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.

4 + 2/7x = 8 what does x equal
frozen [14]
Subtract 4 from both sides of the equation
you will end up with 2/7x=4
next multiply 7x by both sides
you will end up with 2=28x
next divide 28 from both sides
you will end up with x=1/14 in
fraction form. Hope this helps.

yanalaym [24]

Answer:

<u>A. Nicholas will have to pay less using plan A</u>

<u>B. He will pay US$ 4 less than plan B</u>

Step-by-step explanation:

Let's compare how much Nicholas will pay on internet service in Plan A and plan B, after using it 16 hours and 40 minutes.

Plan A

Up to 10 hours = US$ 6

Every subsequent 1/2 hour: $1

10 hours + 14 (1/2 hour)

<u>Nicholas will pay 6 + 14 * 1 = US$ 20</u>

Plan B

Up to 12 hours = US$ 4

Every subsequent 1/2 hour: $2

12 hours + 10 (1/2 hour)

<u>Nicholas will pay 4 + 2 * 10 = 24</u>
