Answer:
78
Step-by-step explanation:
(-5)•(-5) + 3•21= 25+ 63= 78
Answer:
As the wheel makes this 270 degree counterclockwise rotation about the origin, the y-coordinate of the first car decreases from 80 to 0 and then further from 0 to -80, and finally increases to 0.
The x-coordinate decreases from 0 to -80 and then increases to 0; from there it increases further to 80.
Thus, the coordinates of the first car, after this 270-degree rotation, are (80, 0).
Answer:
y=5x-2
Step-by-step explanation:
Answer:
For four days it would be $19.8. For seven days it would be $24.9
Step-by-step explanation:
4 days:
$4.70 x 4 + 1= 19.8
7 days:
$4.70 x 7 = $24.9
I took away 1 from the 4 day equation because the question said you get a dollar off if you return the dvd before 5 days.
Hope this helps!
