Answer:
Step-by-step explanation:
Rate of change is another term for the slope.
rate of change = slope = (change in y)/(change in x)
<u>Function A:</u>
y = mx + b (m = slope)
y = 4x - 3
Function A has a slope of 4.
The rate of change for function A is 4.
<u>Function B:</u>
Take two points.
(-1, 0) and (1, 4)
slope = (y2 - y1)/(x2 - x1)
slope = (4 -0)/(1 - -1)
slope = 4/2 = 2
The rate of change for function B is 2.
X = 3 and y = 3. This can also be written as (3,3).
Answer:
They are equal.

Answers:
- A) The equation is d = 2t
- B) Independent variable = time; dependent variable = amount of cookies
=========================================================
Explanation:
The independent variable is always long the horizontal axis. Often this is x, but we are using t in this case.
The variable t represents the amount of time in minutes. For instance, t = 2 means 2 minutes have elapsed. At this time, 4 cookies have been eaten as shown by the point (2,4). As another example, the point (3,6) means that d = 6 cookies have been eaten at time t = 3 minutes.
The equation is d = 2t because the '2' represents the rate of change of "eating 2 cookies per minute". Whatever the time value (t) is, we double it to get the value of d, which is the number of cookies eaten.
Answer:
Step-by-step explanation:
Each of the squares has trinomials that factor. x^2 - 14x + 49 = (x - 7)^2
When you take the square root (to get the side length) you get x - 7. So the length of each square is x - 7) = 0;..........x=7 That's the answer to a.
The answer to b is the same. The width =7
It's a square both sides have to be equal.
The length of the rectangle when the two squares are put together is 7 +7 = 14.
Answer: Question a = 7..... Question b = 7 ......... Question C = 14
