Answer: See explanation. Hope this helps, please consider making me Brainliest.
Step-by-step explanation:
To find the rate of change, subtract then divide. This is especially a good strategy when you have the x and y values when x = 0:
604 - 460 = 144
144 divided by 18 =
8
Therefore, the rate of change is 8. We can even go further to create an equation for this:
y intercept = 460 (because 0 multiplied by the rate of change would be 0).
slope = 8
Slope-intercept form: y = mx + b --> y = 8x + 460

Answer:
-2(x+2)(4x-35)
Step-by-step explanation:
Factor out the 2 and by grouping.
The teachers plan will raise money is 1.8 times the static graders plan.The teachers plan to raise a dollar is 5/6 times the static graders plan to raise a dollar.More dollars will be raised by the teachers plan compared to the static graders plan.
Step-by-step explanation:
In the question,
Let what the static graders plan to rise to be $x.
Let what the teachers plan to rise to be $ y
You understand that ;
y =210 +x ----------------(this is 210 dollars more than the static graders raise)
y=x+4/5 x -------------------(but only 4/5 as much as the static graders)
Solving the equations to get x and y
210+x=x+4/5x
5(210+x)=5*x+4x
1050+5x=5x+4x
1050=5x+4x-5x
1050=4x
1050/4=4x/4
x=$262.50
y=210+262.50=$472.50
Additionally, for every $60 raised in teachers plan, the static graders raise $50
This means in teachers plan 1$ raised equals 5/6$ raised in static plan
y=5/6x
