Answer:c. 1 page
Step-by-step explanation:
Let x represent the number of hours that Jones takes to finish the pages
Let y represent the number of pages that Jones finishes in x hours.
Jones has already taken 1 page of notes on his own. Therefore, the equation becomes
y = 2x + 1
After 4 hours,
y = 2×4 + 1 = 8 + 1 = 9 pages.
This equation is in the slope intercept form where
m = Slope = 2 pages per hour of class
To get the y intercept, we will substitute x = 0 into the equation. It becomes
y = 2×0 + 1
y = 1
So the y intercept is 1 page
Answer:
the age of father is 42
Step-by-step explanation:
let the age of father be x then,
By the question,
or, 2÷7 of x = 12

or, x = 12 × (7÷ 2)
x = 42
