Answer:

x = 5

Step-by-step explanation:

$3(3x + 3) - 5x - 4= 25\\\\9x+9-5x-4=25\\\\9x-5x+9-4=25\\\\4x+5=25\\\\4x+5-5=25-5\\\\4x=20\\\\\frac{4x=20}{4}\\\\\boxed{x=5}$

Hope this helps.

______________________________

3(3x + 3) -5x - 4 = 25

9x + 9 - 5x - 4 = 25

9x + 9 - 5x = 25 + 4

9x + 9 - 5x = 29

9x - 5x = 29 - 9

4x = 20

x = 20/4

x = 5

Answer:

$y=\frac{6}{5}x-24$

Step-by-step explanation:

$Since\ the\ yellow\ points\ are\ \left(20,0\right)and\ \left(70,60\right)$
$so,\ set\ the\ equation\ of\ this\ is\ y=mx+b$
$\rightarrow0=m\times20+b$
$60=m\times70+b$

$get\ m=\frac{6}{5},b=-24$

$so,\ the\ slope-intercept\ form\ of\ it\ is$
$y=\frac{6}{5}x-24$
$\left\{Substitution\ method\right\}$

I hope this helps you

Which graph indicates decreasing speed? A. Graph c B Graph A c graph F d graph

Bas_tet [7]

I think that it would be option A. Graph C. It shows the line going down from the y-axis to the x-axis, so it would be graph C.
