Answer:
0
Step-by-step explanation:
Well average means mean so we have to find the mean of the numbers in the data set. Our numbers are -12,12,-4, and finally 4. When we add all of them up we get 0 and we have to divide 0 by the 4 thermoters and your answer is 0. if this is confusing just leave a comment and ill try to explain better
Answer: I don’t know what options you have but I graphed it in the picture linked below
Answer:
y=25x+40.50 is not the equation of proportional relationship because if you were to graph the equation, the line would not go through the origin of the graph. You can tell beause of the y-intercept that is given in the equation, 40.50.
Step-by-step explanation:
#1. The answer is B, just put the points on the graphic and you will see.
#2. The answer is A, the equation explained everything.
Similarities
Adding or subtracting a number from both sides.
Multiplying or dividing both sides by a positive number.
Applying an increasing function to both sides.
Simplifying one or both sides.
Differences
Multiplying or dividing both sides by a negative number changes the direction of an inequality. So we cannot multiply or divide both sides by a variable unless we know that the variable is either always positive or always negative. This is not a concern when solving equalities.
When applying a decreasing function to both sides of an inequality, the direction of the inequality changes.
Swapping both sides of an inequality also changes the direction of an inequality. Again we don't have to worry about this with equalities.
