The answer is 1 1/4 because 1/2 is equal to 2/4 and 2/4 + 3/4 = 5/4. 5/4 is equal to 1 1/4. Hope this helps!
Answer:
a = 
x = 27y
Step-by-step explanation:
Order of Operations: BPEMDAS
<u>Question 1</u>
Step 1: Write out discriminant
d = b² - 4ac
Step 2: Subtract b² on both sides
d - b² = -4ac
Step 3: Divide both sides by -1
b² - d = 4ac
Step 4: Divide both sides by 4c
a = 
<u>Question 2</u>
Step 1: Write out equation
2/3(x - 18y) = 6y
Step 2: Distribute parenthesis
2/3x - 12y = 6y
Step 3: Isolate <em>x </em>by adding 12y on both sides
2/3x = 18y
Step 4: Divide both sides by 2/3
x = 27y
What?? I am very sorry, but this is confusing.
The 3 option
(3,9), (-7,1), (6,12), (-3, -9)
Answer:Thus, (-3)-4 = 1/(-3)4.
Step-by-step explanation:
Negative exponents have the following property: n-m = 1/nm OR 1/n-m = nm
So for (-3)-4 , n= -3 and -m= -4 (or m= 4).
Thus, (-3)-4 = 1/(-3)4.
