Hi there! :)

According to the exterior angle theorem, the angle ∠ADC is equal to the sum of ∠C and ∠B. Therefore:

120 = (15 + 5) + (22x + 4)

Combine like terms:

120 = 37x + 9

Subtract 9 from both sides:

111 = 37x

Divide both sides by 37:

x = 3.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
