I really need help on this !!

Naddik [55]

Answer:

r = -1

Step-by-step explanation:

(y2-y1)/(x2-x1)=m

(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5

so plug in...

(4-7)/(4-r)=-3/5

then solve for r which will get that r = -1

numerator: 4-7=-3

denominator: 4-r=5 -> 4-5=0+r -> -1=r

Round of 38828 to the nearest 10

RUDIKE [14]

Step-by-step explanation:

We're going to be evaluating if we can round 2. (Values in the 10's place)

The value in the 'ones' place has to be greater than or equal to 5 in order to round up 2.

Since 8 is greater than 5, we can round up 2.

Rounded answer:

38830

Giải các phương trình vi phân sau y' - y/x+1 = 2

KatRina [158]

It looks like the differential equation is

$y'-\dfrac y{x+1}=2$

Multiply both sides by 1/(x + 1) :

$\dfrac{y'}{x+1}-\dfrac y{(x+1)^2} = \dfrac2{x+1}$

The left side is now a derivative of a product,

$\left(\dfrac y{x+1}\right)' = \dfrac2{x+1}$

Integrate both sides with respect to x :

$\dfrac y{x+1} = 2\ln|x+1|+C$

Solve for y :

$y = 2(x+1)\ln|x+1| + C(x+1)$
