Let x = Barbie's number
1/3 x -20 = 72
1/3 x = 92
x = 92*3=276
Y=mx+b
b represents your y-intercept
mx represents your slope
Answer:
Step-by-step explanation:
Elimination
A, they are both linear
linear equations are sometimes given by y=mx+b, equation A, if graphed, produces a hyperbola which is not linear so statement A is false
B they areboth non-linear
equationb is linear so this is false
C equation a is non-linear and equation b is linear
true
C is the answer
