20 pages per day
so the variable attached to the number 20 would be "number of days"
so x represents the number of days
then 90 + 20(number of days) = (total number of pages)
so that makes f(x) = (total number of pages)
therefore your answer is 2.
Answer:
B
Step-by-step explanation:
Answer:
rate of change=slope= y2-y1/x2-x1
Step-by-step explanation:
x: -2|-1|0|1
y : 5|4|3|2
so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)
now we plug them in: 
4-5=-1
-1-(-2)=1
so -1/1 is equal to -1, meaning it's answer option b.
So 1 quater is 25 cents each. 5 quaters would be 125 cents. We know that 4 quaters equal $1.00 So we now have 1 quater left, you can add 25 cents to one dollar and get $1.25
So we started off with 125 cents so we added in a decimal point and added in a dollar sign. Hope this helps.
Answer:
it 25 because 10 add 5 is 15 add 7 is 22 ads 3 is 25 so that why it 25
