Volume of cube = ( side)^3
Side = 6 feet = 6×12 = 72 inches ( 1ft =12 inch)
Vol. = (72)^3 = 72×72×72= 373248 cubic inches
So you always want y in front of the equation no matter what so you have x +2y=5 so you take the x and you subtract it to both side making it 2y= 5-x so then you just have to take the 2 to both side so you have to divide it and you will get y= 5/2-x/2 so then to graph it you start with the b which is -x/2 so you go down -1 and over 2 and place your dot adn then go up 5 over 2 and then place you dot and connect them together
If the data is negative or decreasing
Answer:
x=1
y=1
(1,1)
Step-by-step explanation:
TO SOLVE FOR X:
1. Substitute. You should start off by looking like this:
x=2x-1
2. Subtract 2x from both sides:
-x=-1
3. Make x positive by multiplying both sides by -1:
x=1
TO SOLVE FOR Y:
1. Substitute x into original statement:
y=2(1)-1
2. Simplify:
y=2-1
3. Simplify:
y=1
TO CHECK YOUR ANSWER:
1. Take other original statement and stubstitute answers. It should look like this:
y=x
1=1
2. Does 1=1?
Yes so the answer is correct
3. Final Answer is:
x=1
y=1
(1,1)
Solutions are 3 and - 5.
Step-by-step explanation:
Step 1:
Given equation is 3x² + 6x = 45. Factorize the equation to get the solutions.
⇒ 3x² + 6x - 45 = 0
⇒ x² + 2x - 15 = 0
⇒ x² + 5x - 3x - 15 = 0 (Product and Sum Method where product of coefficients = - 15 and sum = 2)
⇒ x (x + 5) - 3(x + 5) = 0
⇒ (x - 3)(x + 5) = 0
⇒ x = 3, - 5
