Sequence one is geometric since you are multiplying each number by a certain value (-2). Sequence 2 is arithmetic since you are adding each number by -20

Find the slope of the line passing through the points (-5,1) and (2,4).

Leno4ka [110]

Answer:

<h3> $\boxed{ \bold{ \huge{ \boxed{ \sf{ \frac{3}{7} }}}}}$ </h3>

Step-by-step explanation:

Let the points be A and B

A ( -5 , 1 ) ⇒( x₁ , y₁ )

B ( 2 , 4 )⇒( x₂ , y₂ )

Finding the slope of the line passing through these Points

Slope = $\sf{ \frac{y2 - y1}{x2 - x1} }$

plug the values

⇒ $\sf{ \frac{4 - 1}{2 - ( - 5)} }$

We know that $\sf{( - ) \times ( - ) = ( + )}$

⇒ $\sf{ \frac{4 - 1}{2 + 5} }$

Subtract 1 from 4

⇒ $\sf{ \frac{3}{2 + 5} }$

Add the numbers

⇒ $\sf{ \frac{3}{7} }$

Hope I helped!

Best regards!!

Y=e^x how do I solve this

kolezko [41]

If you're trying to solve for x, keep in mind the ln (natural log) of e is 1. So take the natural log of both sides, which will give you ln Y = ln e^x. The ln and e essentially cancel out, so you're left with x = ln Y.

A boat costs $11,850 and decreases in value by 10% per year. How much will the boat be worth after 8 years?

arsen [322]

11,850 x .9 = 11,605

11605 x . 9 = 9,598.5   year 2

9,598.5 x .9 = 8,638.65

8,635 x .9 = 7,774.785 year 4

7,774.785 x .9 = 6,997.31

6,6997.31 x .9 = 6297.58   year 6

6297.58 x .9 = 5,667.82

5,667.82 x .9 = 5,101.04 year 8

The answer is D
