PLEASE HELP!
____ [38]
<h3>Answer:</h3>
  • A. x = -2
  • B. (-2, -3), (-3, -1)
  • C. x = 0
<h3>Step-by-step explanation:</h3>

Part A. The solution is represented by the point at which the graphs intersect: (-2, -3). The x-value that makes p(x) = f(x) is x = -2.

___

Part B. The point found in Part A is one solution to f(x). The graph shows the line has a slope of -2, so another point will be 1 to the left and 2 up: (-3, -1). So, two solutions are ...

... (-2, -3) and (-3, -1)

___

Part C. The graphs of p(x) and g(x) intersect at the point (0, 2). This means

... p(0) = g(0) = 2

So, x = 0 is the solution to the equation p(x) = g(x).

Change word phrase to expressions or equations<br><br> The sum of p and 45 less than 89
stellarik [79]

Answer:

p + 45 < 89

Step-by-step explanation:

The sum of something is the result of addition so you know that they are adding p and 45 together. They then state that p plus 45 must be less than 89. You can show that by using the less than symbol "<"

If you want to find all of the different values that P could equal then all you have to do is subtract 45 from both sides so the equation would be

p < 44

this means that p can equal anything less than 44 for this statement to be valid. Hope this helped!
