Answer:
Linear
Step-by-step explanation:
For every step in x, the y values increase by 4 each time, making it a linear function, since the change in y is constant.
For this we will use equation:
H = starting height + rate_of_growth*periods
We can mark H with index w to represent how many weeks have passed.
Because all of this we can write:
Hw = 200 + 0.5*w
To calculate height after some number of weeks all you need to do is to exchange w with number of weeks.
Answer:
-2y
Step-by-step explanation:
Let's simplify step-by-step.
x−y−(x+y)
Distribute the Negative Sign:
=x−y+−1(x+y)
=x+−y+−1x+−1y
=x+−y+−x+−y
Combine Like Terms:
=x+−y+−x+−y
=(x+−x)+(−y+−y)
=−2y
Answer:
6.5
Step-by-step explanation:
first subtract 7 from both sides
2x=13
next divide both sides by 2
x=6.5
