When a line is perpendicular, the slope is the negative reciprocal. Therefore, since the slope is 4, the slope of a line perpendicular is -1/4
Answer: X= -1
Step-by-step explanation: In this equation you want to solve for "x"
You subtract 6-6=0 leaving "x" by itself. So the equation will look like this: 6x= -6
After this you want to divide by 6 to one side and to the other equaling "x" as -1
Answer:
A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.
Step-by-step explanation:
Given
Required
A good first step
A good first step is to eliminate x and this is done as follows:
Multiply by 2 (gotten from coefficient of x in the second equation)
Multiply by 3 (gotten from coefficient of x in the first equation)
This gives:
Add both equations
<em>Hence (a), is true</em>
If your asking about the max amount of minutes he can have in the month without going over 40$ then the answer is 240.
40-15.95= 24.05
24.05/.10= 240.5
Since it has to be a whole minute then it would be 240
