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
Factor 3d out of 6d^2 -21d

Answer:
a
Step-by-step explanation:
225*1.7=382.5
Answer:
48pi or ~150.8
Step-by-step explanation:
ok so area = pi * r^2
r = 8
8^2 = 64pi
so 64/4 = 16
16*3 quarters shaded = 48
48pi is the answer
48pi or ~150.8
The possible outcomes are {1, 2, 3, 4, 5, 6}. Of these outcomes, {4, 5, 6} are greater than 3. So P(rolling a number > 3 is 3/6, or 1/2, or 0.5.
