28,000 + 3,000x = 30,000 + 2,800x
3,000x - 2,800x = 30,000 - 28,000
200x = 2,000
x = 2,000/200
x = 10....after 10 yrs, company A and company B will be the same
5x^2+6=f(x)
and your graph plug that equation into an graph creator and it will automaticlly make your graph
i would subtract 7 and divide by 4;
4x + 7 = 15
4x = 8
x = 2
-10x + 20 should be the right answer.
Answer:
(s-6)/r
option D
Step-by-step explanation:
The slope-intercept form a line is y=mx+b where m is the slope and b is the y-intercept.
Compare y=mx+b and y=cx+6, we see that m=c and c is the slope.
Now we are also given that (r,s) is on our line which means s=c(r)+6.
We need to solve this for c to put c in terms of r and s as desired.
s=cr+6
Subtract 6 on both sides:
s-6=cr
Divide both sides by r:
(s-6)/r=c
The slope in terms of r and s is:
(s-6)/r.
