To show that the ratio $\frac{y}{x}$ is not constant for the function $y=a-14$ we only need to evaluate this function at 2 points and then show that the ratio is not the same for those two points. Note that here $a$ represents $x$ .

To find the counter examples here, I will use the values $a=20$ and $a=28$ . For $a = 20$ , the equation tells us that the output is

$y=20-14=6$ . For this value of $a$ the point is point is $(20,6)$ . The ratio $\frac{y}{x} =\frac{6}{20}$ . For the $a=28$ , $y=28-14=14$ . For this value of $a$ the point is $(28,14)$ . The ratio $\frac{y}{x} =\frac{14}{28} =\frac{1}{2}$ . Clearly this ratio is not constant for all ordered pairs.

What is the slope of the trend line drawn into the scatter plot?

mario62 [17]

Formula for slope: $\frac{y2-y1}{x2-x1}$
Plug in points given: $\frac{136-27}{13-2} 
= \frac{109}{11} = 9.9 = 9 \frac{9}{10} (Rounded) 
$
Slope: $9.9 = 9 \frac{9}{10}$

What is 142.34 divided by 24? And show work

max2010maxim [7]

142.34 divide by 24 will give you the answer of 593.083 ----> 

24 x 5 will equal 120 which is close to 142 then subtract 120 by 142 which will give you 22 then bring down the 3 and you will have 223 which 24 x 9 will give you 216 then subtract 223 -216 which gives you 74 then 24 x 3 = 72 then you add a decimal then a zero which is 20 then add another zero which is 200 then multiply 24 by 8 which is 192 and then subtract 200 by 192 and get 72 and then your answer will keep on going.

What does the word “flip” tell you to do in “keep change flip” for dividing fractions a) change the place of the numbers numerat

mars1129 [50]

Answer:

b) change the places of the numbers in the numerator and the denominator for the second fraction

Step-by-step explanation:

In the phrase "keep change flip":

You "keep" the first fraction.

"Change" the division sign into a multiplication sign.

"Flip" (or switch) the places of the numerator and denominator in the second fraction.

Example:
