$9x-3y=15\ \ \ | subtract\ 9x\\\\
-3y=-9x+15\ \ \ | divide\ by\ -3\\\\
y=3x-5\\\\
y=ax+b\ \ a-\ slope\\\\
a=3\\\\Slope\ is\ equal\ to\ 3.$

At a certain electronics company, the daily output Q is related to the number of people A on the assembly line by Q=600+√(A+41).

Ber [7]

Answer:

$A=400\ people$

Step-by-step explanation:

we have

$Q=600+\sqrt{A+41}$

where

Q -----> is the daily output

A -----> is the number of people

For Q=621

Find the value of A

substitute and solve for A

$621=600+\sqrt{A+41}$

Subtract 600 both sides

$621-600=\sqrt{A+41}$

$21=\sqrt{A+41}$

squared both sides

$21^{2} ={A+41}$

$441={A+41}$

Subtract 41 both sides

$441-41=A$

Rewrite

$A=400\ people$
