Rowan reads at a constant rate of 1.5 pages per minute and has already
1 answer:
Using linear functions , it is found that Rowan and Kennedy will have read the same number of pages in 10 minutes.
What is a linear function?
A linear function is modeled by:
In which:
a is the slope , which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept , which is the value of y when x = 0.
For Rowan , we have that:
He has already read 20 pages, hence the y-intercept is . He reads 1.5 pages per minute, hence the slope is Then:
For Kennedy , we have that:
He has already read 25 pages, hence the y-intercept is . He reads 1 page per minute, hence the slope is Then:
They will have read the same number of pages after x minutes , for which:
Then:

<span>I can solve for x and y A) 2x - 4y = 12
A) 2x = 4y + 12 A) x = 2y + 6 Substituting into B B) 3* (2y +6) - 5y = 20
B) 6y + 18 -5y = 20 B) y = 2 B) x = 10 </span>
This is an imaginary number = sqrt105 * i = 10i ro nearest integer
I would start like this: which year was the seventh AMC 8?? the first was in 1985 The second: 1986 3: 1987 4: 1988 5: 1989 6: 1990 7: 1991 so seventh AMC 8 took place in 1991. she was then 12, so we can subtract this age from 1991: 1991-12=1979 so she was born in 1979!
Answer:
580
Step-by-step explanation:
You should plug the x and y values into the original equations to get your b value. You should get a b value of 7. Your new equation should be y=2x+7
