OK first change 3 3/4 to an improper fraction and that will give you 15/4. so you got that part right. Next, change the division sign to multiplication. then flip the 1/2 to 2/1. Then multiply 15 times 2 and that will give you 30. Then multiply 4 times 1 and that will give you 4. then you will have an answer of 30/4. Finally, since you a have a big number over a small number you divide 30 by 4 and that will give you 7 1/2. So it turns out that your little cheat sheet is wrong because when you check your answer you should go on Math-way to check it. Also, a little background about me is that I am in 8th grade and I am taking algebra 1 too.

Answer:
108points
Step-by-step explanation:
Let Caleb score be x and that of Mike be y. If Caleb and Mike both score the same amount of points in a game, then x = y.
The total number of option = x+y
Now, If Caleb has fifteen less than the total number of options, then;
x =(x+y)-15
x -(x+y)+15 = 0
x-x-y = -15
-y = -15
y = 15
Also if Mike has twice the total number of points decreased 201, then;
y = 2(x+y)-201
Since y = 15
15 = 2(x+15)-201
15 = 2x+30-201
15 = 2x-171
2x = 15+171
2x = 186
x = 186/2
x = 93
The total number of points they have altogether is x+y
x+y = 15+93
x+y = 108
Hence the total points that they have altogether is 108points
Answer:
A. Yes they do. Both equations have their opposing set of y-intercept. Where equation one has a y-intercept of +7, and equation two, +7.
B. No they do not. Equation one has a slope of +3, while equation 2 has a slope of -4.
C. Yes they do. Equation one represents that of a positive increasing graph, while equation two the opposite, decreasing.
Step-by-step explanation:
You can use the slope formula to identify and graph each equation simply by using y = mx + b. Where y is the the y coordinate, x is the x coordinate, m is the slope, and b is the y-intercept. With this you can start plotting by marking the y-intercept by putting the x as zero and seeing what number you get. In this case, 3x0-7 = -7. Meaning that would be the y-intercept. For the slope, depending on what the x coordinate is, that's how much the graph will increase or decrease whenever the x coordinate changes. Say the x coordinate is 1, so 3x1-7 = 3-7 = -4. Meaning your coordinate would be (1, -4) where you can keep doing this formula on and on to find the y coordinate for what x coordinate you want to find, or make it easier to graph with a ruler on paper once you have enough points.
