PLZ help<br> What system of linear inequalities is shown in the graph?
GarryVolchara [31]

In order find the Inequalities, First we need to Find the Equations of Both the Lines.

<u>Equation of First line :</u>

It is passing through the Points (0 , 2) and (4 , 0)

⇒ Slope = \frac{2 - 0}{0 - 4} = \frac{-2}{4} = \frac{-1}{2}

⇒ Equation of the First Line : y - 2 = \frac{-1}{2}(x)

⇒ Equation of the First Line : x + 2y = 4

<u>Equation of Second Line :</u>

It is passing through the Points (1.5 , 0) and (0 , -3)

⇒ Slope = \frac{0 + 3}{1.5 - 0} = \frac{3}{1.5} = 2

⇒ Equation of the Second Line : y + 3 = 2x

⇒ Equation of the Second Line : 2x - y = 3

As the Shaded Area of the First Line is away from the Origin :

⇒ x + 2y ≥ 4

As the Shaded Area of the Second Line is towards the Origin and it is a Dotted line :

⇒ 2x - y < 3

So, the System of Linear Inequalities are :

⇒ x + 2y ≥ 4

⇒ 2x - y < 3

Consider the quadratic function y = 0.3 (x-4)2 - 2.5 <br> Determine the axis of symmetry, x =
fomenos

Answer:

x=4

Step-by-step explanation:

We have the quadratic function:

\displaystyle y=0.3(x-4)^2-2.5

And we want to determine its axis of symmetry.

Notice that this is in vertex form:

y=a(x-h)^2+k

Where (<em>h, k</em>) is the vertex of the parabola.

From our function, we can see that <em>h</em> = 4 and <em>k</em> = -2.5. Hence, our vertex is the point (4, -2.5).

The axis of symmetry is equivalent to the <em>x-</em>coordinate of the vertex.

The <em>x-</em>coordinate of the vertex is 4.

Therefore, the axis of symmetry is <em>x</em> = 4.

What is the solution to the system of equations?<br><br> y = 1/3x – 10<br><br> 2x + y = 4
Mekhanik [1.2K]
Y = 1/3 x - 10 . . . (1)
2x + y = 4 . . . . . (2)

Putting (1) into (2) gives
2x + 1/3 x - 10 = 4
7/3 x = 4 + 10 = 14
x = (3 x 14)/7 = 3 x 2 = 6
x = 6

From (1), y = 1/3 (6) - 10 = 2 - 10 = -8
y = -8
