What is the range of the function represented by the graph?<br> I need help ASAP
kumpel [21]

Step-by-step explanation:

The range of a function is basically the y-value of the lowest point in the function and the y-value of the highest point in the function.

In the graph shown, the lowest point is (0,1) and the highest is (3, 4). Their y-values are 1 and 4 respectively.

The points are not connected in a straight line. Instead, they are separate points with a difference of 1 in their y-values.

So the answer is {1, 2, 3, 4}

Solve the system of equations.<br> ​ <br> −5x−3y−9=0<br> 4x−18y−54=0<br> y=? x=?<br> ​
Darina [25.2K]

Answer:

Step-by-step explanation:

Eq. 1 )   −5x−3y−9=0

Eq. 2)   4x−18y−54=0

there are two routes to solve this,   Substitution or  elimination,  I'll go for the 2nd one because I can see that the y values are a multiple of each other :)

    6 *( −5x−3y−9=0 )

Eq. 3) -30x -18y =54

subtract Eq. 2 from Eq. 3  :)

-30x -18y =54

<u>-( 4x−18y=54)</u>

-34x = 0

so according to the equations then x =0 but,  that's not really a full answer, so now we should go back and try the other method, substitution,

then:

-5x = 9 +3y

x = - 9/5 + (-3/5)y

now plug that into Eq. 2

4( - 9/5 + (-3/5)y ) - 18y = 54

-36/5 + (-12/5)y -18y = 54

(-12/5)y - (90/5)y = 54+36/5

-(102/5)*y =270/5+36/5

-(102/5)y = 306/5

y = (-5/102)*(306/5)

y = -306/102

y = -3

then plug in for either equation

-5x-3( -3) = 9

-5x + 9 = 9

-5x = 0

x = 0

now we have the full answer

check it by plugging in both x and y into the 2nd equation

4(0) - 18(-3) = 54

54= 54

this seems good
