Answer:2/5c

Step-by-step explanation:

(a+b)/(a-b) =c

(a-b)/(a+b)=1/c

Multiply both sides by 2/5

2/5 x (a-b)/(a+b)=2/5 x 1/c

2(a-b)/5(a+b)=2/5c

Use the formula a^(x/n) = (n)√a^x (note it is a small n)

(5x^4y^3)^(2/9) = Small 9

Convert.

$\sqrt{9{{(25x^{8})y^9 }}}$ is your answer

hope this helps

Pls help me in these two little exercises about the slope.

den301095 [7]

Answer:

3) $y=\dfrac35x+\dfrac25$

4) a) $y=-2x+7$

b) $y=\dfrac12x+\dfrac92$

Step-by-step explanation:

Exercise 3

$-3x + 5y = 2$

$\implies 5y = 3x + 2$

$\implies y=\dfrac35x+\dfrac25$

Exercise 4

a) If L2 is parallel to L1, it has the same slope (gradient) ⇒ $m = -2$

If L2 passes through point (3, 1):

$y-y_1=m(x-x_1)$

$\implies y-1=-2(x-3)$

$\implies y=-2x+7$

So L2 = L1

b) If L3 is perpendicular to L1, then the slope of L3 is the negative reciprocals of the slope of L1 ⇒ $m = \dfrac12$

If L3 passes through point (-5, 2):

$y-y_1=m(x-x_1)$

$\implies y-2=\dfrac12(x+5)$

$\implies y=\dfrac12x+\dfrac92$
