The set must have a constant additive rate of change.

Answer: Option A.

<u>Explanation:</u>

A function has an additive rate of change if there is a consistent distinction between any two successive information and yield esteems. From the primary table we can watch a consistent distinction of - 6 among the y-values and a steady contrast of 2 among the x-values.

A linear function has a consistent additive rate of change, while a nonlinear capacity doesn't. For a table of qualities to be direct, the needy variable must have a steady pace of progress as the autonomous variable increments by 1.

A system of equations is graphed on the coordinate plane.
8_murik_8 [283]

Answer:

  • The solution is (x, y) = (-2, 0)
  • A graph is attached

Step-by-step explanation:

The graph shows the solution. The first equation has a y-intercept of -4 and a slope of -2, so will go through the point (-2, 0).

The second equation has a y-intercept of +4 and a slope of 2, so will go through the point (-2, 0).

Both equations have the same x-intercept, so that x-intercept is the solution to the system of equations.

Definition: An outcome in a probability experiment.
snow_tiger [21]

Answer: possible result of an experiment

Step-by-step explanation: in probability theory, An outcome is a possible result of an experiment. Each possible outcomes of a particular experiment is unique, and different outcomes are mutually exclusive (Only one outcome Will occur on each trial of the experiment). All of the possible outcomes of an experiment formed elements of a sample space.

3x+1/5y=7 solve for y
Vladimir79 [104]
Hello!

First, let's write the problem.
3x+\frac{1}{5}y=7
Subtract 3x from both sides.
3x+\frac{1}{5}y-3x=7-3x
\frac{1}{5}y=7-3x
The opposite of division is multiplication, so we are going to multiply in order to undo the fraction.
5\cdot \frac{1}{5}y=5\cdot \:7-5\cdot \:3x

Our final answer would be, 
y=35-15x

Thanks!

A helium-filled blimp stays aloft since helium is less dense than regular air, so helium will rise above regular
worty [1.4K]

Answer:

The blimp can carry 70 passengers

Step-by-step explanation:

Lets use the ratio method to solve this problem

∵ 1 cubic meter of helium  can lift about 1.1 kg

∵ A blimp can carry as much as 2 x 10^{5} m³ of helium

By using the ratio method

→  m³         :  kg

→  1            :  1.1

→  2 x 10^{5}   :  x

By using cross multiplication

∴ x × 1 = 1.1 × 2 x 10^{5}

∴ x = 2.2 x 10^{5}

∵ x represents the mass that can carried by the helium

∴  2 x 10^{5} m³ of helium can lift 2.2 x 10^{5} kg

∵ The mass of the blimp is 2.13 x 10^{5} kg

- Subtract the mass of the blimp from the mass that the given

    amount of helium can lift to find the mass of the passengers

∴ The mass of the passengers = 2.2 x 10^{5} - 2.13 x 10^{5}

- Subtract 2.13 from 2.2 ⇒ 2.2 - 2.13 = 0.07

∴ The mass of the passengers = 0.07 x 10^{5}

∵ The average mass of a person with luggage is 10² kg

- Divide the mass of the passengers by the mass of the person

   to find the number of the passengers

∴ The number of passengers = 0.07 x 10^{5} ÷ 10²

- Subtract the exponents of 10 to find the answer

∵ 10^{5} ÷ 10² = 10^{5-2} = 10³

∴ The number of passengers = 0.07 x 10³

∴ The number of passengers = 0.07 × 1000

∴ The number of passengers = 70

The blimp can carry 70 passengers
