If you are asking for the formula thing, it is
y=3x+2
Answer:
a) 3 people will need 35 days to paint the bridge
b) p=105/t
Step-by-step explanation:
a)
We have 7 people each one is to work 15 days, so the bridge needs a total of 7(15) days of work
7(15)=105
Then we have 3 people each one is to work t days, altogether should do a total of 105 days of work
3(t)=105
Solve for t
t=35
b)
Substitute p for 3 in the second equation
p(t)=105
Solve for p
p=105/t

Step-by-step explanation:
Hope i am not wrong
f(x)=4x+1
g(x)=x^2-5
(f-g)(x)=f(x)-g(x)
(f-g)(x) =4x+1-x^2+5
-(x^2-6-4x)
solve it for x
Answer:
You are differentiating with respect to x
with the formula X^n = nX^n-1
dy/dx= 12x2 - 24x + 14
