Answer:
(-4, 0)
Step-by-step explanation:
x-2 means ur gonna take coordinate A and move it back 2 places along the x axis, (-4,-2) and then y+2 means ur gonna go up to places alomg the y axis which brings coordinate A' to (-4,0)
If < A and then m< A + m/B = 90°, then D. Definition of Complementary Angles
<h3>What is a complementary angle?</h3>
When the sum of two angles is 90°, the angles are said to be complementary. In other words, if two angles add up to form a right angle, they are called complementary angles. The two angles are said to complement each other in this context.
Supplementary angles are two angles that add up to 180 degrees, whereas complementary angles are two angles that add up to 90 degrees.
An angle measuring 72 degrees has a complement of 18 degrees.
Therefore, based on the information given, the correct option is D.

Radical Equation:
1. Isolate the radical expression.
2. Square both sides of the equation: If x = y then x2 = y2.
3. Once the radical is removed, solve for the unknown.
4. Check all answers.
Another way of saying it:
1. Isolate the radical expression involving the variable. ...
2. Raise both sides of the equation to the index of the radical.
3. If there is still a radical equation, repeat steps 1 and 2; otherwise, solve the resulting equation and check the answer in the original equation.
6.54 because the units are the same so you look to see which one has the most numbers after the decimal
Step-by-step explanation:
b. 3x + 7y = 7
b. 3x + 7y = 75x − 7y = −63
Both the equations have common coordinate point (-7,4)
3x + 7y = 7
LHS = 3(-4)+7(4)= -21+28= 7. RHS = 7
Therefore, the equation satisfies.
5x − 7y = −63
LHS = 5(-7)-7(4) = -35-28= -63. RHS = -63
Therefore, the equation satisfies.
