Common difference r will be the difference between next two values of number row, so we take e.g. second minus first: r=9.4-6=3.4. You can see, that this value is constant as we go through next pairs of values.
Domain means the “input” which is like when u input a number in a vending machine and then the output is you getting the chips or whatever u got from imputing the number. So the answer would be C because is is asking for the front numbers in the relation or plots of points.
Answer:
Ayo its ( $6.40 )
Step-by-step explanation:
I did it for my do now once.
Let p represent # of physics texts sold
Let m represent # of maths texts sold
Therefore we have p = m - 60 | because physics texts sold are less than maths by 60
Total sold = 206 = m + p | recall that p = m - 60
We then have 206 = m + m - 60
206 = 2m - 60 | adding 60 to both sides, we have
206 + 60 = 2m | dividing both sides by 2
266/2 = 2m/2
Therefore, m = 133 texts
and p = m - 60 = 133 - 60 = 193
