because perpendicular lines have the opposite slope
m=-1 and (-6,12)
help pls
Answer:
y = -x +6
Step-by-step explanation:
i honestly didn't know what form you wanted so i put it in slope-intercept form for you :D
formula for slop-intercept form:
y=mx+b
12 = -1 ( -6 ) + b -----> filled in the m, x and y
12 = 6 + b -----> do PEMDAS
12 - 6 = b -----> moved 6 to the other side to isolate variable
6 = b -----> you found the y-intercept
y = -x + 6 ------> fill the equation in :D
Phone Company 1 charges a flat rate of $25.00 a month for local calling,
and $0.05 per minute for each long distance call. Phone Company 2
charges a flat rate of $20.00 a month for local calling, and $0.10 per
minute for long distance calling. After how many minutes of long distance
calling do the phone companies charge an equal amount?
A 50 minutes
B. 100 minutes
C. 200 minutes
D. 300 minutes
Answer:
B = 100
Step-by-step explanation:
25 + .05x = 20 + .10x
5 = .05x
100 = x

Add 2x4 - 6x3 + 5x to the difference between 9x3 + 8x2 - 2 and 4x4 - 2x2 + 8x - 5.
Simplify (x3 + 3x2 + 5x – 4) – (3x3 – 8x2 – 5x + 6)
The first thing I have to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a "1" in front of the parentheses, to help them keep track of the minus sign.
Here's what the subtraction looks like, when working horizontally:
(x3 + 3x2 + 5x – 4) – (3x3 – 8x2 – 5x + 6)
(x3 + 3x2 + 5x – 4) – 1(3x3 – 8x2 – 5x + 6)
(x3 + 3x2 + 5x – 4) – 1(3x3) – 1 (–8x2) – 1(–5x) – 1(6)
x3 + 3x2 + 5x – 4 – 3x3 + 8x2 + 5x – 6
x3 – 3x3 + 3x2 + 8x2 + 5x + 5x – 4 – 6
–2x3 + 11x2 + 10x –10
And here's what the subtraction looks like, when going vertically:
x
3
−(3x
3
+3x
2
−8x
2
+5x
−5x
−4
+6)
In the horizontal addition (above), you may have noticed that running the negative through the parentheses changed the sign on each and every term inside those parentheses. The shortcut when working vertically is to not bother writing in the subtaction sign or the parentheses; instead, write the second polynomial in the second row, and then just flip all the signs in that row, "plus" to "minus" and "minus" to "plus".

80ft^2 since for the rectangle part of the shape is 6x10. The triangular part of the shape is (4x10)/2.
Therefore, that's (60)+(40/2)=60+20. Resulting in 80ft^2
Two rectangular fields with identical shapes and areas are to be fenced side by side. The total area enclosed is 8 mmmm2 and the perimeter for all the fencing is 16 miles. Find the possible dimensions of one of the fields (2 possible answers).
Answer:
3 mi and [tex]\dfrac{4}{3}[/tex] mi, 1 mi and 4 mi
Step-by-step explanation:
Length of one of rectangles = x
Breadth of one of the rectangles = y
Total enclosed area = [tex]8\ \text{mi}^2[/tex]
Fence available = 16 miles
Total area is given by
[tex]2xy=8\\\Rightarrow y=\dfrac{4}{x}[/tex]
Perimeter of the fence
[tex]2\times 2x+3y=16\\\Rightarrow 4x+3y=16\\\Rightarrow 4x+3\dfrac{4}{x}=16\\\Rightarrow 4x+\dfrac{12}{x}=16\\\Rightarrow 4x^2-16x+12=0\\\Rightarrow x=\frac{-\left(-16\right)\pm \sqrt{\left(-16\right)^2-4\times \:4\times \:12}}{2\times \:4}\\\Rightarrow x=3,1[/tex]
If [tex]x=3[/tex]
[tex]y=\dfrac{4}{x}=\dfrac{4}{3}[/tex]
If [tex]x=1[/tex]
[tex]y=\dfrac{4}{x}=4[/tex]
The possible values of length and breadth are 3 mi and [tex]\dfrac{4}{3}[/tex] mi, 1 mi and 4 mi respectively.

Avinash bought an electric iron for rupees 900 and sold it for a gain of 10% he sold another electric iron at 5% loss which was bought for rupees 12000 on the transaction he has
a) Profit of Rs 75
b) Loss of Rs 75
c) Profit of Rs 30
d) Loss of Rs 30 Pls I need this in 2 min Pls are you helping I WILL MARK AS BRAINLIEST PLLLLLSSSSSSSSSSSS DUDE ITS A 5 MARKS
Note: Cost of second iron must be 1200 instead of 12000.
Given:
Cost of first electric iron = 900
Grain on first electric iron = 10%
Cost of second electric iron = 1200
Loss on second electric iron = 5%
To find:
The correct statement for the given problem.
Solution:
We have,
Cost of first electric iron = 900
Grain on first electric iron = 10%
Profit on first iron is
[tex]900\times \dfrac{10}{100}=90[/tex]
Cost of second electric iron = 1200
Loss on second electric iron = 5%
Loss of second iron is
[tex]1200\times \dfrac{5}{100}=60[/tex]
Now, profit is 90 and loss is 60. Profit is more than loss.
Exact profit = Profit - Loss
Exact profit = 90 - 60
Exact profit = 30
Therefore, Avinash get a profit of Rs. 30 on the transactions. Hence, the correct option is c.

For parties of six or more, a restaurant adds a 20% gratuity (or tip). Ifa
dinner bill for a large party comes to $148.25, find the total dinner bill with
tip.
Answer:
$247.37
Step-by-step explanation:
The total dinner bill with a tip for the large party is $177.90.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
The gratuity for a large party is 20% of the bill, so we can calculate the gratuity by multiplying the bill by 0.2.
Gratuity = bill x 0.2
Gratuity = 148.25 x 0.2
Apply the multiplication operation, and we get
Gratuity = 29.65
To find the total bill, we add the gratuity to the original bill.
Total bill = bill + gratuity
Total bill = 148.25 + 29.65
Apply the addition operation, and we get
Total bill = $177.90
Hence, the total dinner bill with a tip for the large party is $177.90.

Line a and b are perpendicular lines.If line a is represented by y=s/t x+10 and line b is represented by y=q/r -4 where s,t,q and r are integers and t and r are not equal to zero which statement is always true
Answer:
The options are not shown, so i will answer in a general way.
First, for a line of the form:
y = a*x + b
All the perpendicular lines will have a slope of -(1/a), then we can write a general perpendicular line as:
y = -(1/a)*x + c.
In this problem we have the perpendicular lines:
y=(s/t)*x+10
y = (q/r)*x - 4
Because those lines are perpendicular, we must have that:
(q/r) = -(1/(s/t)) = -(t/s)
q/r = -t/s
and we knew that s, t, q and r are integers (where t and r can not be equal to zero), and because of this relation, where we can see that in the denominator at the right we have the integer s, we can conclude that s can not be zero (we can not divide by zero).
And we know that t and s are both different than zero, then:
-t/s ≠ 0.
This means that:
q/r ≠ 0
And from this, we can conclude that q is different than zero.

5(x + 7) = 6(x - 5)
Solve for the variables SHOW WORK
Answer:

Given
18n + 12 = 27n + 3 5(x + 7) = 6(x - 5)Solving for variables
1
18n + 12 = 27n + 3 18n - 27n = 3 - 12-9n = -9n = -9/-9n = 12
5(x + 7) = 6(x - 5)5x + 35 = 6x - 305x - 6x = -30 - 35-x = -65x = 65Answer:
18n + 12 = 27n + 3
12-3=27n-18n
9=9n
n=9/9=1
5(x + 7) = 6(x - 5)

How far apart are Clay and Jason?
Answer:They are 600 feet apart from each other
Step-by-step explanation:
Answer:
600
Step-by-step explanation:
the 200 since its below the surface it would become negitive and 400 - -200 would turn into 400 + 200 and that would be 600 :)
