get a common denominator which is 12
2 1/3 = 2 4 /12
5 3/4 = 5 9 /12
2 4/12 + 5 9/12 = 7 13/12
7 + 1 1/12
8 1/12
Step-by-step explanation:
the first question
x²+x+5
when x is -4
(-4)²+(-4)+5
16-4+5
12+5
17
hope this was helpful
=> 4x = 16 - 8
=>4x= 8
=> x= 2
in short the answer is 2
Slope is mx is that makes sense
