The equation would be ... Y = 2x + (-5)
A quadratic equation always has exactly two solutions. If the quadratic
expression is a perfect square, then they're both the same solution.

Answer:
Part A)
Part B)
Part C) The graph in the attached figure
Step-by-step explanation:
Part A) Model with an inequality.
Let
w -----> the limit of weight in an elevator
we know that
The inequality that represent this situation is
Part B)
Solve the inequality
solve for w
Subtract 35 sides
All real numbers greater than 1,015 pounds
Part C) Where would the solution for the inequality be graphed on the number line?
The solution is the interval -------> (1,015,∞)
In a number line is the shaded area at right of the number x=1.015 (open circle)
see the attached figure
Answer:So you need to calculate a weighted average, where the average of 70 has twice the weight of the average of 85 (20 students vs 10). The easiest way to think about it is to split the 20 into two groups of 10 so that you have three groups of 10 students, that way you can just average the scores as normal.
So, you have three averages of 85, 75 and 75.
Total average = (85+75+75)/3 = 78.33... hopes this helps
