The predicted temperature to the nearest degree fahrenheit, at 9 p.m. is 75  degree fahrenheit.

<h3>Functions and values</h3>

Given the equation that expresses the temperature, in degrees fahrenheit, in London during a day in august as;

t(x) = 9sin(0.4x - 4) + 74,

where;

x is the number of hours after midnight.

If the time is 9pm after midnight, the total number of hours will be 21 hours

Substitute x = 21 into the function to have;

t(21) = 9sin(0.4(21) - 4) + 74

t(21) = 9sin(4.4) +74
t(21) = 9(0.0767)+74

t(21) = 74.69 degree fahrenheit,

Hence  the predicted temperature to the nearest degree fahrenheit, at 9 p.m. is 75  degree fahrenheit.

The predicted temperature is 75° Fahrenheit

<h3>What is trigonometric functions?</h3>

Trigonometric functions show the relationship between the sides and angles of a triangle.

Analysis:

t(x) = 9sin(0.4x - 4) + 74

since it is 9pm, which is 21 hours from 12 midnight, x = 21

t(21) = 9 sin( 0.4 x 21 - 4) + 74 = 75° Fahrenheit

In conclusion, the predicted temperature at 9pm is 75° Fahrenheit

I need help with number 8,please.

Let x be equal to the number of drinks Yasmine consumed. 
Jose had 2 times that drink so his number of consumed drink would be represented by 2x.  
Sally had 3 fewer drink than Jose so her number of consumed drinks would be represented by 2x-3.
Altogether, the three of them consumed 72 drinks so your equation would be:
x+2x+(2x-3)=72
add like terms together:
5x-3=72
have the term with x be alone on one side of the equation, in this case by adding three to both sides:
5x=75
now divide both sides by five for the value of x and your answer is.....
x=15
