If 1/p+q=r and p≠-q, what is p in terms of r and q?

bekas [8.4K]

p = (1/r) - q

In order to find this, follow the order of operations to get the answer.

1/p+q = r ----> Multiply both sides by p+q

1 = r(p + q) -----> Divide by r

1/r = p + q -----> subtract q from both sides

(1/r) - q = p

Relationship B has a greater rate than Relationship A. This graph represents Relationship A.

tester [92]

Answer:

Rate in relationship A = (6 - 3)/(8 - 4) = 3/4 = 0.75

For Table A: Rate = (3 - 1.2)/(5 - 2) = 1.8/3 = 0.6

For table B: Rate = (3.5 - 1.4)/(5 - 2) = 2.1/3 = 0.7

For table C: Rate = (4 - 1.6)/(5 - 2) = 2.4/3 = 0.8

For table D: Rate = (2 - 1.5)/(4 - 3) = 0.5/1 = 0.5

Therefore, the correct answer is option C.

The population of a culture of cells grows according to the function P(t)= 90t/ t + 1, where t> or =0 is measured in weeks. C

butalik [34]

Answer:

The average rate of change is $\frac{18}{5}$

Step-by-step explanation:

Given function that shows the population of a culture of cells,

$P(t)=\frac{90t}{t+1}------(1)$

Where, t represents the number of weeks.

Thus, the average rate of change in the population over the interval [0,24],

$m=\frac{P(24)-P(0)}{24-0}$

From equation (1),

$=\frac{\frac{90\times 24}{24+1}-\frac{90\times 0}{0+1}}{24}$

$=\frac{\frac{2160}{25}-\frac{0+1}{0}}{24}$

$=\frac{2160}{25\times 24}$

$=\frac{2160}{600}$

$=\frac{18}{5}$

if you have the numbers 1,4,5 and 8 in in a box and Kelly randomly chose one tile and placed it back and chose another tile what

chubhunter [2.5K]

hello

to solve this question, we need to use know the number of possible outcomes

$\begin{gathered} \text{probability = }\frac{nX}{nS} \\ S=\text{ number of possible outcomes} \\ X=\text{ number of events} \end{gathered}$

let's find the number of possible outcomes

we have four tiles numbered 1, 4, 5 and 8

possible outcomes are

$undefined$
