Hopefully this helps ya out but I may be wrong so please don't get angry.
Answer:
The linear equation is the equation of straight line. where m is the slope of the line and c is the y-intercept. Thus, the y-intercept is expressed as (0, c). That is where the graph intercepts the y-axis (thus, the x value would be 0).
Step-by-step explanation:
Answer: the rate of the passenger train is 100 mph.
Step-by-step explanation:
Let x represent the rate of the passenger train.
The rate of the freight train was 10 miles per hour slower than the rate of the passenger train. It means that the rate of the freight train is (x - 10) mph
The passenger train traveled 100 miles. It means that the time it took travel 100 miles is
100/x
In the same amount of time, it took a freight train to travel 90 miles. It means that the time it took travel 90 miles is
90/(x - 10)
Since the time is the same, then
100/x = 90/(x - 10)
Cross multiplying, it becomes
100(x - 10) = 90x
100x - 1000 = 90x
100x - 90x = 1000
10x = 1000
x = 100 mph
Answer:
C. f(x) and g(x) are the same when x = 2
Step-by-step explanation:
FINDING F(X)
If you plug in x = 2 into f(x) = x+ 1, we get the expression:
x + 1
= 2 + 1
= 3
FINDING G(X)
By looking on the graph, we see that g(2) = 3.
Since they both equal 3 when x=2, the answer choice is C: f(x) and g(x) are the same when x = 2.
Answer:
21,637
Step-by-step explanation:
You can just use a caculator- Or simple multiplication by putting it on top of eachother.
You can do this many ways,just multiply with pen and paper,put 250 on top,and 85 on bottom which is 21,250,the add from there!
Hope I helped!!
