Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(2,−4)
Equation Form: x= 2, y = −4
Step-by-step explanation:
I did the math
They are the same because the distance formula depends on a right triangle relationship between x and y, where as the right triangle has the same relationship with x being one leg of the right triangle and y the other leg of the right triangle
Answer:
D dilation and reflection
Step-by-step explanation:
Rotation, reflection, and translation are "rigid" transformations, so will always result in congruent figures.
Dilation is a transformation that changes size, so will result in figures that are similar, but not congruent. Any rigid transformation performed with dilation will still result in a similar figure.
Answer:
C
Step-by-step explanation:
the domain would be all positive real numbers, including zero
Answer:
pi/2
Step-by-step explanation:
Arccos(tan(0))
Arccos( 0) since tan(0)=0
Arccos(0)=pi/2 since cos(pi/2)=0 and the restricted domain of cosine is [0,pi].
