\dfrac{x-3}5 = \dfrac{x+5}3 \\\\\implies 3(x-3)  = 5(x+5)\\\\\implies 3x - 9 = 5x +25\\\\\implies 5x -3x +25 +9 =0\\\\\implies 2x +34 =0\\\\\implies 2x = -34 \\\\\implies x = -\dfrac{34}2 =-17

\sf \longmapsto \:  \dfrac{x - 3}{5}  =  \dfrac{ x  + 5}{3}

\sf \longmapsto \: 3(x - 3) = 5(x + 5)

\sf \longmapsto \: 3x - 9 = 5x + 25

\sf \longmapsto3x - 5x = 25 + 9

\sf \longmapsto - 2x = 34

\sf \longmapsto \: x =  \dfrac{34}{ - 2}

\sf \longmapsto \: x =- \cancel  \dfrac{34}{ 2}

\sf \longmapsto \: x = -  17

\boxed{\Rightarrow\:  x = - 17}

Eight times the difference of a number and seventeen is thirty
charle [14.2K]

OK.  Great.  Thanks for sharing.  Do you have a question to ask ?

My hunch is that you want to know what the "number" is.
Here's how to set it up and solve it:

"a number"  . . . . . . . . . . . . . . .    Q

"The difference of 
a number and 17"  . . . . . . . . . .   Q - 17

"eight times the difference"  . . .  8 (Q - 17)

"is thirty"  . . . . . . . . . . . . . . . . . . 8 (Q - 17)  =  30  


Eliminate parentheses on the left side:

                                                    8Q - 136  =  30

Add  136  to each side:               8Q           =  166

Divide each side by  8 :                 Q           =   20.75

Graph the linear inequality x<-3 on a coordinate plane
jeyben [28]

Answer:

The graph is attached.

The graph of x < -3 should be a dotted line x = -3 on the cartesian plane.

The area below x = -3 should be shaded to show that  x < -3.

Graph the following points on the graphing calculator:
Nimfa-mama [501]
Brainly says you need the following points

- The pattern is min-zero-max-zero-min, which is the pattern for a cosine function of the form y = acos(x) + k, but is reflected over the x-axis (so a < 0).
- The amplitude is |a|, so a = –1 and |a| = 1.
- The midline is exactly between the max and the min, y = (6 + 8)/2 = 7, so k = 7.
- The equation is y = –cos(x) + 7.
