Answer:
divide by x
Step-by-step explanation:
To answer your question, you can get from A to B by dividing by x:

However, this is only a valid operation if x ≠ 0. In this equation, x = 0, so that division is not valid.
__
A better approach to the solution is to put the equation in standard form:
f(x) = 0
You can get there by subtracting 3x from both sides.
5x -3x = 3x -3x
2x = 0
Now, you can legitimately divide by 2 to find ...
x = 0 . . . . . . . . the reason why dividing by x is not allowed
Answer:
y=-x-2*-3
Step-by-step explanation:
Answer:
(- 2, 9 )
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ), thus
(9, - 2 ) → (- 2. 9 )
Answer:
$12x + $33.75
Step-by-step explanation:
Okay so if you have (16x + 58.75) - (4x + 25)
first you add the common variables so... 16x - 4x = 12x
and 58.75 - 25 = 33.75
And 1 the most common mistake is that people add 25 and 58.75. The reason you don't do this is because the two equations are subtracting or trying to find the difference regardless of whether the numbers are positive or not. Although if they were negative numbers you would be adding.
I hope this helps :)
Answer:
B. 4.0 liters
Step-by-step explanation:
1 can = 0.4 l
10 cans = 0.4l x 10
0.4l x 10 = 4l
10 cans = 4l
