Given:

Selling price of a machine = 7000/-

Gross loss = 20%.

To find:

The cost and gross loss.

Solution:

Let x be the cost of machine.

According to the question,

x-20\%\text{ of }x=7000

x-\dfrac{20}{100}x=7000

x-0.2x=7000

0.8x=7000

Divide both sides by 0.8.

x=\dfrac{7000}{0.8}

x=8750

So, the cost of the machine is 8750/-.

Now,

\text{Gross Loss}=\text{Cost}-\text{Selling price}

\text{Gross Loss}=8750-7000

\text{Gross Loss}=1750

Therefore, the gross loss is 1750/-.

At which x value will f(x)=3x+3 exceed g(x)=3x+10
Anvisha [2.4K]
We write an inequality:

f(x) > g(x)

3^x + 3 > 3x + 10

3^x > 3x + 7

This equation cannot be solved using trivial methods found in high-school classes, so we resort to graphical examination.  3x+7 is a linear function while 3^x is an exponential one (with limit zero as x approaches - \infty).  We see that 3^x = 3x+7 at approximately x=2.4 and x=-2.3.

Indeed, using a computer algebra system such as the ones on modern TI calculators and on many internet sites gives equality at x=2.42, -2.31.  By observing our graph, we see that f(x) > g(x) when x > 2.42 or x < -2.31.

Complete the following ordered pairs.<br> Y=-7x+8<br> (0,__)<br> (7,__)<br> (__,36)
Sonbull [250]

Answer:

Answers are in bold in explanation

Step-by-step explanation:

We are given the equation:

y = -7x + 8

The first x value is 0

y = -7(0) + 8

y = 8

(0, 8)

The next x value is 7

y = -7(7) + 8

y = -41

(7, -41)

Now we are given the Y value instead of X, so we do this:

36 = -7x + 8

Subtract 8 on both sides to leave -7x alone

28 = -7x

Divide by -7 on both sides to isolate x

-4 = x

(-4, 36)
