Answer:[tex](-7-2)=-3(-3-0)[/tex]
Step-by-step explanation:
First use slope intercept form to find the value of b (the y intercept). The slope intercept formula is
[tex]y=mx+b[/tex]
Since we are given the point (-3,2), we can say that y=2 and x=-3. m=-3. Then we get
[tex]2=-3(-3)+b[/tex]
[tex]2=9+b[/tex]
[tex]b=-7[/tex]
Since we now have the y intercept, we can convert it to a point: (0,-7). Plug this into the point slope equation:
[tex](y_{1}-y_{2})=m(x_{1}-x_{2})[/tex]
Our first point is (-3,2). Our second point is (0,-7). Therefore:
[tex]x_{1}=-3\\y_{1}=2\\x_{2}=0\\y_{2}=-7\\m=-3[/tex]
Plugging into the equation, we get
[tex](-7-2)=-3(-3-0)[/tex]

Johnnie runs 4.5 km everyday to stay in shape. It takes him 30 minutes to run his route. What is his average speed per hour?
Answers
Answer:
The average speed is 9 km per hour
Step-by-step explanation:
Average speed = total distance ÷ total time
Let us use this rule to solve the question
∵ Johnnie runs 4.5 km every day
∴ The total distance = 4.5 km
∵ It takes him 30 minutes to run his route
∴ Total time = 30 minutes
→ We need to change the time to hours to find the average speed in km/h
∵ 1 hour = 60 minutes
→ Divide the time by 60 to change it from minutes to hours
∴ Total time = 30/60 = 0.5 hour
∵ Average speed = distance ÷ time
∴ Average speed = 4.5 ÷ 0.5
∴ Average speed = 9 km/h
∴ The average speed is 9 km per hour

Walter and Brian each have a CD collection. The number of CDs in Walter's collection can be represented by x. The number of CDs in Brian's collection is 3 times the number in Walter's collection. The total number of CDs in both collections is 144. What is x, the number of CDs in Walter's collection?
Answers
Answer:
36CDs
Step-by-step explanation:
The number of CDs in Walter's collection can be represented by x. The number of CDs in Brian's collection is 3 times the number in Walter's collection.
Hence, Brian's collection = 3x
The total number of CDs in both collections is 144.
We have the Equation:
x + 3x = 144
4x = 144
x = 144/4
x = 36
Therefore, the number of CDs in Walter's collection is 36 CDs

We can divide all the given fractions to find there decimal equivalents.
7 ÷ 9 = 0.77...
7 ÷ 19 = 0.368421
7 ÷ 8 = 0.875
7 / 15 = 0.466...
Now, we see that these match up;
7.9 -> C or D (It's not specific in whether the 7 repeats so if it does on your end, please choose that option)
7/19 has no equivalent option.
