The number X is placed somewhere between 9 and 10. That's because 9 squared is 81 and 10 squared is 100.
Answer: The answer for x is 6.75. The answer for y 6.75.
Step-by-step explanation:
You are going to mutiple 0.75 x 9 = 6.75. Then, mutiple 0.50 x 9= 4.5. Hope this works.
Answer:
x=1/3 or x=−2

Step-by-step explanation:
Step 1: Add 2 to both sides.
3x^2+5x−2+2=0+2
3x^2+5x=2
Step 2: Since the coefficient of 3x^2 is 3, divide both sides by 3.
3x^2+5x/3=2/3
x^2+5/3x=2/3
Step 3: The coefficient of 5/3x is 5/3. Let b=5/3.
Then we need to add (b/2)^2=25/36 to both sides to complete the square.
Add 25/36 to both sides.
x^2+5/3x+25/36=2/3+25/36
x^2+5/3x+25/36=49/36
Step 4: Factor left side.
(x+5/6)^2=49/36
Step 5: Take square root.
x+5/6=±√49/36
Step 6: Add (-5)/6 to both sides.
x+5/6+ −5/6=
−5/6±√49/36x=−5/6±√49/36x=
1/3 or x=−2
One way is to:
First, multiply 2 by the term inside the parenthesis.
Second, add eleven on both sides.
Third, divide using 4x on both sides.
This will give you your first method.
