Answer:
$14.88
Step-by-step explanation:
Ria earns 1.2 times more than Peter does
Peter earns $12.40
To solve, you have to multiply the amount peter has by 1.2
12.40(1.2) = 14.88
Therefore, Ria earns $14.88
x is the independent variable.
y is the dependent variable.
-3 is the rate of change (slope).
-7 is the initial value.
Step-by-step explanation:
The form of the linear relation is y = m x + b, where
- m is the rate of change (slope)
- b is the initial value(value of y at x = 0)
- x is the independent variable
- y is the dependent variable
∵ The equation of the line is y = -3 x - 7
- Compare it with the form above
∴ m = -3
∵ m is the rate of change
∴ The rate of change is -3
∴ b = -7
∵ b is the initial value
∴ The initial value is -7
∵ y depends on x
∴ x is the independent variable
∴ y is the dependent variable
x is the independent variable.
y is the dependent variable.
-3 is the rate of change (slope)
-7 is the initial value.

Answer:
$5,250
Step-by-step explanation:
2/7x - [4/5(2/7x)] = 300
2/7x - 8/35x = 300
10/35x = 8/35x = 300
2/35x = 300
2x = 10500
x = 5250
