Answer:
43b. (-1, 2)
43a. (1, -3)
36b. Yes: (0,9)
Step-by-step explanation:
<u>43b</u>. x+y=1
-x+y=3
----------------------
2y=4 > y=2
2+x=1 > x=-1
check:
2(-1)+2=0
0=0
<u>43a</u>. can you figure this one out by yourself and then check it? If you can't I will show my work. The answer is above. :)
<u>36b</u>. y-(0)^2=9
y=9
x=24.621
tan(72)=x/8
tan(72)×8=x
The womans age is 25
mothers age is 50
add those up and you get 75
[f(3) - f(0)]/(3-0)
[f(3) - f(0)]/3
