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.
Answer:
Stephanie brought the 20 chocolate for $50
Step-by-step explanation:
If she have $60 and only have $10 left that would me that the chocolate are $50
-17(y - 2) = -17y + 64
Distribute the -17
-17y + 34 = -17y + 64
Add 17y to both sides
34 = 64
Once the variables cancel, and you end up with a FALSE statement, this means there are NO SOLUTIONS.
You can set it up as an equation:
29.95x + 2x
then plug in x = 7.
I'm not sure how this really relates to the distributive property though.
Answer:
79°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral (4 sided figure) IS 360.
Take 360 - (101 + 121 + 59)
360 - 281 = 79
