4w-7k=28
-7k+4w+-4w=28+-4w
-7k=-4w+28
-7k/-7=-4w+28/-7
k=4/7w-4

Answer:
7 inches
Step-by-step explanation: Every 1 inch = 50 miles. So every 50 miles of tunnel is 1 inch in a scale drawing. 350miles/50 miles=7 inches.
The scale drawing is 7 inches.
A<em>Graph g</em>
The Rate of change is a little right triangle that is drawn from to to three parallel to the x axis and from about 45 to 60 on the y axis.
The square brackets means the the endpoints are included.
So the rate of change is

<em>Graph h</em>

<em>Graph f</em>

<em>Conclusion</em>
This is very hard to call. There are two the same (two of them being g and h) It's a graph and so it is nearly impossible to differentiate. I would say the statement is false but be prepared to get it wrong. Draw g and h for yourself and see what you think. If you get the two of them different, go with your answer.
BAnother tough one to call. f and g cross at four. It is true f and h. The value of f(4) > h(4). Again, if you do this and disagree, then go with your answer. Mine is false.
CIt is very difficult to reproduce this graph on desmos so that you get a clear cut answer from the graph. I cheated and used a calculator. f(x) is over 6000 and h(x) = 168. This statement is also not true.
DHere again this is false. g's rate of change is a constant. Eventually f will have the same slope as bitcoin's value which is in the range of about 6000. So this statement is false as well.
ESee the comment about F in the answer for D. This statement is true.
FThis is definitely a true statement.
Conclusion or answer
E and F <<<<<<<
True should be checked.
I would check the first two statements with a calculator. I did them with a graph.
M+2/3=1/2
<=> m= 1/2 - 2/3
<=> m= -1/6
The answer should be 5 degrees. The temperature starts at 8 degrees and decreased to 3 degrees. Therefore you find the missing addend which in this case is 5 degrees. 8-3=5
