# How do i find the anwser to this question

If you're solving for y it has to be this way
-7y=-3x+9
Y=3/7x -9/7
If you're solving for x
3x=7y+9
X=3/7y+3/1
Graph. red• 25+0.5d (music city)
blue•. 1.5d

Music city
C=25+0.5d
C-cost

Tune Dune
C=1.5d

Tune Dune is cheaper until the 25 song downloaded, the they are equal. After that, Music city is cheaper.

Could you give more info so I can try and sole it?

Step-by-step explanation:

x-intercept= (2,0)

Because graph crosses x-axis at x=2

y-intercept= (0,4)

Because graph crosses y-axis at y=4

Domain= All real numbers.

Because graph covers all x-values along x-axis when checking from left side to right side.

Range = All real numbers.

Because graph covers all y-values along y-axis when checking from bottom side to up side.

Minimum = NO

Maximum = NO

Increasing Interval = NO

Because graph goes all the time downward.

Decreasing Interval = (-infinity, infinity)

Because graph goes all the time downward when looking from -infinity to infinity.

Same way we can solve other problems.

x-intercept= (-1,0), (2,0)

y-intercept= (0,-2)

Domain= All real numbers.

Range = [-2.25, infinity)

Minimum = -2.25

Maximum = NO

Increasing Interval = (0.5, infinity)

Decreasing Interval = (-infinity, 0.5)

x-intercept= (-2,0)

y-intercept= (0,-6)

Domain= All real numbers.

Range = (-infinity, 2)

Minimum = NO

Maximum = NO

Increasing Interval = NO

Decreasing Interval = (-infinity, infinity)

x-intercept= (-4,0), (2,0)

y-intercept= (0,-2)

Domain= All real numbers.

Range = (-3,infinity)

Minimum = -3

Maximum = NO

Increasing Interval = (-1, infinity)

Decreasing Interval = (-infinity, -1)

4 = (2+2x)-x
4 = (2+2(2))-2
4 = (2+4)-2
4 = 6-2
4 = 4
Which makes x=2
-6 = M you’d have to subtract one on both sides and then add that -1 to the -5
