The value of m must be 4 and the value of b must NOT be -3.
No matter what numbers they involve, two equations with the SAME slope (m) and a DIFFERENT y-intercept (b) have no solution. This is because they form parallel lines, never crossing and therefore never giving a solution.
Answer:
<em>1:45 P.M</em>
Step-by-step explanation:
time = 60 + 45 + 60 + 40 + 60 + 5 = 180 + 90 = 270
270/60 = 4 hrs and 30 mins
6:15 - 4 hrs = 2:15
2:15 - 30 mins = 1:45 pm
21a to the second and b to the 5
Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A

-----> equation B
Substitute equation B in equation A
Find the value of x


therefore
<u>the answer is</u>
the number of multiple choice question are 
the number of free response question are
