You have the slope and you have two points, so you can use the slope equation to find x.

b=\frac{(y_2-y_1)}{(x_2-x_1)} \\2=\frac{(15-5)}{(x-3)} \\2(x-3)=(15-5)\\2x-6=10\\2x=16\\x=8

So your answer is x = 8.

Answer:

x =7

Step-by-step explanation:

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

for points (3,5) and (x,15)

that will be m= (5-15)/(3-x)

so (5-15)/(3-x) =2

-10 / (3-x) = 2 / 1 cross multiply

-10 = 2(3-x)  divide both sides by 2

-5 = 3 -x

x= 3+5 =8

Hello,

\dfrac{dy}{dx} = \dfrac{e^x}{e^y} \\&#10;&#10;e^y*dy=e^x*dx \\&#10;&#10;e^y=e^x+C\\&#10;&#10;if\ x=0\ then\ y=ln(3) ==\ \textgreater \  3=1+C==\ \textgreater \ C=2\\&#10;&#10;\boxed{y=ln(2+e^x)}\\&#10;&#10;

The length of a rectangular playing field is 5m longer than its width. If the perimeter of the field is 150m,find it's width​
Inessa05 [86]

Answer:

35

Step-by-step explanation:

Make equations, l = w+5 and 2l + 2w = 150

Substitute w+5 into 2l + 2w = 150

Simplify to get 4w + 10 = 150

Subtract 10 from both sides to get 4w = 140

Divide both sides by 4 and you get 35 as width
