Answer:
d1= -d2+M
Step-by-step explanation:
you would multiply d1 and d2 by 1/2, then add negative d2/2 to each side, then divide each side by 2/1.
hope it helps
mark me brainliest pls
Answer:
Step-by-step explanation:
So, we have the graph y=f(x).
And we want to find:
Remember that the inverse of a function is simply the x-values and y-values swapped. To see this, let's let our inverse equal y:
This means that we have the point:
So, to find our solution, we will swap the x- and y-coordinates. This gives us:
So, simply need to find the x-coordinate such that y is 0.
From our graph, we can see the point (6,0). In other words:
So:
And we're done!
Answer:
y=3/2x - 5
Step-by-step explanation:
Subtract the 2y to move it to the other side
Subtract the 3x to move it to the other side
you get the equation of -2y=-3x + 10
Divide by -2
In order to know at what price the two services offered would be the same, we can actually use the process of trial and error starting from 1 onwards. The first one is 50.45 per month plus a standard fee of 60 for installation. So this will be 60+50.45x (number of days). After that. there is the other one that has free installation but charges 57.95. So it can be expressed as 57.95x. Now after trial and error with numbers as x, I came upon 8. If x is 8, then the first one will be 60+50.45 (8) = 463.6. For the second, 57.95(8) will also equal to 463.6. So the day in which the two services will charge the same is during the 8th day.
