Answer:125
Step-by-step explanation:
So.. hmm check the picture below
now, to know where A and B are, that occurs when the parabolic equation equates the linear one
thus

now, running that on the quadratic formula, you end up with the values of 3.00402497440839842242 and 0.77175977895483027713
thus B rounded up is 3.004 and A rounded up is 0.7718
what's the "y" value for B?, well, you can use either the linear or quadratic equation for that, let's use the quadratic one
Answer:
21
Step-by-step explanation:
use PEMDAS
multiplication first
120-20×5+1 =
120-100+1=
20+1= 21
Answer:
31
Step-by-step explanation:
4*6=24
3^2=3*3=9
16+24-9=40-9=31
Answer:
12
Step-by-step explanation:
He went wrong when he did 16 + 3 first when he should have done 23 minus 16 which is 9. Then 9 plus 3 equals 12.
