Number 3 using table is 0.59, 3.41
Graphed on calculator and changed the table set to increments of .1 all the way to .000001 to estimate where the zeros where.
Number 1,2,4,5 are displayed in attachment.
Umm... no...... I'm in Middle School but sorry though.
Proportion A
The first thing you should know in this case is what the rate of change means.
The rate of change in a linear equation is given by the slope of the line.
For a linear equation, the rate of change is constant.
So we have to:
y = 9x
The slope is:
m = 9
Proportion B
The slope of the line will be:
m = (y2-y1) / (x2-x1)
Substituting values:
m = (57.5-34.5) / (5-3)
m = 11.5
Answer:
The rate of change in proportion A is 2.5 less than in proportion B.
Answer:
Step-by-step explanation:
Minutes is the x axis, and Distance is the y axis.
At 1 minute it looks like Cassie ran much less than 20 yards and Hector ran much further than 20 yards, so Hector started running faster.
Looking at the y axis at 100yards, it looks like Cassie finished at exactly 5 minutes, but Hector only made it to 80 yards. So Cassie won because it was a 100-yrd race.
You can see Hector stopped and rested for 1 minute once he reached 60-yrds. He stopped after 2 minutes.
