Answer: they are parallel
Step-by-step explanation:
find slope of line m:
Use y2-y1/x2-x1
your m equation --> 9-15/10-3 which makes the slope of m = -6/7
find slope of line n:
Use y2-y1/x2-x1
your n equation --> 3-9/9-2 which makes the slope of n = -6/7
The slopes are the same, therefore line m and line n are parallel.
The correct answer is about two hours. Hope this helps.
Answer:
Its a i just took the test
Step-by-step explanation:
Hello! The sale price is $119, and the camera has been discounted by 15%. Even with the discount, 85% of the original price is still paid. 100% makes the whole price and 100 - 15 is 85. To find the original price of the camera, we can write and solve a proportion. Set it up like this:
119/x = 85/100
This is because 119 is part of the whole and is 85% of the original price. Remember that 85% is part of 100%. Let's cross multiply. 119 * 100 is 11,900. 85 * x is 85x. That makes 11,900 = 85x. Now, divide each side by 85 to isolate the x. 85x/85 cancels out. 11,900/85 is 140. Let's check that number and see if it works. 140 * 85% (0.85) is 119. There. x = 140. The original price of the camera was $140.
The like terms are 12 and 5, so you have to subtract 5 from both sides.
12 < x + 5
-5. -5
7 < x
We can just switch it around so x is in the left side.
x > 7
