Answer:

Step-by-step explanation:

As we can see;

10 * ( a + b ) / 9 * ( x - y ) ⇒ 10a + 10b / 9x - 9y

This concludes that the top part of this equation is multiplied by 10 and the bottom by 9. To derive the solution, let us do the same with 3 / 5;

10a + 10b / 9x - 9y = 3 * 10 / 5 * 9

And simplify, to recieve;

10a + 10b / 9x - 9y = 30 / 45 = 6 / 9 = 2 / 3,

<em>Answer: 10a + 10b / 9x - 9y = 2 / 3</em>

A coin is tossed 4 times. Which of the following represents the probability of the coin landing on heads all 4 times?

galben [10]

Answer:

C.1/16

Step-by-step explanation:

When a coin is tossed 4 times, the number of outcomes are:

2^4 = 16

So,

From the outcomes, only one outcome will be when there will be all heads

So, the probability will be:

One out of the 16 outcomes

Hence, the probability of a coin landing on heads all 4 times is:

C.1/16

Answer:

a). 8(x + a)

b). 8(h + 2x)

Step-by-step explanation:

a). Given function is, f(x) = 8x²

For x = a,

f(a) = 8a²

Now substitute these values in the expression,

$\frac{f(x)-f(a)}{x-a}$ = $\frac{8x^2-8a^2}{x-a}$

= $\frac{8(x^2-a^2)}{(x-a)}$

= $\frac{8(x-a)(x+a)}{(x-a)}$

= 8(x + a)

b). $\frac{f(x+h)-f(x)}{h}$ = $\frac{8(x+h)^2-8x^2}{h}$

= $\frac{8(x^2+h^2+2xh)-8x^2}{h}$

= $\frac{8x^2+8h^2+16xh-8x^2}{h}$

= (8h + 16x)

= 8(h + 2x)
