Question 1 (4 points) (02.02) Line segment CD is shown on a coordinate grid: A coordinate plane is shown. Line segment CD has endpoints 1 comma 2 and 1 comma negative 1. The line segment is reflected about the y-axis to form C′D′. Which statement describes C′D′? (4 points) Question 1 options: 1) C′D′ is perpendicular to CD. 2) C′D′ is half the length of CD. 3) C′D′ is greater than twice the length of CD. 4) C′D′ and CD are equal in length.

10 you would take 50/ .2

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
