A system of equations is graphed on the coordinate plane.

valkas [14]

Answer:

Inconsistent

Step-by-step explanation:

we know that

If a system of two linear equations have at least one solution, it is said to be consistent .

If a consistent system has exactly one solution, it is independent .

If a consistent system has an infinite number of solutions, it is dependent .

If a system of two linear equations no have solution, it is said to be inconsistent.

Remember that

When solving a system of linear equations by graphing, the solution of the system is the intersection point both graphs

In this problem we have

$y=-2x-3$ ----> equation A

$y=-2x+2$ ----> equation B

Their slopes are equal (m=-2) and their y-intercept are different

so

we have two different parallel lines

The lines not intersect

therefore

The system has no solution, because is inconsistent

A particle moves along the curve below. y = √ 8 + x 3 As it reaches the point ( 1 , 3 ) , the y -coordinate is increasing at a r

REY [17]

Answer:

The x-coordinate is changing at 10 cm/s

Step-by-step explanation:

Rate of Change

Suppose two variables x and y are related by a given function y=f(x). If they both change with respect to a third variable (time, for instance), the rate of change of them is computed as the derivative using the chain rule:

$\displaystyle \frac{dy}{dt}=\frac{dy}{dx}\cdot \frac{dx}{dt}$

We have

$y=\sqrt{8+x^3}$

Or, equivalently

$y^2=8+x^3$

We need to know the rate of change of x respect to t. We'll use implicit differentiation:

$\displaystyle 2y\cdot \frac{dy}{dt}=3x^2\cdot \frac{dx}{dt}$

Solving for dx/dt

$\displaystyle \frac{dx}{dt}=\frac{2y\cdot \frac{dy}{dt}}{3x^2}$

Plugging in the values x=1, y=3, dy/dt=5

$\displaystyle \frac{dx}{dt}=\frac{2(3)\cdot 5}{3\cdot 1^2}=10$

The x-coordinate is changing at 10 cm/s

Answer:

Which graph represents the function f(x) = (x – 3)2?

On a coordinate plane, a parabola opens up. It goes through (negative 6, 8), has a vertex at (negative 3, 0), and goes through (negative 0, 8).

On a coordinate plane, a parabola opens up. It goes through (negative 4, 7), has a vertex at (0, negative 9), and goes through (4, 7).

On a coordinate plane, a parabola opens up. It goes through (1, 4), has a vertex at (3, 0), and goes through (5, 4).

On a coordinate plane, a parabola opens up. It goes through (negative 2, 7), has a vertex at (0, 3), and goes through (2, 7).

Answer:

The x coordinate would be 4.

Step-by-step explanation:

In order to find this, we'll make the y terms cancel. To do this, we need to multiply the whole second term by -1 and then add them together.

3x + 5y = 10

-x - 5y = -2

-----------------

2x = 8

Now that we have this, we can divide to get the answer.

2x = 8

x = 4
