Hi I have a question in math similarity and Prove A pre-image includes a line segment with a length of X units and a slope of M units. The pre-emergent is dilated by a scale factor of N. The length of the corresponding line segment in the image …….is units. The slope of the corresponding line segment in the image is………

The first is nx and the second one is m

Slope: We know that slope is the ratio of change in y-value and change in x-value so dilation do not change slope of any line. So, after dilation, m>m

Length of line: we know that a dilation has the effect of stretching or shrinking the line segment by the factor of m units. We are given the length of line =x. So, it's length will become n * x = nx

lmk if im wrong :)

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
