Write an equation of a line that passes through the point Z (6, – 2) and is perpendicular to the line y=-1/3x + 2
Answers
Answer:
y = 3x - 20
Step-by-step explanation:
First, we have to find the slope of the equation. We can do by taking the opposite reciprocal of the slope of the original line.
The opposite reciprocal of-1/3 is 3/1 or 3.
So, the slope of our equation will be 3. Our equation so far is:
y = 3x + b.
To find b, or the y-intercept of the line, we can simply substitute the given coordinates into the equation. If we replace x with 6 and y with -2 and solve the equation, we can find the value of b.
-2 = 3(6) + b
-2 = 18 + b
-2 - 18 = b
b = -20
So the equation is,
y = 3x -20.
To check our equation, we can again substitute the coordinates into the equation and solve. If both sides are equal, then the equation is correct.
-2 = 6(3) - 20
-2 = 18 - 20
-2 = -2
The two lines are perpendicular if a 90° angle is formed when they
intersect.
The equation of the line that passes through point Z(6, -2) and is perpendicular to the line [tex]y = -\dfrac{1}{3} \cdot x + 2[/tex] is ; y = 3·x - 20
Reason:
The equation of the required line is, y = 3·x - 20
The given point is Z(6, -2)
Perpendicular to the line, [tex]y = -\dfrac{1}{3} \cdot x + 2[/tex]
Solution:
The slope of a line perpendicular to another line having a slope, m, is [tex]-\dfrac{1}{m}[/tex]
The slope of the given line is [tex]-\dfrac{1}{3}[/tex]
The slope of the perpendicular line is therefore;
[tex]m = -\dfrac{1}{\left(-\dfrac{1}{3}\right)} = \dfrac{3}{1} = 3[/tex]
The point and slope form of the equation of the given line is therefore;
y - (-2) = 3·(x - 6)
y + 2 = 3·x - 3×6 = 3·x - 18
y = 3·x - 18 - 2 = 3·x - 20
y = 3·x - 20
The equation of the line that passes through point Z(6, -2) and is perpendicular to the line [tex]y = -\dfrac{1}{3} \cdot x + 2[/tex] is therefore;
y = 3·x - 20

Answers
Answer:
the answer is -1
Step-by-step explanation:
Answer: x = 0
Step-by-step explanation: Firstly, set them equal to each other.
7x - 1 = 6x - 1
Now, subtract 6x from both sides:
x - 1 = -1
Add 1 to both sides:
x = 0
And if you need to know what type of function it is, it is an infinite function because if you plug in 0:
7(0) - 1 = 6(0) - 1
You get:
-1 = -1
If both sides are the same, it is an infinite function.

-SGO
Answers:
a) 80% nonfiction
b) 1200 fiction, 4800 nonfiction
=========================================
Explanation:
part (a)
We only have two choices: fiction or nonfiction
If 20% are fiction, then 100% - 20% = 80% are nonfiction.
The two percentages 20% and 80% add to 100% to represent all the books.
---------------------
part (b)
20% = 20/100 = 0.20
20% of 6000 = 0.20*6000 = 1200
we have 1200 fiction books
6000-1200 = 4800
and we have 4800 nonfiction books
Note how
80% of 6000 = 0.80*6000 = 4800
which helps confirm part (a)

please answer quickly!!!!!!!!!!!!
Answers
Answer:
A. 5*(-8)*2=-80
B. Forgot about the signs
Step-by-step explanation:
Product of Signed Integers
The product of two integers with like (same) signs is positive. The product of two integers with different signs is negative.
A.
Alex is simplifying the product 5*(-8)*2. It can be done in any order, for example, let's multiply 5*(-8) first.
The numbers have different signs, so the product is negative and 8*5 =40, thus: 5*(-8)=-40.
Now we finish the operation multiplying (-40)*2. They have different signs, thus the result is negative and (-40)*2=-80, thus:
5*(-8)*2=-80
B.
If Alex found the opposite of the correct product, that is, 80 is more likely to have been the result of forgetting about the signs. He probably just multiplied the numbers regardless of their signs.
In one month, the median home price in the west fell from $203,400 to $192,300. Find the percent decrease
Answers
(i’m not sure what to round it to)
subtract 192,300 from 203,400 to find the amount of change
(= 11,100)
then divide that amount from the original price (203,400)
then multiply that number by 100 to get a percent
finally round to a reasonable percent
11,100/203400= 5.46%
It decreased by 5.46%

dollars each week.
a. Write an inequality to

description.
b. How much does Lia
need in sales to make
her goal?
Answers
Answer:
Step-by-step explanation:
To write the inequality, we need to first caculate the amount of money that Lia would ACTUALLY earn each week and compare that to her goal of $600.
We cannot actually get the amount of money that Lia would get because we don't know her sales so we will represent the sales with a X.
450+ X(5%). -This the amount of money she would egt from her sales. We need to also figure out 5% of 450 to solve the next part of the equation. That is $22.5. 600-450=150/22.5= 6.6666- which is about 7 sales.

The equation of the line shown in the graph would be, [tex]y = \dfrac{4}{5} x - 3[/tex]
Hence, option 1 is true.
Given that;
Two points on the line are (5, 1) and (0, -3).
Used the concpet of the equation of the line,
The equation of a line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, [tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Now,
Since, The equation of line passes through the points (5, 1) and (0, -3)..
So, We need to find the slope of the line.
Hence, the slope of the line is,
[tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
[tex]m = \dfrac{(- 3 - 1)}{(0 - 5)}[/tex]
[tex]m = \dfrac{(- 4)}{( - 5)}[/tex]
[tex]m = \dfrac{(4)}{( 5)}[/tex]
Thus, The equation of the line with slope 4/5 is,
[tex]y - 1 = \dfrac{4}{5} (x - 5)[/tex]
[tex]y - 1 = \dfrac{4}{5} x - 4[/tex]
[tex]y = \dfrac{4}{5} x - 4 + 1[/tex]
[tex]y = \dfrac{4}{5} x - 3[/tex]
Therefore, The equation of the line will be;
1) [tex]y = \dfrac{4}{5} x - 3[/tex]
So, option 1 is true.
