Answer:

Solution: (2, 2)

Step-by-step explanation:

The first equation describes a line with a y-intercept of 3 and a (downward) slope of -1/2. That is, it has a "rise" of -1 for a "run" of 2.

The second equation describes a line with a y-intercept of -2 and an (upward) slope of 2. That is, it has a "rise" of 2 for a "run" of 1.

These two lines meet at the point (2, 2), which is the solution to the set of equation. Those are the values of x and y that satisfy both equations.

G=x-c/x. for x<br><br>how do yoy make this an equation for x? help

zzz [600]

1.
$\displaystyle \text{if }\quad G=x- \frac{C}{x} \\\\$

$x \neq 0$

Multiply both sides by x:

$\displaystyle Gx=x\bigg(x- \frac{C}{x}\bigg )\\\\Gx=x^2-C$

Subtract from both sides Gx:
$Gx-Gx=x^2-C-Gx\\x^2-Gx-C=0$

Then solve this equation:

$\displaystyle x^2-Gx-C=0\\\\x_{1,2}= \frac{G\pm \sqrt{G^2+4C} }{2}$

2.
$\displaystyle\text{if}\quad G= \frac{x-C}{x}$

$x \neq 0$

Multiply both sides by x:

$Gx=x-C$

Subtract from both sides Gx:

$x-C-Gx=0$

Then solve this equation:

$\displaystyle x-Gx-C=0\\x(1-G)=C\\x= \frac{C}{1-G}$

The wheels on a car have a diameter of 28 inches. How many full revolutions will the wheels need to make to travel 200 feet?

rodikova [14]

Here we're interested in the circumference: C = pi*d. In this case C = 3.14*(28 inches) = 88 inches.

Now divide this 88 inches into 200 feet to get the # of revolutions ncessary to travel 200 feet.

200 feet 12 in
------------ * --------- = 2400 inches
1 1 ft

2400 inches
----------------------- = 27.2 revolutions (answer)
[ 88 inches/ rev ]
