Answer:

\frac{-4xy}{x^2-y^2} is the answer

Step-by-step explanation:

\frac{x-y}{x+y} -\frac{x+y}{x-y}

making denominator same

\frac{(x-y)(x-y)}{(x+y)(x-y)} -\frac{(x+y)(x+y)}{(x-y)(x+y)}

\frac{(x^2+y^2-2xy)}{x^2-y^2} -\frac{(x^2+y^2+2xy)}{x^2-y^2}\\\frac{x^2+y^2-2xy-x^2-y^2-2xy}{x^2-y^2}\\\frac{-4xy}{x^2-y^2}

Determine the slope-intercept form of the equation of the line parallel to y = x + 11 that passes through the point (–6, 2).
MArishka [77]
Line parallel to y=x+11 so slopes are equal then
y= x+b
Passing through the point C (-6;2) then C belongs to this line
yc=xc+b
b= 6+2
b= 8
So y intercept is equal to 8

Answer:

The y-intercept is b=0

The y-intercept represents the initial quantity of gas in the canister which is zero.

Step-by-step explanation:

The y-intercept is where the graph of the straight line  touches the y-axis.

From the graph, the y-intercept is the origin (0,0).

Recall that the slope intercept form of a straight line is y=mx+b, where b=0 is the y-intercept in this case.

Since the graph represents the amount of gasoline in a canister after Joshua begins to fill it at the gas station pump, the y-intercept means the initial gallons of gas in the canister is zero.

Logan measured a line to be 7.4 inches long. If the actual length of the line is 7.7 inches, then what was the percent error of
Tanzania [10]

Answer:

4.0541

Step-by-step explanation:

I don't know if this is correct but this is what I got.

You would take the error and divide it by the theoretical value and then multiply that by 100.

7.7 - 7.4 = 0.3

0.3 ÷ 7.4 = 0.04054054

0.04054054 x 100 = 4.05405405 (simplify) = 4.0541%

Hope I helped in any way
