Do you want us to do all seven? I don't think so.
17. s for Sonia, m for Sam, n for Nigel
s = 13.2 + 1.4 m
n = -10 + 2.5 m
n = 12 + s
First and third,
n = 12 + (13.2 + 1.4 m)
Second and that one,
-10 + 2.5m = 25.2 + 1.4m
1.1m = 35.2
m = 35.2/1.1
m = 32
Answer: 32 kg

f - # of $500 tickets, t - $300 tickets, w - $200 tickets
t = 2f
w = -60 + t
500f + 300t + 200w = 48000
f = t/2
500(t/2) + 300t + 200(-60 + t) = 48000
750t = 60000
t = 80
w = -60 + t = 20
Answer: 20
19.
c + b = 171
c/9 = b/9 -5
c = b - 45
Adding,
2c + b = b + 126
c = 63
Answer: 63
Three's my limit.
Given data:
The first set of equations are x+y=4, and x=6.
The second set of equations are 3x-y=12 and y=-6.
The point of intersection of first set of te equations is,
6+y=4
y=-2
The first point is (6, -2).
The point of intersection of second set of te equations is,
3x-(-6)=12
3x+6=12
3x=6
x=2
The second point is (2, -6).
The equation of the line passing through (6, -2) and (2, -6) is,
Thus, the required equation of the line is y=x-8.
Answer:
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.
