All the points on those lines are a part of the domains and the ranges. The domain points are the "x" values of the points on those lines. The range points are the "y" values of the points on those lines.
The first square in the top left hand corner:
Domain: -3, -1, 0, 1, 2
Range: 0, -1, 1, 0, -1
X = nr. hrs working for a farmer;
y = nr. hrs. babysitting;
x + y <= 25;
10x + 5y >= 150
a) Solve the system => one of the solution is x =5; y = 20(babysitting)
b) 10 + 12 =22 <= 25; 10*10 + 5*12 = 160 >=150.
I think the answer is between-5 to 10
The probability of a head or tail upon flipping is 50-50. THe asnwers are as followsL
a. {HHH, HHT, HTT, TTT, TTH, THH, HTH, THT}b and c. p = 3C3 * 0.5^3 = 0.125d. from a, p = 3/8 = 0.375e. from a, p = 3/8 = 0.375f. 0.875
Y = t x 15 + 55
15 equals the rate of change or the constant of proportionality and 55 is equal to the y-intercept, or the number of stamps you originally had
