If we multiply the first equation by 2 we get
2x - 4y = 12
but the second equation is
2x - 4y = 10
2x - 4y can't have 2 different values so the are no solutions
Answer:
x=5
Step-by-step explanation:
If ABCD is a parallelogram, then AB = CD
AB=CD
6x-10 = 3x+5
Subtract 3x from each side
6x-3x -10 = 3x-3x+5
3x-10 = 5
Add 10 to each side
3x-10+10 = 5+10
3x = 15
Divide by 3 on each side
3x/3 =15/3
x=5
Answer:
We have the equation of the line as : 4x+2y=12
Step-by-step explanation:
Now 4x+2y=12
=> 2y = 12 - 4x
=> y = 6 - 2x
A line with a slope m and y-intercept c can be written as y = mx + c
In the case of y = -2x -...
You can use substitution here. First, get y alone:
14x + y = -4
subtract 14x from each side
y = -4 - 14x
Then, plug y into the second equation
-4 - 14x = 3x² - 11x - 4
then solve from there
Hope this helps :)
Supplementary angles add to be 180 degrees. If one angle is 20. The supplement angle is 160.
180 - 20 = 160
160 is your answer.
