Answer:
A.
Step-by-step explanation:
We are given the two points (2,7) and (4,-1). In order to determine the linear equation, we need to find the slope and the y-intercept. First, find the slope <em>m.</em> Let (2,7) be x1 and y1, and let (4,-1) be x2 and y2:
Thus, the slope is -4.
Now, to find the y-intercept, we can use the point-slope form. Recall that the point slope form is:
Where (x1, y1) is a coordinate pair and m is the slope.
Use either of the two coordinate pair. I'm going to use (2,7). Substitute them for x1 and y1, respectively:
This is also slope-intercept form. The answer is A.
so, 7 is neutral anything past 7 is considered basic.
answer: <em>a water and ammonia solution with a pH of 11 (very basic).</em>
<em />any number under 7 is acidic and of course there are different degrees of acidic just like there are different degrees of basicity.
______________________________________________________________
- stomach's digestive juices, would be considered very acidic
-apple juice is also acidic but not as acidic like stomach juices.
- grape juice, is becoming less acidic.

Hopefully this helped and good luck.
Answer:
$1.99 is more expensive.
Step-by-step explanation:
Given:
One type of lace edging cost $0.80 per foot
Another type of lace edging cost $1`.99 per foot.
We need to find which is more expensive.
In $0.88 where one's place is 0.
In $1.99 where one's place is 1.
By comparing the one's place obviously $1.99 more expensive.
Hope you will understand the concept.
Thank you.
The answer is 3. If you set it up in a T table and label x as the number of hours and y as the number of rows. Then use rise over run (y over x) the fractions simplify to 3 over 1.
11 is the biggest and the 22
