Answer:
D, the bottom right
Step-by-step explanation:
A dilation by a factor of 3 would have values 3 times larger. So the original which has side lengths 2, 6, and 3 would become
2*3 = 6
6*6 = 36
3*6 = 18
The figure which has these measurement is D or the bottom right.
Answer:
Focus of a Parabola. A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix. The focus lies on the axis of symmetry of the parabola.

Answer:
$6
Step-by-step explanation:
there was 11 total and 5 went into the soda and 6 went into the pizza so it's 6.
A- the grams of copper is total which is 128 grams.*** b- is the total amount of percent of copper which is 71.76%+9.37
9514 1404 393
Answer:
- B
- B
- a) f(3y-1) = 24y -17; b) f(-7/4) = -23
Step-by-step explanation:
1. Any mapping requiring segment lengths to be congruent will require a "rigid" transformation, some combination of rotation, reflection, and translation.
If the transformation is not one of those, then segment lengths may change. The transformation we usually study that is not a rigid transformation is <em>dilation</em>. It preserves angles and slopes, but not segment lengths.
Of the choices listed, only choice B does not involve congruent segments.
__
2. In line with the discussion above, the dilation will preserve the slope of KM so that it is the same as the slope of K'M'. This is described by choice B.
__
3.
a) Finish simplifying the equation already written.
f(3y -1) = 8(3y -1) -9 = 24y -8 -9
f(3y -1) = 24y -17
b) f(x) = -23
8x -9 = -23
8x = -14 . . . . . . add 9
x = -14/8 = -7/4 . . . . divide by 8, reduce the fraction
x = -7/4 = -1.75
