1.
Rate of change: 1:5
Equation: x · 5 = y
Is this relationship proportional? Yes
How do you know? I know, because the table never doesn't follow the equation.
2.
Rate of change: 1:1
Equation: x · 1 = y
Is this relationship proportional? Yes
How do you know? I know, because the table never doesn't follow the equation.
Cost=$200
sales tax rate, r= 8%
tax=cost*r=$200*0.08=$16
total cost = cost+tax=$200+$16=$216
2.) line passes through points (-1, -4) and (0, -1)
slope = (y2 - y1)/(x2 - x1) = (-1 - (-4))/(0 - (-1)) = (-1 + 4)/(0 + 1) = 3/1 = 3
4.) line passes through points (0, -3) and (2, 0)
slope = (0 - (-3))/(2 - 0) = (0 + 3)/2 = 3/2
83,000,023,007 is the answer.
Answer:
A. -13
Step-by-step explanation:
y - (-5) is the same as y + 5
x - 8 = y + 5; you then subtract 5 from both sides
x - 13 = y
