bear in mind that the degree of a polynomial comes from the highest degree of any of its terms, and the degree of a term is the sum of all exponents in the variables.
Dilation refers to a non rigid motion where a figure is transform and its image has the same form but a different size measure.Dilation is define by the rule
(x,y)-- (kx, ky) where
k represents the scale factor.
In this exercise is given that a quadrilateral with vertices
K'(2,1),
L'(-2,3),
M'(-3,-4) and
N'(3,-5) was dilated by a scale factor of

, and it is asked to find the vertices of the pre-image of the quadrilateral.
Image Pre-ImageK'(2,1) ---- (2×2,1×2) ---- K(4,2)
L'(-2,3) --- (-2×2,3×2) --- L(-4,6)
M'(-3,-4) -- (-3
×2,-4×2) -- M(-6,-8)
N'(3,-5) --- (3×2,-5×2) --- N(6,-10)
The coordinates which represent the vertices of the quadrilateral's pre-image are K(4,2), L(-4,6), M(-6,-8), and N(6,-10) or in other words letter C from the given choices.
All real numbers are solutions
Answer:
(1,5)
Step-by-step explanation:
First, arrange the data from lowest to highest
19, 20, 21, 22, 23, 24, 25, 27, 29, 30, 33
Next, find the media or the middle data.
The median is 24.
<span>19, 20, 21, 22, 23, 24 (median), 25, 27, 29, 30, 33
</span>
Lastly, look at the data below the median and find the middle of those data. If it's between two numbers, choose the lower number. That's the first quartile.
The first quartile is 21.
19, 20, 21(Q1), 22, 23, 24 (median)<span>, 25, 27, 29, 30, 33</span>
