You can reword the two equations as:
-5x-y=15 (Divide original value by 3)
-2x+6y=6
Then use elimination to find x:
-30x-6y=90 (Multiply by 6 to get y values to be same to cancel out)
-2x+6y=6
You're left with:
-32x=96. Which can then be solved to find x which is -3.
Then plug back in
-2x+6y=6
Now to: -2(-3)+6y=6.
Which reduces to 6+6y=6. So y=0.
To graph them, just reword the equations (yes once again) so that y is in front.
y=-5x-15 and y=(1/3)x+1
Answer:
Step-by-step explanation:
x² + 9x+8 = (x+1)(x+8)
Answer: False, x=14
Step-by-step explanation:
3(14) = 42
42+2=44
x=14
Answer:
is the answer is 8 and 15?
The factor of 100x to the power of 2 power -9 is 2.
