Answer:
9p+3r−7
Step-by-step explanation:
=3r+12p+−7+−3p
Combine Like Terms:
=3r+12p+−7+−3p
=(12p+−3p)+(3r)+(−7)
=9p+3r+−7
Answer:
(a)23 (b)90 (c)3
Step-by-step explanation:
The equation for the line of best fit for this situation is given as
where x=average temperature in degrees
y=average number of hot dogs she sold,
(a) The expected number of hot dogs sold when the temperature is 50° would be___hot dogs.
When x=50°
When the temperature is 50°, the expected number of hot dogs sold would be 23.
(b)If the vendor sold 35 hot dogs, the temperature is expected to be ___degrees.
If y=35
Multiply both sides by 10/3
If the vendor sold 35 hot dogs, the temperature is expected to be 90 degrees.
(c) Based on the line of best fit, for every 10-degree increase in temperature, she should sell 3 more hot dogs.
Answer:
Step-by-step explanation:
hello :
let : f(x) this denominator :
12/x(x+4) = f(x)/x(x+4)(x-9)
f(x) =12x(x+4)(x-9)/x(x+4)
if : x(x+4)(x-9)≠0 simpify by : x(x+4)
f(x) = 12(x-9)
