Answer:

slope \ of \ y = 2x + 5 , m_{1} = 2\\\\Let \ the \ slope \ of \ the \ new \ line \ be  \ m_{2} \\Since \ the \ lines \ are \ parallel \ m_{1} \cdot m_{2} = 1\\

That \ is \ 2 \cdot m_{2} = 1 =>  m_{2} = \frac{1}{2}

Equation of line passing through (2, -4)

y-(-4)= \frac{1}{2} (x - 2)\\\\

y+4 = \frac{1}{2} ( x - 2)\\\\2y + 8 = x - 2\\\\2y = x -10\\y = \frac{1}{2} x -5

-2-3(a)=-23<br> Please answer this with how you got the answer.
Kruka [31]

Answer:

a = 7

Step-by-step explanation:

» <u>Solution</u>

Step 1: Add 2 to both sides.

  • -3a-2+2=-23+2
  • -3a=-21

Step 2: Divide both sides by -3.

  • -3a/-3=-21/-3
  • a=7

Therefore, a = 7.

an object is thrown off a platform that is 15 ft high with an initial velocity of 8.5 ft/is what function models the height h of
NemiM [27]

Answer:

Therefore the function that models the height of the object after t seconds is given by "H(t) = 15 + 8.5*t + 16.09*t²".

Step-by-step explanation:

Since the object has a initial velocity and it's being accelerated by gravity, than it's height is defined by:

H(t) = H(0) + V(0)*t + 0.5*g*t²

Applying the data from the problem, we have:

H(t) = 15 + 8.5*t + 0.5*32.17405*t²

H(t) = 15 + 8.5*t + 16.09*t²

Therefore the function that models the height of the object after t seconds is given by "H(t) = 15 + 8.5*t + 16.09*t²".

Divide the binomial by the monomial to find the quotient -36x^4y + 144x^2 y^6/ -4x^2y
elixir [45]
The way that you would do this is by taking -4x^{2} out of the binomial, or as I like to think about it, 'un-distributing'. :p
-4x^{2} out of -36x^{2}y, you end up with 12x^{2}. 
When you take -4x^{2} out of 144x^{2}y{6}, you get -36y^{5}. 
Put it together, and the solution is 12x^{2} - 36y^{5}.

Hope I helped!!
