You can use greatest common factor(gcf)
list the factors of 18 and 30.
18- 1, 2, 3, 6, 9, 18
30- 1, 2, 3, 5, 6, 10, 15, 30
now the factor that is greatest is 6.
this mean you can use the largest square tile of 6in by 6in without overlap or cutting.
<em><u>Complete Question:</u></em>
You can model the population of a certain city between 1955-2000 by the radical function
P(x) = 55,000 sqrt x-1945
Using this model, in which year was the population of that city 275,000?
<em><u>Answer:</u></em>
In 1970 population of that city is 275,000
<em><u>Solution:</u></em>
Given that,
<em><u>You can model the population of a certain city between 1955-2000 by the radical function
:</u></em>
To find: year in which was the population of that city 275,000
Therefore,
x = ?
P(x) = 275000
Thus we get,
Thus, in 1970 population of that city is 275,000
One scale factor equation is y=cx
y is the new factor (in this case, 60 or 75)
c is the scale factor (in this case, unknown)
x is the old factor (in this case, 24 or 30)
so: plug in the values
60=c(24) divide both sides by 24
c=2.5
you can check again with the other numbers
75=c(30) divide both sides by 30.
c= 2.5
your scale factor is 2.5
Answer: y = 8x -3
Step-by-step explanation:
we know the slope already which is 8.
so the equation is: y = 8x + b
subsutite the x and y to get the value of b
21 = 8(3) + b
21 = 24 + b
b = -3
So the equation is: y = 8x -3
