Answer:

2

Step-by-step explanation:

Take any 2 points on the graph,

(80, 90) & (40, 10)

Use the slope formula:

\frac{y2-y1}{x2-x1}

= (10-90)/(40-80)

= (-80)/(-40)

= 2

Hence, the slope is 2.

Last month, the soccer team held a bake sale to raise money for new uniforms. They did not raise enough money, so they organized
VLD [36.1K]

Answer:

215; 8; 367

Step-by-step explanation:

231=7x+c

319=18x+c

c=The amount from bake sale (since it doesn't changes throughout the car wash)

x=$ earned per car

 319=18x+c

-(231=7x+c)

Use elimination and subtract the values to get rid of a variable.

(319-231, 18x-7x, c-c)

88=11x

x=88/11

x=8

∴ The soccer team earns $8 per car.

231=7*8+c

231=56+c

c=231-56

c=175

∴ The soccer team made $175 from the bake sale.

The ans. is per blank from top ro bottom

1. c+5x=175+5*8

  175+40 = 215

2. 255=c+?x

  255=175+?*8

  255-175=?*8

  80=?*8

  ?=80/8

  The soccer team washed 8 cars n earned $255

3. c+24x=175+24*8

   175+192= 367

  The soccer team earned $367 after 24 cars.
