Answer: She has to score a minimum of 92 marks to take her average to 80
Step-by-step explanation:
Let the equation be
Three months total = 76 x 3 = 228
(x + 228) / 4 = 80
x + 228 = 80 x 4
x = 320 - 228
x = 92
First one is the answer
x = +- sqrt (10)
B. Sometimes because in learned that it isn't always that way.
- The slope of the graph of the function is equal to 0 for x between x = -3 and x = -2.
- The slope of the graph of the function is equal to 0 for x between x = 3 and x = 4.
- The greatest value of y is y = 4.
- The smallest value of y is y = -3.

By critically observing the graph shown in the image attached below, we can logically deduce that the slope of the graph of this function is equal to 0 for x, between x = -3 and x = -2.
Similarly, the slope of the graph of this function is also equal to 0 for x, between x = 3 and x = 4.
Based on the graph (see attachment), the greatest value of y is 4 while the smallest value of y is -3.
