I wanna know an answer to this math problem I need help with9(p-4)=18 answer
2 answers:
Answer: p = 6
Step-by-step explanation: To solve this equation, we start by distributing the 9 through the parentheses on the left side.
So we have 9 times p which is 9p - 9 times -4 which is -36. So our equation now reads 9p - 36 = 18. Solving from here, we want to add 36 to both sides of the equation to get 9p = 54. Then divide both sides by 9 to get p = 6.
To check our answer, we can substitute a 6 back in for <em>p</em> in the original equation which gives us 9 (6 - 4) = 18 or 9 (2) = 18 or 18 = 18 which is a true statement so we know our answer is correct.

Answer:
Step-by-step explanation:
Range goes from the lowest point on a graph to the highest point, not including anything in between those 2 extremes. We will evaluate the quadratic for the values given. First f(2):
so
f(2) = -1
Now, f(4):
so
f(4) = 11
Now, f(7):
so
f(7) = 44
The lowest y value is -1 and the highest is 44, so the range is from -1 to 44 (I can't tell which of your choices reflects that because it's too small!)
