Answer:
Elizabeth washes 99 windows each day.
Step-by-step explanation:
Given:
Total number of windows (N) = 2480
Marie washes windows = 4 times Elizabeth washes.
Elizabeth washes same number of windows for 5 days.
Let the number of windows washed by Elizabeth each day = 'x'.
Therefore, over the 5 days, the windows washed by Elizabeth =
Now, as per question:
Marie washes windows = 4 times Elizabeth washes.
So, number of windows washed by Marie =
Now, total number of windows = Windows washed by Marie + Windows washed by Elizabeth
So,
Therefore, Elizabeth washes 99 windows each day.
Answer:
Option C.
Step-by-step explanation:
If a line passes through two points and , then the equation of line is
The line passes through the points (1,0) and (0,-2). So, the equation of line is
It is a solid line and the shaded region lies below the line, so the sign of inequality must be "≤".
First inequality is .
The parabola intersect the x-axis at 0 and 3, so the equation of of parabola is
It is a solid curve and the shaded region lies above the curve, so the sign of inequality must be "≥".
Second inequality is .
Therefore, the correct option is C.
