Answer:
The independent variable is x
Step-by-step explanation:
In the equation y = m x + b
- m is the rate of change ⇒ constant
- b is the initial value ⇒ constant
x is the independent variable because it does not depend on any value
y is the dependent variable because it depends on the value of x
Let us solve the question
∵ 5x + 2y = 150
→ Put it in the form above by subtracting 5x from both sides
∵ 5x - 5x + 2y = 150 - 5x
∴ 2y = 150 - 5x
→ Divide each term by 2 to make the coefficient of y equal 1
∴ y = 75 - 2.5x
∴ y = -2.5x + 75
→ Compare is by the form above
∴ m = -2.5 and b = 75
∴ x is the independent variable (domain)
∴ y is the dependent variable (range)
Answer: B) 0.40 mi
Step-by-step explanation:
Using the Pythagorean Theorem.
A squared + B squared = C squared.
A = leg B = leg C = hypotenuse
A = 0.3 B = ? C = 0.7
0.3 squared x ? squared = 0.7 squared
