Answer:
The mean is 7
Step-by-step explanation:
5,5,7,7,9,13
9-7 is going to get 7
The correct answer is C, x is greater than -5. In order to solve this, you have to solve for x by simplifying both sides of the equation. Then you have to isolate the variable. Hope this helped!
The x coordinate of the vertex will be the average of the two zeros, here -3 and 5, so x=(-3+5)/2 = 1, f(1)=(1+3)(1-5) = -16.
Answer: (1, -16)
Let's do it some other ways. How about completing the square to turn f in to vertex form?
f(x) = (x+3)(x-5) = x² - 2x - 15 = (x² - 2x + 1) - 1 - 15 = (x-1)² - 16
and now we can read off (1, -16) as the vertex.
The other method is the vertex is x= - b/2a = - (-2)/2(1) = 1.
Three methods, same answer. Good.
Answer:
∠ FGH = 125°
Step-by-step explanation:
The consecutive angles in a parallelogram are supplementary, then
∠ FGH + ∠ GHJ = 180° , that is
∠ FGH + 55° = 180° ( subtract 55° from both sides )
∠ FGH = 125°
Answer:
Step-by-step explanation:
<em>Time</em><em> </em>is the dependent variable, so you set your function equal to <em>s</em>. Then, the correlation of the graph has a 
<em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] from the y-intercept of ![\displaystyle [0, 20],](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B0%2C%2020%5D%2C)
so we choose this answer choice.
I am joyous to assist you anytime.
