This table shows the relationship of the total number of pieces of fruit to the number of bananas.

ddd [48]

Given:

The table that shows the relationship of the total number of pieces of fruit to the number of bananas.

To find:

Why is $\dfrac{6}{5}$ not equivalent to $\dfrac{3}{2}$ .

Solution:

If a, b, c are real numbers, then

$\dfrac{a}{b}=\dfrac{a\times c}{b\times c}$

The given fraction is $\dfrac{3}{2}$ . It can be written as:

$\dfrac{3\times 2}{2\times 2}=\dfrac{6}{4}$

The number 3 is multiplied by 2 to get 6. So, the 2 should also be multiplied by 2. The ratio should be $\dfrac{6}{4}$ , not $\dfrac{6}{5}$ .

Therefore, the correct option is A.

What is the solution to the inequality

Dvinal [7]

Answer:

p > 5 and p <-8

Step-by-step explanation:

To solve this, you first need to isolate p.

First add 6 on both sides of the equation:

$-6 + |2p+3| >7\\\\(+6) -6 + |2p+3| >7 +6\\\\2p + 3 > 13$

Then subtract 3 from both sides of the equation.

$2p+3-3>13-3\\\\2p > 10\\$

The divide both sides by 2.

$\dfrac{2p}{2}>\dfrac{10}{2}\\\\p>5$

Another solution is possible because of the absolute value.

If $|2p+3|>13$

Then $|2p+3|$

<em>Thus we can solve the second solution:</em>

$|2p+3|$

$2p+3$

Isolate P again by subtracting both sides by 3

$2p+3-3$

$2p$

Then divide both sides by 2:

$\dfrac{2p}{2}$

$p$

The answer ............

suter [353]

Answer:

f^-1(x) = ( x + 6 )/4

Step-by-step explanation:

f(x) is the same as...y = 4x + 6....and then try to make x the subject of formula

y + 6 = 4x

x = (y + 6)/4....then when writing f^-1(x)...replace y with x

f^-1(x) = ( x + 6 )/4
