The square root of 69 is 8.30.because 8.30*8.30 is 69
Answer:
False; they are equal.
Step-by-step explanation:
The equation is x + 20 > 4x - 1.
First, do the opposite of -1 and add one to the other side while -1+1 cancels out. Now it's x+21 > 4x. Now subtract x from both sides. Positive x minus negative x cancels out and 4x minus x or 1x is 3x. Now you're left with 21> 3x. Now do the inverse operation of multiplication and divide both sides by 3. Now the 3x over 3 cancels out and 21 divided by 3 is 7. So x is 7. If you substitute it in. It will be 7+20 which is 27 which is great than 4(7)-1 which is 28-1. 28-1 is 27. So, the equation is false. They are equal.
Answer:
- 0.25
Step-by-step explanation:
Sine -1/4 is a fraction, you can think of it as quarters in this case. there are 4 quarters in a dollar. 1/4 = 25/100.
we have
we know that
If the point is an equation solution, it must satisfy the equation.
<u>case a</u>) 
Substitute the values of x and y in the equation
-------> the point is not solution of the equation
<u>case b</u>) 
Substitute the values of x and y in the equation
-------> the point is solution of the equation
<u>case c</u>) 
Substitute the values of x and y in the equation
-------> the point is not solution of the equation
<u>case d</u>) 
Substitute the values of x and y in the equation
-------> the point is not solution of the equation
therefore
<u>the answer is</u>
The point is solution of the equation
