Answer:
15:20=3:4
Step-by-step explanation:
Which equation best models the relationship between x and y?
y = −5x + 25
y = −25x + 125
y = −25x + 175
y = −5x + 125
Equation best models the relationship between x and y is :y = −25x + 175
The correct option is (C).
Equation, statement of equality between two expressionsconsisting of variables and/or numbers.
Given that :
John reads an equalnumber of pages of a book every week.
If the number of pages of the book left to read, y, after xweeks.
x-axis y-axis
0 0
1 25
2 50
3 75
4 100
5 125
6 150
7 175
Then the representation of equation is :
y+25x=175 (total pages is 175).
Hence, y=-25x+175
