At 4: 00 a. m. , the temperature was -9 . at noon , the temperature was 18 . what was the change in

The difference in temperature is 27

If we look at a number line, it would take 9 to get back to 0 from -9 then 18 more to get to 18

9 + 18 = 27

Hope this helps

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
