Answer:
-70x + 21
Step-by-step explanation:
1-8(10x-3)
-7(10x-3)
Use distributive property
-70x + 21
(This is how we learned to do it in my school)
Ok then after that what’s the question ?
Answer:
-3.
Step-by-step explanation:
In the table, the y value goes down by -4 and then -2, for a total of -6.
We did this over a period of two units (To go from -1 to 1, we add 2).
-6/2 = -3.
-3 is the average rate of change over the interval.
Answer:
C
Step-by-step explanation:
if you put the x numbers (miles) in the x spot in the equation you will get your y answer. which ever one matches is your answer
add 0+1+2+3+4 = 10
divide 10÷5 = 2
add 15+8+3+3+1 = 30
divide 30÷5 = 6
the ratio is 2:6 which simplifies to 1:3 by the means of lates per student. In other words there is one late per 3 students.
