Answer:
y = 7x
y = $133
Step-by-step explanation:
x = independent variable
y = dependent variable
y = 7x
Where,
y = total amount saved
x = number of weeks
7 = constant
When x = 19
y = 7x
y = 7 * 19
y = 133
y = $133
(3x - 2y) / (z + 4)........x = 1, y = -2, z = 3
now we start subbing
((3(1) - 2(-2)) / (3 + 4).....simplify
(3 + 4) / (3 + 4) =
7/7 =
