Answer: The slope of the line is -2
Step-by-step explanation:
We can use the formula
to solve to for this

Answer:
A
Step-by-step explanation:
9 items at $50 each would be 9 × $50 = $450, which is more money than he has.
The first equation uses the first and second coupons. the coupon (1-y)40 will take y% off of the dress pants so the answer is 40(1-y)
Answer:
B) n=-2
Step-by-step explanation:
First, distribute.
7(1+4n)-5=-38+8n
7+28n-5=-38+8n
Combine like terms.
2+28n=-38+8n
To make solving the equation easier, subtract 8n first, so there isn't a negative variable.
2+28n=-38+8n
<u>-8n -8n</u>
2+20n=-38
Subtract 2 on both sides.
2+20n=-38
<u>-2 -2</u>
20n=-40
Divide by 20 on both sides.
20n=-40
<u>/20 /20</u>
n=-2
Hope this helps!! Have a wonderful day :3
<u>Answer-</u>
An angle is labeled with either one capital letter or three capital letters
<u>Solution-</u>
<em>Point-</em>
As a point is 0 dimensional, so you just need 1 point to define a point.
<em>Line- </em>
As a line is 1 dimensional,so you need 2 points to define a line.
<em>Plane-</em>
A plane is 2 0r 3 dimensional, so you need 3 points to define a plane.
<em>Angle-</em>
An angle measures the amount of turn. An angles is labeled with a single letter at the vertex, as long as it is perfectly clear that there is only one angle at this vertex. Otherwise, it is named according to the intersecting lines with 3 letters.
