Answer:
a. A minimum of 300
Step-by-step explanation:
If her bill is $142 then it is a sum of the flat rate plus the money she pays for all the smses she sent. As an equation, it can be expressed this way
106 + 0.12x = 142 where x is the number of smses
0.12x = 36
x = 300 smses
So if we were told that she pays $142 per month, we'd know that she sends 300 smses. But we are told she pays AT LEAST $142 so there is a possibility that she sends even more than 300 smses
Answer:
After 15 years the use of said machine is no longer profitable
Step-by-step explanation:
it should be used, as long as the money generated is not smaller as the costs generated. By setting both formulas equal (calculating the x value for when they are equal) you get x = 15 and x = -2.5(which doesnt make sense in this context).
Answer:
yeah, (891)+(038)=(193994)

I'll help anytime you need
So this... is a slightly complicated problem you have to set up an equation.... so 7x-12=2x+8 you subtract 2x and add 12 to both side so now you have 5x=20 now divide both sides by 5 now you have x= 4 so plug it into the problems for the sides 2(4)+8= 14 is the length of one side and 7(4)-12=16 so 16 is the length for the other now you just pick the measurement to use hope this helped!!!!! have an amazing day!
Every function associates input values with output values. The domain of a function is the set of all the inputs the function accepts.
You will basically always find your function graphed with the inputs on the horizontal axis and the outputs on the vertical axis. This means that every point on the graph has coordinates 
, and the domain is the set of all the x values.
The points on your red line have all coordinates 
, where d starts from 0 and ranges up to 12. So, the domain of the function is ![[0,12]](https://tex.z-dn.net/?f=%20%5B0%2C12%5D%20)
