The temperature in Minsk was recorded over a period of four hours. The equation
y=-5x + 54
describes the temperature over this time, where y is the temperature in
degrees Fahrenheit (°F) and x is the number of hours since measurements
started. Which of the following statements correctly describes the
temperature?
O A. It was 54°F when the temperature was first measured, and it is
dropping by 5 degrees per hour.
B. It was -5°F when the temperature was first measured, and it is
rising by 54 degrees per hour.
C. It was 54°F after four hours, and it is dropping by 5 degrees per
hour.
D. It was -5°F after four hours, and it is rising by 54 degrees per hour.

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

answer: 298143

step-by-step explanation:

heyyy

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
