Answer:
when a system of equation has no solution it means that both X's are 0
If it is on a graph then two lines would be parallel to each other
Step-by-step explanation:
for example
-6x +7y= -6x+12y
automatically you would add six to the negative six and you would not have any X's. so it has no solution
-6x +7y= -6x+12y
+6 +6
-------------------
7y=12y
Hopefully you understand what no solution is
have a great day

Which word describes the slope of the line?
Answer:
rate of change
Step-by-step explanation:
Answer:
"rise over run" or "rate of change"
Step-by-step explanation:
"Slope" itself is "rise over run", or how quickly the line moves up or down relative to the x-axis as the value of x changes.
A gradient is really just another name for slope, not a description OF a slope.

I am something people love or hate. I change peoples appearances and thoughts. If a person takes care of them self I will go up even higher. To some people I will fool them. To others I am a mystery. Some people might want to try and hide me but I will show. No matter how hard people try I will Never go down. What am I?
Only one color, but not one size,
Stuck at the bottom, yet easily flies.
Present in sun, but not in rain,
Doing no harm, and feeling no pain.
What is it?
Answer:
The first riddle is Age. Some people love their age, some people hate their age. Age can change appearances and thoughts because as you mature you view things differently. If you take care of yourself, you will become die older than most people. Some people are fooled by age, they think someone is older or younger than they really are. Some people don't know someone's age, so it is a mystery. Some people try and hide their age. Age never decreases.
The second riddle is a shadow. A shadow is only one color, but it can be any shape or size. Shadows are stuck at the bottom, but it easily moves. Shadows appear in the sun, but not when it is raining because of the clouds. Shadows do no harm, and they can't feel anything.

Since starting a new recycling plan, Hannah's office recycles 2 kilograms of paper each
week. How many weeks will it take Hannah's office to recycle a total of 8 kilograms of
paper?
Answer:
4
Step-by-step explanation:
Known:
Every week Hannah's office recyles 2 kilograms of paper
1 week = 2 kg of paper
To find a rate at which the office recyles paper divide the unit of measurement (kg) by a unit of time (weeks)
So:
2 kg/ 1 week = 2 kg of paper recycled per week
We want to know how many weeks it will take to recycle 8 kg.
Think of it this way.
if you divide kg by kg/week the kg cancel out and you get the unit week.
So divided 8 kg by the rate we discovered (2 kg/week) and you shall get the answer 4 weeks.
Write an equation perpendicular to x - 4y = 20 that passes through the point (4, -3)
Answer:
y = - 4x + 13
Step-by-step explanation:
In order to do this problem you would need a whole new equation, but you will use what is given to you:
instead of going with:
x - 4y = 20
Turn it into y = mx + b form, also known as slope-intercept form:
x - 4y = 20
-x = -x
_________
- 4y = 20 - x
Then divide both sides by - 4:
[tex]\frac{-4y}{-4} = \frac{-x + 20}{-4}[/tex]
You will then get:
y = [tex]\frac{1}{4}x - 5[/tex]
From this equation we will only need the slope!
m || = [tex]\frac{1}{4}[/tex]
(This slope is for parallel)
but if you want perpendicular to the slope, then we need the negative reciprocal!
Negative reciprocal is a flipped version of the value that is negative, for example:
2 = [tex]-\frac{1}{2}[/tex]
Because [tex]\frac{2}{1}[/tex] = 2
Now we will find the perpendicular slope which is:
m ⊥ = - 4
Now substitute this slope into slope intercept form:
y = mx + b
(-3) = -4(4) + b
(Take away parentheses)
-3 = -16 + b
(Move - 3 to the other side, by making it positive, but what you do to one side, you do to the other)
= -13 + 6
(Move - 13 to the other side, by make - 13 into +13)
+13 = +13
________
13 = b
(This is you b, also known as you intercept)
Your answer is:
y = -4x + 13

Explain the difference between parallel and perpendicular lines in terms of their slopes. What form of equation of a line is easiest to determine slope?
Answer:
Parallel lines have the same slope, while perpendicular lines have completely opposite slopes. So a line has a slope of 2, a parallel line would have a slope of 2, and a perpendicular line would have a slope of -1/2. The easiest form to identify the slope is standard form because it shows the slope within the equation with out having to solve the equation or convert it into another form.
Use the diagram at the right to determine x and y. AB and CD are
straight lines.

y=-0.6
Step-by-step explanation:
I might be wrong but that's what I got.
Answer:
6 1/3 or 6.333333. . .
Step-by-step explanation:
Original Equation:
2(y - 4) + 4y = 11 + 3y
Use distributive property.
2 x y = 2y
2 x (-4) = -8
Plug these values back into the equation:
2y - 8 + 4y = 11 + 3y
Add 8 to both sides
2y + 4y = 19 + 3y
Add 2y and 4y together
6y = 19 + 3y
Subtract 3y from both sides
3y = 19
Divide both sides by 3

Thomas rented a bus so he and his friends could go to a concert. He had to pay a flat fee of $40 for the bus plus an additional $0.70 per mile. If he paid a total of $104.40, how many miles in total was the trip?
Answer:
so if Thomas payed $40 for the bus we have to find what he payed not including the $40 bus fee.
so we have to subtract 40 from the total price of $104.40.
the equation is 104.40-40=?
104.40-40=$64.40 payed outside the bus fee.
now we have to figure out how many times .70 fits into 64.40
the equation would be 64.40/.70 which means we are dividing 64.40 by .70
so 64.40/.70=92
Thomas and his friends traveled a total of 92 miles to go to the concert.
