Answer:
x = -2 ±sqrt( 19)
Step-by-step explanation:
x^2 + 4x = 15
Take the coefficient of x
4
Divide by 2
4/2 =2
Square it
2^2 = 4
Add it to each side
x^2 + 4x+4 = 15+4
(x+2)^2 = 19
Take the square root of each side
sqrt( (x+2)^2) =±sqrt( 19)
x+2 = ±sqrt( 19)
Subtract 2 from each side
x+2-2 = -2 ±sqrt( 19)
x = -2 ±sqrt( 19)
Answer:
Answer: A. G(x)= ax=y= - f(x) is flip over x-axis. Therefore, f(x) =14x would become f(x) =-14x. Therefore, final transformed function f(x)=-14x is vertically stretch by a factor of 14 and flip over the x-axis.
Step-by-step explanation:
Answer:
Images are neither similar nor congruent.
Coordinates of (-3,2) when transformed are (-6, 8).
Step-by-step explanation:
In the transformation we are multiplying the coordinates by two different numbers (2 for x, 4 for y ); therefore the transformed figure can neither be similar nor congruent.
This is because a transformation that results in a congruent figure must of of the form
—this is just shifting the figure.
The transformation that results in a similar figure must be of the form
or
—this is just scaling the figure.
Since the transformation
is neither a congruent transformation nor a similar transformation ,the resulting figure in neither similar nor congruent.
The point (-3, 2) transforms to
