7 hours X 60 minutes = 420 minutes
420 minutes + 20 minutes = 440 minutes
Answer:
x =0 and x = 4
Step-by-step explanation:
It is a quadratic function and hence will have two roots. It cuts graph at 2 points( x - axis ). Hence has two roots.
Answer:
Option D) is correct
That is x=2 , y=-5
Step-by-step explanation:
Given that the 
To find their determinants

=-8+48
=40
Therefore 

=-76+156
=80
Therefore 

=104-304
=-200
Therefore 
To find the values of x and y:

and 
x=2 and y=-5
Option D) is correct
That is x=2 , y=-5
.24 = 24/100 = 12/50 = 6/25
Start by realizing that n*p = (-5)(-2) = 10.
The reason is because an even number of minus signs will give a plus. Since 2 minus signs are multiplied together, the answer is > 0. or plus.
10/np = 10/10 = 1 <<<< Answer
