we know that
If a ordered pair (x,y) is a solution of the equation, then the ordered pair must satisfy the equation
we have the equation
Let's verify all the cases to determine the solution to the problem.
<u>case A)</u> point
Substitute the values of x and y in the equation
-------> is true
therefore
The point is a solution of the equation
<u>case B)</u> point
Substitute the values of x and y in the equation
-------> is true
therefore
The point is a solution of the equation
<u>case C)</u> point
Substitute the values of x and y in the equation
-------> is not true
therefore
The point is not a solution of the equation
<u>case D)</u> point
Substitute the values of x and y in the equation
-------> is not true
therefore
The point is not a solution of the equation
therefore
<u>the answer is </u>
Answer:
x = 2
Explanation:
2(x+2)-5=3(x-1)
1) Use distributive property (multiply the 2 by x+2 and the 3 by x-1)
2x+4-5=3x-3
2) Combine like terms
2x-1=3x-3
3) Subtract 2x on both sides
-1=x-3
4) Add 3 on both sides
2=x
hope this helps!
(3a^4 * b^-2) * (2a^7 * b^-1)
= 6*a^(4+7)*b^(-2-1)
= 6*a^11*b^-3
You just add the lengths of RS and ST together. In your case RT= 24
