Website 1 : y = 1.50x + 30
website 2 : y = 2x + 0...or just y = 2x
=======================
y = 4x - 4
y = -4x + 4
4x - 4 = -4x + 4
4x + 4x = 4 + 4
8x = 8
x = 1
y = 4x - 4
y = 4(1) - 4
y = 4 - 4
y = 0
so this is a consistent system because it has one solution (1,0)
The value of the stock ABC over a period of 47 days is $4474.03.
<h3>What is a scatterplot?</h3>
A scatterplot is used to show the relationship between two variables. The variables are plotted on Cartesian axes.
First, we must determine the fitness of the line to show if it is linear. We can get this from r^2 = (0.9948)^2 = 0.9896. This value is close to one hence the line is linear.
Thus;
y= 94.38x+ 38.17 and x = 47 hence
y= 94.38(47)+ 38.17
y = $4474.03
Missing parts:
Equation y = 94.38x + 38.17 fits the scatterplot of the values for stock ABC over the past month with an r-value of 0.9948. How much do you think ABC will be worth at x = 47 days?
A.$94.38 B
.$4474.03 C
.$4752.31
D.$38.17

Answer:
Average rate of change is <u>0.80.</u>
Step-by-step explanation:
Given:
The two points given are (5, 6) and (15, 14).
Average rate of change is the ratio of the overall change in 'y' and overall change in 'x'. If the overall change in 'y' is positive with 'x', then average rate of change is also positive and vice-versa.
The average rate of change for two points is given as:
Plug in and solve for 'R'. This gives,
Therefore, the average rate of change for the points (5, 6) and (15, 14) is 0.80.
