Answer:
Kendra should have multiplied the x-values by 75 to get the y-values
Step-by-step explanation:
Given
Table
X|| Y
1 || 75
2 || 150
3 || 225
4 || 300
5 || 375
Given that Kendra multiply x by 7.5 to get y
The relationship of x and y can be calculated as thus;
y = rx
Where y and x are the values at the y and x column respectively and r is the constant of proportionality
When y = 75, x = 1.
Plug in these values in the above formula
y = rx becomes
75 = r * 1
75 = r
r = 75
When y = 150, x = 2
150 = r * 2
Multiply both sides by ½
150 * ½ = r * 2 * ½
75 = r
r = 75
When y = 225, x = 3
225 = r * 3
Multiply both sides by ⅓
225 * ⅓ = r * 3 * ⅓
75 = r
r = 75
Notice that r remains 75 and the difference between y values is 75
If you apply these formula on when y = 300 or 375 and when x = 4 or 5, the constant of proportionality will remain The value of 75.
Hence, Kendra mistake is that; Kendra should have multiplied the x-values by 75 to get the y-values
Answer:
is there a picture of the graph?
Step-by-step explanation:
Let's say you have 10 and 15
You can divide both of them by 5
10/5=2
15/5=3
The greatest common factor is 5, because it is the highest number you can divide both numbers by, I hope this helps
Every millimeter is 1/10 of a centimeter, so 1 mm = 0.1 cm and 50 mm = 5 cm. This means that 25 mm can be re-written as 2.5 cm, and we can then find the difference by doing 25 - 2.5 = 22.5 cm. If you were looking for a different type of answer, you can also say that 25 mm is 10 times less than 25 cm.
I hope this helps!
Answer:
What? in this equation, x = 14. I'm not sure what the question is asking.
