of an entire communicated as a number somewhere in the range of 0 and 100 as opposed to as a small portion. Something is all 100%, a big part of it is 50%, none of something is zero percent. To decide a rate, you partition the piece of the entire by the actual entire and duplicate by 100.
According to question:Let total population of the company be X
So,
19.6% of x = 13500
x(19.6/100) = 13500
X = 13500×100/19.6 = 68877 employees

Answer:
Lyric ran faster.
Step-by-step explanation:
When you plot y = 5x, you can trace a certain point to see which value is higher. When I plotted y = 5x and chose the point when x = 8, y = 40 for Kira, and for Lyric, at x = 8, y = 80. Since the y coordinate (distance) is higher, Lyric ran faster.
Lyric ran faster than Kira, since they were travelling a longer distance when comparing to Kira in the same period of time.
Step-by-step explanation:You may use the following logic to analyze this situation. Theoretically, the faster runner will have traveled a longer distance at any given point in time different than 0 when comparing to the other runner. Therefore, let's randomly pick a point in time to see who had traveled the longer distance.
The time we'll evaluate will be 4 seconds.
1. Evaluating the function to find Kira's traveled distance at 4 seconds.
For this, simply substitute the "x" by the number "4" in the given equation for Kira:
[tex]y=5(4)\\ \\y=20[/tex]
Conclusion: Kira had traveled a total distance of 20 yards, 4 seconds after starting the race.
2. Evaluating the function to find Lyric's traveled distance at 4 seconds.
To evaluate the graph, we'll have to draw a line where x=4 sits and then find the value of "y" the function returns. Check the attached images in order to see this process.
Conclusion: Lyric had traveled a total distance of 40 yards, 4 seconds after starting the race.
3. General conclusion.
After 4 seconds Kira traveled 20 yards;
After 4 seconds Lyric traveled 40 yards.
Conclusion: Lyric ran faster than Kira, since they were travelling a longer distance when comparing to Kira in the same period of time.

Step-by-step explanation:
Question 12Find the slope of the line by substituting two points from the given table into the slope formula.
Define the points:
Let (x₁, y₁) = (2, 7)Let (x₂, y₂) = (3, 13)[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{13-7}{3-2}=\dfrac{6}{1}=6[/tex]
Substitute the found slope and point (2, 7) into the point-slope formula to create an equation of the line:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-7=6(x-2)[/tex]
[tex]\implies y-7=6x-12[/tex]
[tex]\implies y=6x-5[/tex]
Question 17Given:
f(4) = 3f(0) = -2Therefore, two points on the line are:
(4, -3)(0, -2)The y-intercept is the y-value when x = 0.
Therefore, the y-intercept of the line is -2.
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
Substitute the y-intercept and the point (4, 3) into the slope-intercept formula and solve for m to find the slope:
[tex]\implies y=mx+b[/tex]
[tex]\implies -3=m(4)-2[/tex]
[tex]\implies -1=4m[/tex]
[tex]\implies m=-\dfrac{1}{4}[/tex]
Therefore, the equation of the line is:

Option A satisfy the equation after simplification that is y(y-1) / 3(y+1) when the equation that is 36y / (y²- 2y+1) ÷ 12y² / (y²-1)
Given that,
We have to simplify the equation that is
36y / (y²- 2y+1) ÷ 12y² / (y²-1)
We know that,
We have to divide the equations,
36y / (y²- 2y+1) ÷ 12y² / (y²-1)
We can write in multiplication form that is
36y / (y²- 2y+1) × (y²-1) / 12y²
Now we can divide the 36y by 12 y² we get 3/y
3(y²-1)/ y(y²- 2y+1)
We can write the y²-1 as (y-1)(y+1) and by formula y²-2y+1 as (y-1)²
3(y-1) (y+1)/ y (y-1)²
Now we can divide
3(y+1)/ y(y-1)
So we can see in the options
Therefore, Option A satisfy the equation after simplification that is y(y-1) / 3(y+1) when the equation that is 36y / (y²- 2y+1) ÷ 12y² / (y²-1)

If the interest from the certificate of deposit was $800 more than the interest from the savings account, how much did Casey invest in each account?
Savings:
Certificate of Deposit:
The amount that Casey invested in the savings account is $10,000 and the amount Casey invested in the certificate of deposit is $60,000.
How much was invested in the savings account and the certificate of deposit?0.01c - 0.02s = $800 equation 1
c + s = $70,000 equation 2
Where:
c = amount invested in the certificate of deposit s = amount invested in the savings accountMultiply equation 2 by 0.01:
0.01c + 0.01s = 700 equation 3
Subtract equation 3 from equation 1:

Divide both sides of the equation by 0.01:
s = 100 / 0.01
s = 10,000

The relation between base length and height is: f(x) = 48/x
What is parallelogram?
A parallelogram is a straightforward quadrilateral in Euclidean geometry that has two pairs of parallel sides. A parallelogram has opposite sides that are facing one another and opposite angles that are of equal size.
By the values given in the table, for base length and height of the parallelograms, you can notice that base length increases 1 units, so you have 1, 2, 3, 4, 5.
For height you can notice that while base length increase 1 unit, height decreases by a factor of 1/x, just as follow:
1 - 48
2 - 24
3 - 16
4 - 12
5 - 8
The relation between base length and height is:
f(x) = 48/x
where f(x) is the height and x is the base length. In fact, you have:
f(1) = 48/1 = 48
f(2) = 48/2 = 24
f(3) = 48/3 = 16
f(4) = 48/4 = 12
