Answer:
y= -x+7, b= sqrt(2P/a), c=3P^2-b
Step-by-step explanation:
First, make a table regarding both of the equations. You will eventually find out that both lines intersect at the point (2, 5) after you find the points on the table. From there, subtract x from both sides in the equation x + y = 2. You will get y = -x + 2. Since they said the line was parallel, find a line that has the slope of negative one. Since we know that this line intersects the point in which the first two lines intersect, we know that the y-intercept will be 7. The equation of the line would be y=-x+7.
Multiply both sides by 2. Then, divide both sides by a to get b^2=(2P/a). Take the square root to get the value of b, which is sqrt(2P/a).
Square both sides of the equation to get P^2=(b+c)/3. Cross multiply to get 3P^2=b+c. Subtract b from both sides to get c=3P^2-b.
If the problem says by or divided by
Answer:
0, 1, 2
Step-by-step explanation:
So, since there are three consecutive integers, you have the equations
x, x+1, x+2 where x is the smallest number.
The greatest of the three integers= x+2
Finish setting up your equation;
2(x+x+1)=x+2
Combine like terms;
2(2x+1)=x+2
Distribute;
4x+2=x+2
3x=0
x=0
x+1=1
x+2=2
Hope this helps:) Have a good day!
