Answer:
4
Step-by-step explanation:
To find the rate of change for the increase (warm up), use the coordinate pair of any two points on the line that slopes upwards in the graph.
Let's use the following:
At 5 mins (x), heart beats (y) is 80 => (5, 80)
At 10 mins (x), heart beats (y) is 100 => (10, 100)
Rate of change = 
Rate of change is 4.
Answer:
Step-by-step explanation:
area of a square = S x S
side = ⱱarea
side = ⱱ100
side = 10cm
perimeter = 4s
= 4 x 10
=40cm
What is asked here is that you isolate y so that the equation takes the form of y = ..., where ... will be something that contains a, b and c but not y. So how do we get there? By applying some standard permutations to equations like so:
aby - b = c
First, we bring the -b term to the right hand side by adding b left and right:
aby -b+b = c+b
The -b and +b cancel out, so we get:
aby = c + b
Then, we divide left and right hand side by ab:
aby/ab = (c+b)/ab
Again, the ab/ab on the left cancels out (it is 1), so we get:
y = (c+b)/ab
And we're done!
So you have to know that it is allowed to add or subtract something (anything) to/from the left and right hand side of an equation. Likewise, you have to know that it is allowed to multiply or divide by something, as long as it isn't 0.
