The temperature at 9:00 a. m. was 4°C. At 7:00 p. m., the temperature was -12°C. What was the change in temperature (in degrees Celsius)?
�� 8-degree decrease
�� 16-degree decrease
�� 8-degree increase
�� 16-degree increase

16-degree decrease

Step-by-step explanation:

Take the final temperature of -12   and subtract the initial temperature of 4

-12 - 4

-16

The change in temperature is 16 degrees

The minus sign tells us it was a decrease

i think 16 degree decrease

sorry if im wrong i tried to help

is should be y = 5x

step-by-step explanation:

correct me if im wrong

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
