I would have to say that it is the 3rd answer choice due to the right angle that is formed between line C and line A.
Answer:
3/2
Step-by-step explanation:
Use the slope formula:
m = (y2-y1)/(x2-x1)
m = (5-(-4))/(2-(-4))
m = 9/6
m = 3/2
The number π produces a rational number (117/35) when added to 1/5
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero
π = 22/7, hence:
π + 1/5 = 22/7 + 1/5 = 117/35
The number π produces a rational number (117/35) when added to 1/5

Alright this equation has two big steps. First we need to find the price after it was marked up, then we need to take that number and find the discounted price.
To find the cost after a percent of it was added, we just need to multiply the two together and add.

23.50

(we divide by 100 to get the number out of a percent)

Ok now that we have the number after the price increase, we now need to find the final answer after a discount of

(do the exact same idea as above but switch the sign)

Answer:
Y= 5
Step-by-step explanation:
14+13Y=20Y-21
-13y -13y
14=7y-21
+21 +21
35/7=7y/7
y=5
