When solving for y your going to get y=3-2x and then graphing i’ll put a picture
Okay, so your scale rectangle has a length of l = 8.2 cm. The actual triangle has a length of L = 41 cm. What is the scale factor? You find out by dividing the scale rectangle l from the actual rectangle L.
41 cm / 8.2 cm = 5
The scale factor is 5. That means the actual rectangle is exactly 5 times bigger than the scale rectangle. Now finding the width is easy! If the width of the scale rectangle is 2.1 cm and the scale factor is 5, you just multiply them together!
2.1 cmx 5 = 10.5 cm
The width of the actual rectangle is 10.5 cm! Hope that helps!
Answer:
A
Step-by-step explanation:
You can eliminate B and D because it’s using 
, but the question is asking 
. So it’s either A or C. They are both written correctly, but out of the two, A is correct because just that x ≠ 
part of it is what makes it true.
The reason being is that the only thing that won’t make 
true is when the denominator equals 0, because anything divided by 0 is undefined. So, when you plug for x in the denominator you get: 
. The 
part just turns into 7, and 7 - 7 is 0. So you don’t want x to equal .
<u>So the answer is A:</u> 
, 
±
There you go my friend!
I hope you understand and that this helps with your question! :)
