You can use mental math for this equation because it is fairly easy.

You would use mental math by looking at the equation and thinking, “What is 1/75 times 1/2?” Since you want to find out what w is. Since this is mental math, you would know the answer directly, it is 1/150.

Meaning w = 1/150

vovangra [49]

Answer:

26.25 minutes

Step-by-step explanation:

Given that :

Number of pages (p) read by Elias can be modeled by the function ;

p = 45m + 18

Where P = Number of pages ; m = number of minutes

Number of minutes it will take to read a total of 39 pages

p = 4/5m + 18

39 = 4/5m + 18

39 - 18 = 4/5m

21 = 4/5m

4m = 21 * 5

4m = 105

m = 105 / 4

m = 26.25

Hey can you please help me posted picture of question

A relation can be a function if an x value is not paired with more than y-values.
The x and y values are flipped when finding an inverse.

So, if in the inverse function a y value is paired with more than one x values, this will mean that in the function an x-value was paired with more than one y-values.

Looking at the graph we can say that no y-value in the inverse is paired with more than one x values, so the original relation would be a function.

So the answer is TRUE
