Answer:

Value of the car is decreasing by 13.9% each year.

Step-by-step explanation:

This equation tells us V(t) is the value of the car after a certain time in years, $21,000 is the initial value of the car.  What we need to focus on is on the 0.861 part of this equation.  This means that the price of the car is worth 0.861 or 86.1% of what it was worth the year prior, this means that the price of the car is decreasing over time.  By how much is it decreasing? Well if we consider 1 to mean 100% (since 100 / 100 =1) then we have 100%-86.1%=13.9%.  This means that the value of the car is decreasing 13.9% each year.

\sf 2x^2 - 8x = - 7  \\  \\ Subtract \ -7 \ from \ both \ sides \ of \ the \ equation. \\  \\ 2x^2 - 8x - (-7 ) = - 7 - (-7)  \\  \\ 2x^2 - 8x + 7 = 0  \\  \\ Use \ quadratic \ formula \ a = 2, b = -8, c = 7 \\  \\ x =  \dfrac{- b \pm \sqrt{b^2- 4ac} }{2a}  \\  \\  \\ x =  \dfrac{-(-8) \pm \sqrt{(-8)^2 - 4 (2) (7) } }{2(2)}  \\  \\ x =  \dfrac{8 \pm  \sqrt{8} }{4}  \\  \\ x = 2 +  \frac{1}{2}\sqrt{2} \ or \ x = 2 +  \frac{-1}{2}  \sqrt{2}

PLEASE HELP I WILL GIVE BRAINLIST PLEASE
ivolga24 [154]

Answer: D: 4.5

Step-by-step explanation:

So the Equation I used for this would be

6(2x+3) = 3(6x-3)

In Which the left is the Hexagon (The 6 is for the 6 Sides) and the right of the equation is the triangle (given the 3 for the 3 sides. In order to solve, we need to solve for x. Distribute the equation and your left with

12x+18=18x-9

-12x            +9

27=6x

Divide to get X by itself

and your left with

4.5 = x

Hope it helped.

The second side of the triangle deck is 4 feet longer than the shortest side. The third side of the deck is 4 feet shorter than
mestny [16]

Answer:

Step-by-step explanation:

let s = the length of the shortest side

:

Write an equation for each statement

:

The second side of a triangular deck is 4 feet longer than the shortest side

(s+4) = the 2nd side

and a third side that is 4 feet shorter than twice the length of the shortest side.

(2s-4) = the 3rd side

:

If the perimeter of the deck is 48 ​feet, what are the lengths of the three​ sides?

s + (s+4) + (2s-4) = 48

Combine like terms

s + s + 2s + 4 - 4 = 48

4s = 48

s = 48/4

s = 12 ft is the shortest side

:

:

I'll let you find the 2nd and 3rd sides, ensure they add up to 48
