How many solutions does the system have? y = -2x-4 \\\\ y = 3x+3

Mathematics
1 answer:
lakkis [162]3 years ago
3 0

Answer:

The system has one solution.

Step-by-step explanation:

We have two equations:

y = -2x - 4

y = 3x + 3

Equalling them:

y = y

-2x - 4 = 3x + 3

5x = -7

x = -\frac{7}{5}

And

y = 3x + 3 = 3(-\frac{7}{5}) + 3 = \frac{-21}{5} + 3 = \frac{-21}{5} + \frac{15}{5} = -\frac{6}{5}

Replacing in the other equation we should get the same result.

y = -2x - 4 = -2(-\frac{7}{5}) - 4 = \frac{14}[5} - 4 = \frac{14}{4} - \frac{20}{5} = -\frac{6}{5}

So the system has one solution.

let's solve for " w "

  • vw {}^{2}  + y = x

  • vw {}^{2}  = x - y

  • {w}^{2}  =  \dfrac{x - y}{v}

  • w =  \sqrt{ \dfrac{x - y}{v} }

Which inequality describes this graph?
ZanzabumX [31]

The inequality that describes this graph of the number line is x ≥ 4

<h3>How to determine the inequality that describes this graph?</h3>

From the question, we have the following properties:

  • The graph is a number line
  • The number line extends at both ends
  • The number line starts from less than -5 and ends at greater than 5
  • There is a heavy arrow that extends from a circle over positive 4 to the right.

The property 3 above implies that the domain of the number line is the set of all real numbers.

The property 4 above implies that the inequality of the number line is a greater than or equal to inequality, and the value starts from 4

This is represented by the following inequality

x ≥ 4

Hence, the inequality that describes this graph of the number line is x ≥ 4
