Mathematics
1 answer:
Yuki888 [10]3 years ago
6 0

Answer:

A.

Step-by-step explanation:

Subtract -4x on both sides to get to -2y=-4x-8, then you should divide -2 into both sides to get to the slope of y=2x+4 since two negatives would equal to a positive when dividing and multiplying.  Because the slope is positive, it is safe to assume that the first two options A and B are the best options due to their slopes being positive and going up.  The y-intercept is 4 which makes the answer A because on 0 it is on the positive side.

Which expression is equivalent to the following complex fraction? X+5/x+2-x+1/x^2+2x
ICE Princess25 [194]

Answer:

Final answer will be the choice which matches best with expression

\frac{x^2+4x-1}{x\left(x+2\right)} or

\frac{x^2+4x-1}{x^2+2x}


Step-by-step explanation:

Given expression is:

\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{\left(x^2+2x\right)}

We begin by factoring denominators:

=\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}

Multiply and divide first term by (x) to make denominators equal.

=\frac{x\left(x+5\right)}{x\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}

Since denominators are equal so we can combine numerators.

=\frac{x\left(x+5\right)-\left(x+1\right)}{x\left(x+2\right)}

Now simplify

=\frac{x^2+5x-x-1}{x\left(x+2\right)}


=\frac{x^2+4x-1}{x\left(x+2\right)}


=\frac{x^2+4x-1}{x^2+2x}

Hence final answer will be the choice which matches best with expression

\frac{x^2+4x-1}{x\left(x+2\right)} or

\frac{x^2+4x-1}{x^2+2x}

Solve y-4=3x+5y for y
liq [111]

y-4=3x+5y\qquad|\text{add 4 to both sides}\\\\y=3x+5y+4\qquad|\text{subtract 5y from both sides}\\\\-4y=3x+4\qquad|\text{divide both sides by (-4)}\\\\\boxed{y=-\dfrac{3x+4}{4}}
