Answer:

Step-by-step explanation:

y - 5 > 2x - 10 \\\ y > 2x - 10 + 5 \\\ y > 2x - 5

If x = 0:

y > 2 × 0 - 5

y > - 5

If x = 3:

y > 2 × 1 - 5

y > 1

The coordenates (3, 1) and (0, -5) are not included.

Alternative A

I hope I helped you.

Answer:

Graph B

Step-by-step explanation:

we have to graph  y - 5 > 2x - 10

Before graphing it we will simplify the inequality first

y - 5 > 2x -10

y > 2x + 5 - 10

y > 2x - 5

In this inequality sign of greater than is used so  all the solution of the inequality will be above the line.

Since there is no sign of equality so line will be denoted by dotted lines.

By these facts graph B will be our desired answer.

Jamil finds that he reads 1/5 of his 115-page book in 1/4 hour
Nadya [2.5K]

Answer:

He will read 92 pages in an hour going by the current rate at which he reads

Step-by-step explanation:

The complete question is as follows;

Jamil found that he reads 1/5 of his 115 - page book in 1/4 of an hour. At this rate how many pages does he read in an hour

We proceed as follows;

If he reads 1/5 of 115 in 1/4 hour

1/5 of 115 pages refer to 1/5 * 115 = 23 pages

This means that he reads 23 pages in quarter of an hour

So in an hours the number of pages he will read will be 23 * 4 = 92 pages

A culture of bacteria that initially contained 2000 bacteria has a count of 18000 after 2 hrs. Determine the function that expre
melomori [17]

Answer:

y= 8000x + 2000

Step-by-step explanation:

to find the formula we can use the points given in the question:

the slope:

to get the slope we can take the 2 points, (0,2000) and (2,18000) where x values are time and y values are bacteria

now using slope-intercept form we can get \frac{18000-2000}{2-0} which gives a slope of 8000 meaning for each hour there are 8000 new bacteria

intercept:

since we start with 2000 bacteria we know this is the y intercept so when x is 0

formula:

y=8000x + 2000
