One day, the temperature was 63°F. During the night, the temperature was 38°F. If t represents the change in temperature, what is t?

B -25

Step-by-step explanation: The question is asking how the temperature changed from 63 to 38 the temperature is going down so your answer will be negative and when you do the subtraction(63-38) you get 25

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
