B is the correct answer. The actual prices for Awesome Autos are higher than Cool Cars, but they started the graph at a higher price (not zero) so that their bars would appear lower.

Please help

ASHA 777 [7]

Answer:

(-6,4)

Step-by-step explanation:

The equations are:

$x^2+4y^2=100\\4y-x^2=-20$

Solving for x^2 of the 2nd equation and putting that in place of x^2 in the 2nd equation we have:

$4y-x^2=-20\\x^2=4y+20\\-------\\x^2+4y^2=100\\4y+20+4y^2=100$

Now we can solve for y:

$4y+20+4y^2=100\\4y^2+4y-80=0\\y^2+y-20=0\\(y+5)(y-4)=0\\y=4,-5$

So plugging in y = 4 into an equation and solving for x, we have:

$x^2=4y+20\\x=+-\sqrt{4y+20} \\x=+-\sqrt{4(4)+20} \\x=+-\sqrt{36} \\x=6,-6$

So y = 4 corresponds to x = 6 & x = -6

The pairs would be

(6,4) & (-6,4)

we see that (-6,4) falls in the 2nd quadrant, thus this is the solution we are looking for.

M= y2-y1/x2-x1
M= 1-5/3-2
M= -4/1
M=-4

The number would stay the same because, for example, 6 - 0 can't be 0 so it would be 6.

zimovet [89]

You have to choose $6$ members from the group of $35$ people. So there are $\binom{35}{6}$ ways to do it.
