Hello :
let A and B two points in the first line calculate the slope : <span>: (YB - YA)/(XB -XA)
</span>let C and D two points in the second line calculate the slop (YC - YD)/(XC -XD)
you are slope
The total number of possible combinations from flipping a coin 10 times is 2^10 = 1024.
If general form means y=mx+b form then your answer would be B
A+c=100
3a+2c=275, from the first c=100-a making the 2nd equation become:
3a+2(100-a)=275 perform indicated multiplication on left side
3a+200-2a=275 combine like terms on left side
a+200=275, subtract 200 from both sides
a=75, and since c=100-a
c=100=75=25
So the answer is D. 25 children and 75 adults
Equation 1: a+c=100
Equation 2: 3a+2c=275
Answer:
B Right octbuse A acute D Right
