Answer: Y = 3/8
Step-by-step explanation:
You can either use the rise/run method or subtract 2 points from the line to get the slope. You can do the rise/run method by starting at a point that is on the corner of the square and keep counting how many spaces you have to go until you get to the next even point. This number will be on the bottom, then count up until you get to that even point,this amount of spaces this takes will be on top. Since there are only 2 visible points on this graph,I will use the other method. You can use either the y1-y2/x1-x2 formula or do this
8,3
0,0
8,3
Remember,the y goes on top! Our slope is 3/8,also since the y intercept is the orgin/0,0 we don't need to add it at the end. I hope this helps and wasn't too complicated!
y = 3/8(x) is the equation that represents the proportional relationship in this graph, for y in terms of x.
What is proportional?In mathematics, two sequences of numbers, frequently experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, known as the coefficient of proportionality or proportionality constant.
If corresponding elements in two sequences have a constant product—also known as the coefficient of proportionality—then the two sequences are inversely proportional.
This definition is frequently broadened to include associated varying amounts, also known as variables.
We can see that when y = 1.5, then x = 4
And when y = 3, x = 8
Putting the value in slope form
y - y1 = m(x - x1)
3 - 1.5 = m(8 - 4)
1.5 = m(4)
m = 1.5/4
m = 3/8
Now simply we put the value in y-intercept form
y - 3 = 3/8(x - 8)
y = 3/8(x) - 3 + 3
y = 3/8(x)

Multiply .15 * 245 =$36.75 ok that’s the first discount!
Second discount is 10% so turn 10% into a decimal (by dividing your percentage by 100) = .10
Multiply .10*245= $24.50 <- that’s your second discount

Which graph shows the solution to the system of linear equations?
y equals one third x
x + 3y = −6
Answers
Answer:So let's start by guesstimating the slopes:
the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.
Next let's look at the solution: the two lines intersect at the point (1, -1).
**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)
A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2
B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense
C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations
D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1
So the correct answer is:
C) y = 2x - 3 and y = −2x + 1

Answers
Answer:
Step-by-step explanation:

the percentage of people that finished the survey is 93.6%, given.
this percentage as a fraction is p, (being the people) = 93.6/100, so, p = 93.6/100.
you then multiple the fraction 93.6/100 by 10, which is: p = 936/1000. then, reduce the fraction.
p = 117/125.
the fraction can’t be reduced any further, so that’s your answer.

Carter wants to ride his bicycle 28.7 miles this week. He has already ridden 17 miles. If he rides for 3 more days, write and solve an equation which can be used to determine mm, the average number of miles he would have to ride each day to meet his goal.
Answers
Answer: Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal.
Step-by-step explanation:
Finding the answer to this problem isn't too complicated, and all we have to do is make and solve an equation. First, we know how many miles Carter wants to ride his bicycle (this is what our equation will be equal to), and how many miles he's completed already (we add that to how many he has to do daily). We also know how many days he has left to complete this goal (multiply the number he has to do daily by three).
All we have to do now is construct a basic equation:
17 + 3x = 28.7
Let's move the 17 over to the other side of the equation. To do that, subtract 17 from both sides.
3x = 28.7 - 17
3x = 11.7
This gives us the amount of miles Carter still has to ride - in total. To find out how many miles he has to ride daily, we just divide 3 from both sides.
3x/3 = 11.7/3
x = 3.9 (miles - don't forget the units!)
Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal. Hope this helps!
