1/2
Step-by-step explanation:
Answer: b is about 13.8 or choice A.
See picture reply.
The tip is $15.73. I get that by multiplying 78.63 and .20. then you add the tip to the bill and get $94.36. you then find the discount by multiplying 94.36 and .15. the discount is 14.15. then subtract 14.15 from 94.36 to get your total.
the answer is $80.21
Y+5=m(x-3), or y=mx-3m-5, satisfies Equation 1. But Equation 1 and Equation 2 are satisfied when y-7=n(x+1).
(-1,7) is graphically represented by the intersection of 2 lines. So Equation 1 must pass through (-1,7) and (3,-5). The slope is (-5-7)/(3-(-1))=-12/4=-3=m, so y=-3x+4.
Equation 2 is y=x+8 when n=1 (arbitrary choice). Note that m is not equal to n.
A typical example of the required system is Eqn 1: y=-3x+4 and Eqn 2: y=x+8.
The anwser is 930 because 900 plus 30 is 930
