I think of a number, multiply it by 4, subtract 6 and then divide by 5. If the answer is 10, what is the original number?

1 answer:

7 0

To find the answer do the opposite of the operations from the last number.

10•5=50
50+6=56
56/4= 14

Therefore the original number is 14.

Convert the fraction 7 24 into a repeating decimal.

goldenfox [79]

$\dfrac7{24}=\dfrac6{24}+\dfrac1{24}=\dfrac14+\dfrac1{24}$

$\dfrac1{24}=\dfrac1{8\time3}=\dfrac a8+\dfrac b3=\dfrac{3a+8b}{24}$
$\implies3a+8b=1$

We can choose $a=-1$ and $b=\dfrac12$ , so that

$\dfrac1{24}=-\dfrac18+\dfrac16$

Recalling that $\dfrac13=0.333\ldots$ , it follows that $\dfrac16=0.166\ldots$ . So,

$\dfrac1{24}=0.125+0.166\ldots=0.04166\ldots$
$\implies\dfrac7{24}=0.25+0.4166\ldots=0.29166\ldots$

The graph of F(x) can be compressrd vertically and shifted to the right to produce the graph of G(x). If F(x) = x^3, which of th

rosijanka [135]

It is option A. A vertical compression means that the function is only a "fraction" of its original height, hence the fractional coefficient. 

REMEMBER, movement along the x-axis is always the OPPOSITE of what you think. So left = + and right = -

So (x-6) actually means a shift 6 units to the right. (NOT left like you would naturally think)

Digiron [165]

Answer:

associative

combining

commutative

Step-by-step explanation:

1. associative property of addition since the grouping is changed

2. combining like terms since it's the addition of 4 and 6

3. commutative property of addition since it's a change of order
