2y-8x=3
2y = 8x -3
y = 4x - 3/2

y = 4x + 3
y = 4x - 3/2
---------------subtract
0 = 0 + 4 1/2

0 can not equal 4 1/2

There's no solution

answer is D.none

Twice last month, Judy Carter rented a car in Fresno, California, and traveled around the Southwest on business. The car rental

ozzi

Answer:

Step-by-step explanation:

Let d = daily fee in dollars

Let +m = milage charge in dollars

In words:

( Cost of rental ) = ( number of days rented )x( daily fee ) + ( miles driven )x( milage fee )

For her first trip:

(1) +240.5+=+4d+%2B+450m+

For her 2nd trip:

(2) +146+=+3d+%2B+200m+

-------------------------

Multiply both sides of (1) by +3+

Multiply both sides of (2) by +4+,

Then subtract (2) from (1)

Consider the following division of polynomials.

bonufazy [111]

A) using long division is one way you can divide polynomials. There are other ways (such as synthetic division) but most prefer the long division. You could use mathematical methods, but long division or synthetic division is the best way to go.

What is the perimeter of the given triangle?

vovikov84 [41]

Answer:

17.2 units

Step-by-step explanation:

You would use the Pythagorean Theorem to solve. The height (a) is 4 units. The base (b) is 6 units.

4^2 + 6^2 = sqrt(52)

This would mean that the hypotenuse is 7.211102550927979 units or 7.2 units (the square root of 4^2 + 6^2).

Now you would need to just add all three sides.
6 + 4 + 7.2 = 17.2 units

Hope that helps! Please mark me brainliest!

Plz help i dont understand

You can search in google if you want for the "inscribed quadrilateral conjecture"

and if you want... I can give you a quick proof of it

hmmm in short, if you inscribe a quadrilateral polygon in a circle
it will have 4 angles

each pair of opposite angles, are "supplementary angles", or they add up to 180°

so.. that said in yours, R+P = 180 and Q+O = 180 as well

you only need Q

so $\bf \measuredangle Q+\measuredangle O=180\qquad 
\begin{cases}
\measuredangle Q=2x+4\\\\
\measuredangle O=2x
\end{cases}\implies (2x+4)+(2x)=180$

solve for "x"

how big is Q? well, 2x + 4 :)
