Assume there are 100 million passenger cars in the. United States and that the average fuel consumption is. 20 mi/gal of gasolin

Anastasy [175]

10,000 miles : 20 mi/gal = 500 gal
10,000 miles : 25 mi/gal = 400 gal
500 - 400 = 100 gal ( saved per year )
100 x 100,000,000 = 10,000,000,000
Answer: 10 billion gallons of fuel would be saved if the average fuel consumption mi/gal was increased to 25.

Find the points of intersection of the equation: xy=2 and x+y =4

Blizzard [7]

Answer: $\Large\boxed{(2+\sqrt{2},~2-\sqrt{x} )~~and~~ (2-\sqrt{2},~2+\sqrt{x} )}$

Step-by-step explanation:

<u>Given the system of equations</u>

$1)~xy=2$

$2)~x+y=4$

<u>Divide x on both sides of the 1) equation</u>

$xy=2$

$xy\div x=2\div x$

$y=\dfrac{2}{x}$

<u>Current system</u>

$1)~y=\dfrac{2}{x}$

$2)~x+y=4$

<u>Substitute the 1) equation into the 2) equation</u>

$x+(\dfrac{2}{x} )=4$

<u>Multiply x on both sides</u>

$x\times x+\dfrac{2}{x}\times x=4\times x$

$x^2+2=4x$

<u>Subtract 4x on both sides</u>

$x^2+2-4x=4x-4x$

$x^2-4x+2=0$

<u>Use the quadratic formula to solve for the x value</u>

$x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(1)(2)} }{2(1)}$

$x=2\pm\sqrt{2}$

<u>Substitute the x value into one of the equations to find the y value</u>

$xy=2$

$(2+\sqrt{2} )y=2$

$y=2-\sqrt{2}$

$OR$

$xy=2$

$(2-\sqrt{2} )y=2$

$y=2+\sqrt{2}$

Therefore, the points of intersection are

$\Large\boxed{(2+\sqrt{2},~2-\sqrt{x} )~~and~~ (2-\sqrt{2},~2+\sqrt{x} )}$

Hope this helps!! :)
