2x + 4y = 14
4x + y = 20......multiply by -4
----------------
2x + 4y = 14
-16x - 4y = -80 (result of multiplying by -4)
---------------add
-14x = -66....as u can see, ur y's cancel out

so ur answer is : 1st answer choice <==

** and just so u know, u could have multiplied the 1st equation by -2, and it would have cancelled out ur x's

D(n)=-5(1/2)^n-1 what is the 3rd term in the sequence

Studentka2010 [4]

Answer:

-1.25

Step-by-step explanation:

Better to write this as

a(n)= -5(1/2)^(n-1)

Then the 3rd term is a(3) = -5(1/2)^(3 - 1), or a(3) = -5(1/2)^2 = -5/4 = -1.25

Grace's car left four skid marks on the road surface during a highway accident. Two of the skid marks were each 52 feet and two

Mashcka [7]

Answer:

The skid distance to be used is 54 feet.

Step-by-step explanation:

Given:

Four skid marks on the highway.

$52,52,56,56$ in feet.

We have to find the skid distance.

The skid distance that will be used to further calculate the skid speed is actually the mean skid distance.

Mean skid distance (m) :

⇒ $(m)=\frac{Sum\ of \ the\ skid\ marks }{Number\ of\ skid\ marks}$

⇒ $(m) =\frac{52+52+56+56}{4}$

⇒ $(m) =\frac{216}{4}$

⇒ $(m)=54$ feet.

So the skid distance to be used is 54 feet.
