Answer:
x=6,y= 7
Step-by-step explanation:
-6x +7y= 13
-6x+8y=20
-y = -7
divide through by -1
y =7
sub y= 7 in equation 1
then x= 6
Answer:
4x + y =6
Step-by-step explanation:
Line 8x + 2y = 12 is parallel to the line 4x + y = 6.
Add 12 to both sides:
5r^2 = 80
Divide by 5:
r^2 = 16
Square root both sides:
r = +/- 4
The answer is {+/- 4}.
For this case we have that by definition, a direct variation is given in the form:
Where:
k: It is the constant of proportionality
According to the statement we have to:
Substituting:
On the other hand we have:
