The temperature rises 15 degrees fahrenheit (ﾟf) and then drops by 8ﾟf. if the temperature started at -11ﾟf, what temperature change would be required to bring the temperature to 0ﾟf?

a) an incase of 4ﾟf
b) a decreased of 4ﾟf
c) a decreased of 19ﾟf
d) an increase of 19ﾟf

the answer is A)

Step-by-step explanation:

-11 + 15 = 4

4 - 8 = -4

-4 + 4 = 0

Hello

The temperature rises 15 degrees Fahrenheit (ﾟF) and then drops by 8ﾟF. If the temperature started at -11ﾟF, what temperature change would be required to bring the temperature to 0ﾟF?

A) an Incase of 4ﾟF

B) a decreased of 4ﾟF

C) a decreased of 19ﾟF

D) an increase of 19ﾟF

-11 + 15 - 8 = -19 + 15 = -4° F

A) An increase of 4° F

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
