C(x) = 300.
Our question becomes simple: 300 = x^2-40x+610
x^2-40x+610-300 = 0
x^2-40x+310 = 0
Now find the value for x with either the quadratic formula or by factorization.
Let me know how it goes. Giving the full answer won’t help you improve
Step-by-step explanation:
5*(4x+8)=6*(2x+3)
20x+40=12x+18
20x _12x= 18_40
8x = _22
x=_22/8
x= _11/4
Answer:

Step-by-step explanation:
Slope-intercept form means

where m is given its the slope which is
and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,




now we know the value of slope which is given
and we found the value of which is 1 so we put these values into our original slope-intercept form equation

C- in the table every ratio y/x is equal so the relationship is proportional
