Are the following lines parallel, perpendicular, or neither? -4x-5y=-4 and 10x-8y=-1
Answers
Answer:
perpendicular
They are neither parallel nor perpendicular as they have different slopes.
First line equation in form of y = mx +c is:
y = (4x-4)/5
and second line equation is :
y= -((10x+1)/8)

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibels?
Answers
Answer:
The numbers of measure of music played are 1 and 7
Step-by-step explanation:
Given
[tex]s = 10|x - 4| + 50[/tex]
Required
Solve for x when s = 80
Substitute 80 for x
[tex]80 = 10|x - 4| + 50[/tex]
Subtract 50 from both sides
[tex]80 - 50= 10|x - 4| + 50 - 50[/tex]
[tex]30= 10|x - 4|[/tex]
Divide through by 10
[tex]\frac{30}{10}= \frac{10|x - 4| }{10}[/tex]
[tex]3= |x - 4|[/tex]
Reorder
[tex]|x - 4| = 3[/tex]
This can be split into
[tex]x - 4 = 3[/tex] or [tex]x - 4 = -3[/tex]
Solve for x
[tex]x = 4 + 3[/tex] or [tex]x = 4 - 3[/tex]
[tex]x = 7[/tex] or [tex]x = 1[/tex]
Hence:
The numbers of measure of music played are 1 and 7

2(5x+9) = 10x+18
3(4x+2) = 12x+6
5(3x+7) = 15x+35
Does this anwser your question?!?
Answer:
See below
Step-by-step explanation:
For there to be infinitely many solutions, the equations have to be the same on the left side of the equation as on the right
3x+6 = 3 ( x+2)
As you can see when we distribute
3x+6 = 3x+6
Another example
2x+3 = x+ x+ 1+2
When we combine like terms
2x+3 = 2x+3
A third example
2x -5 +2x -6 = 7x-3x - 15+4
Combine like terms
4x -11 = 4x -11
Marc mixes blue and yellow paint to make his favorite shade of green, which he'll use to paint his house. He has 14 cans of blue paint and 20 cans of yellow paint when he starts. He wants the same green color every time he mixes, so the amounts of blue and yellow must always be proportional to the original mixture. On day 1, he mixes 4 cans of blue and 6 cans of yellow. On day 2, he mixes 6 cans of blue and 9 cans of yellow. 1. In simplest form, what is the ratio of blue paint to yellow paint in the mixture? Type your answer in the space below.
Answers
Answer:
The answer is 0,66
Step-by-step explanation:
Assuming he gets the exact same shade of green everyday, the ratio of blue to yellow for Marc's green color is 0,66 because 4 / 6 and 6 / 9 give the same results when calculated in decimal.

Satellites in low-Earth orbit circle around our planet at about 4.72 miles per second. A satellite that relayed a phone text message traveled 16.52 miles before the message reached the recipient. How long did it take the text to go from phone to phone? It took the text seconds to go from phone to phone.
Answers
Answer: 3.5
Step-by-step explanation:
Divide 16.52 by 4.72. It equals 3.5.
Using the speed - distance relationship, the time it'll take for the text to travel from phone to phone is 3.5 seconds.
Given the parameters :
Transmission speed = 4.72 miles per second Distance traveled = 16.52 milesRecall :
Time = Distance ÷ SpeedTime taken = (16.52 / 4.72) = 3.5 seconds.
The time it took the text to travel from phone to phone is 3.50 seconds.

Answer:
-18w+2
Step-by-step explanation:
6*-3w=-18w
1/3*6=2
The resultant expression is -18w + 2 which could represent the expanded form by using the distributive property.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given in the question as follows:
6(-3w+1/3)
We have to expand the given expression by using the distributive property.
As per the question, we have
⇒ 6(-3w+1/3)
Apply the distributive property of multiplication,
⇒ 6 × (-3w)+ 6 × (1/3)
⇒ -18w + 6/3
⇒ -18w + 2
Therefore, the resultant expression is -18w + 2.
