Answer:3
I’m sorry if it’s wrong
Step-by-step explanation:
3^15/3^3 = 3^12 or 531441
If the school spent $1,137.50 and wants to make a $1500 profit, then they need to make $2637.50 to earn back what they spent and make a profit. So, if you divide $2637.50 by 350, the number of books they purchased, you get the amount each book would have to cost to make this much money. The lowest price they could sell them for is $7.54.
The equation of the line is y =
x +
Step-by-step explanation:
The form of the linear equation is y = mx + b, where
- m is the slope of the line,
- b is the y-intercept, to find b substitute x and y in the equation by the coordinates of any point on the line
∵ A line passes through points (
, 5) and (
, 4)
∴
=
and
=
∴
= 5 and
= 4
- Substitute them in the rule of the slope to find m
∵
∴
- Substitute it in the form of the equation
∴ y =
x + b
- To find b substitute x and y in the equation by the coordinates
of any point on the line
∵ Point (
, 5) lies on the line
∴ x =
and y = 5
∴ 5 =
(
) + b
∴ 5 =
+ b
- Subtract
from both sides
∴
= b
∴ y =
x +
The equation of the line is y =
x +
