Answer:
A. For the graph, the rate of change is -2 and for the equation, it is 2.
Step-by-step explanation:
The rate of change of the line on the graph can be found by considering the rise or fall when moving one unit to the right. This line falls 2 units for each unit to the right, so its rate of change (slope) is -2.
The rate of change of the equation can be found by looking at the coefficient of x. It is 2.
So, the appropriate description is ...
For the graph, the rate of change is -2 and for the equation, it is 2.
For part A, the majority of dots circled are what's called a cluster. The one point out by itself is called an outlier. As for part B, it seems that as the hours of computer games played go down, their test scores go up.
hope it helps.
Assuming that x is on the horizontal and y on the vertical y = 35*x so the second option
The diagonal of a rectangle is:
d ^ 2 = w ^ 2 + l ^ 2
Where,
w: width
l: long
Substituting values we have:
(l + 2) ^ 2 = (l-7) ^ 2 + l ^ 2
Rewriting we have:
l ^ 2 + 4l + 4 = l ^ 2 -14l + 49 + l ^ 2
l ^ 2 -14l + 49 - 4l - 4 = 0
l ^ 2 -18l + 45 = 0
(l-15) (l-3) = 0
The solutions are:
l = 15
l = 3
The viable solution is:
l = 15
Thus, the width is:
w = l-7
w = 15-7
w = 8
Answer:
the dimensions of the rectangle are:
l = 15
w = 8
It should be 5,000,000 = 5 × 10^6 and the other one would be 0.0000009 = 9 × 10^-7
