Answer:

Step-by-step explanation:

Using the parallelogram theorem

3x-8 = 10x+13

-7x = 21

x = -3

Substitute

3(-3) - 8

-17

10(-3) + 13

-17

Marysya12 [62]

Answer:

10 km

Step-by-step explanation:

The Angle formed by their travel is a right angled triangle (check attached picture) , hence we can apply Pythagoras rule :

Hypotenus = sqrt(opposite² + Adjacent²)

Hypotenus = distance hiked after lunch :

D = sqrt(6² + 8²)

D = sqrt(36 + 64)

D = sqrt(100)

D = 10 km

Answer: c) y = ln(5x) - 2

<u>Step-by-step explanation:</u>

$y=\dfrac{1}{5}e^{x+2}\\\\\text{Swap the x's and y's. Then solve for y:}\\\\x=\dfrac{1}{5}e^{y+2}\\\\\\\text{Multiply both sides by 5:}\\5x=e^{y+2}\\\\\\\text{Apply ln to both sides:}\\ln(5x)=ln\ e^{y+2}\\\\\text{Simplify:}\\ln(5x)=y+2\\\\\\\text{Subtract 2 from both sides:}\\ln(5x)-2=y$
