How do i do this problem? I'm confused.

z is greater than or equal to 8

Step-by-step explanation:

for the graph you will have an open dot ( i think) with the arrow going up

to solve combine like terms then solve like a reg equation

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

what level of math? also i don't need to be paid if i can you.
