Joaquin recorded a temperature of 62°f this morning for science class. the temperature increased 6 1/2°f in the afternoon before decreasing 8.7°f in the evening. what was the evening temperature?

Step-by-step explanation:

Given : Joaquin recorded a temperature of 62°F this morning for science class.

The temperature increased in the afternoon before decreasing 8.7°F in the evening.

We can write as  .

Now According to the question , the temperature at evening will be :-

Hence, the evening temperature was .

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
