Answer:

Step-by-step explanation:

4 + 3(x + 5)=5 x - 7

3x + 19=5x - 7

3x + 19 - 19=5x - 7 - 19

3x =5x - 26

3x - 5x=5x - 26 - 5x

-2= -26

-2x/-2 = -26/-2

x= 13

It might be wrong. I may have made a mistake with typing sorry.

Hope this helps a bit.

Find a common denominator for 2,4,8. Which is 8. Change the fractions to new ones.

1) 19 4/8= 156/8 Then add the second. 2) 7 5/8= 61/8 one and the third
3) 5 6/8= 46/8 one. Which is

15/8. Then, subtract your answer and the first one. You get 141. Simplify. 17 5/8

Find an equation of the tangent line to the curve 2(x2+y2)2=25(x2−y2) (a lemniscate) at the point (−3,1). An equation of the tan

valina [46]

$2(x^2+y^2)^2=25(x^2-y^2)$

Let $y=y(x)$ , so that differentiating both sides wrt $x$ gives

$4(x^2+y^2)\left(2x+2y\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(2x-2y\dfrac{\mathrm dy}{\mathrm dx}\right)$

If $x=-3$ and $y=1$ , the above reduces to

$40\left(-6+2\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(-6-2\dfrac{\mathrm dy}{\mathrm dx}\right)\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac9{13}$

This is the slope of the tangent line, which has equation

$y-1=\dfrac9{13}(x+3)\implies\boxed{y=\dfrac{9x+40}{13}}$
