Answer:
Step-by-step explanation:
x^2-1=0
Add 1 to both sides of the equation.
x^2=
1
Take the square root of both sides of the equation to eliminate the exponent on the left side.
x
=
±
√
1
Any root of 1 is x
=
±
1
First, use the positive value of the ±
to find the first solution.
x=
1
Next, use the negative value of the ±
to find the second solution.
x
=
−
1
The complete solution is the result of both the positive and negative portions of the solution.
x
=
1

Answer:
49% of 49 is 24.01
Step-by-step explanation:
When rotating 90 degrees counterclockwise about the origin, the original coordinates are changed according to the rule (-y, x). Therefore, we take the original coordinates and switch them up accordingly to the rule listed above. When we do so, we get the coordinates Z'(4,0); J'(2,-5); L'(3,0). Hope this helps and have a phenomenal day!
Eithet 330x4 or 330 divide 4 so it is either= 1320 or 82.5 hope this helps
