Answer:
2628.48 cubic inches
Step-by-step explanation:
The inflatable raft has 4500 cubic inches of air inside it when fully inflated.
The inflatable raft loses air at a rate of a decrease 6.5% each day.
Now, we have to calculate the volume of air that will be left in the raft after 8 days.
Therefore, the volume of air left in the raft after 8 days will be cubic inches. (Answer)
Answer:
The slope of the line given by the linear equation is -2
The slope of the line shown in the graph is -1
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
- m is the slope
- b is the y-intercept
The rule of the slope of a line is m = , where
- (x1, y1) and (x2, y2) are two points lie on the line
Let us use these rules to answer the question
∵ The linear equation is y = -2x + 7
→ By comparing it with the form of the linear equation above
∴ m = -2
∵ m is the slope of the line represented by the given equation
∴ The slope of the line given by the linear equation is -2
From the given figure
∵ The line passes through points (6, 0) and (0, 6)
∴ x1 = 6 and y1 = 0
∴ x2 = 0 and y2 = 6
→ Substitute them in the rule of the slope above to find it
∵ m =
∴ m = -1
∵ m is the slope of the line shown in the graph
∴ The slope of the line shown in the graph is -1
