Answer: boat
Step-by-step explanation: the farthest it can go is weeks
Y < 13
u will have an open circle on 13 (it will be open because there is no equal sign)....with shading to the left (because less then means shade to the left)

Answer:
Step-by-step explanation:
y = a(x - p)^2 + q....the graph of the parabola represented by this quadratic function has an axis of symmetry represented by the equation x = p.
f(x) = (x + 3)^2 - 4.....the axis of symmetry is in the p position of the formula used above.....so the axis of symmetry is -3, therefore, ur equation is x = -3
but before u do anything, u have to make sure ur quadratic equation is in vertex form...in the form of y = a(x - p)^2 + q
Answer:
(b) Yes, it is divisible by 9
Step-by-step explanation:
Given
Solving (a): Complete the blanks
![6m(3m + 21) = 9 [\ ]](https://tex.z-dn.net/?f=6m%283m%20%2B%2021%29%20%3D%209%20%5B%5C%20%5D)
Expand the bracket
![6m(3[m + 7]) = 9 [\ ]](https://tex.z-dn.net/?f=6m%283%5Bm%20%2B%207%5D%29%20%3D%209%20%5B%5C%20%5D)
![6m*3(m + 7) = 9 [\ ]](https://tex.z-dn.net/?f=6m%2A3%28m%20%2B%207%29%20%3D%209%20%5B%5C%20%5D)
Express 6m as 2m * 3
![2m*3*3(m + 7) = 9 [\ ]](https://tex.z-dn.net/?f=2m%2A3%2A3%28m%20%2B%207%29%20%3D%209%20%5B%5C%20%5D)
![2m*9(m + 7) = 9 [\ ]](https://tex.z-dn.net/?f=2m%2A9%28m%20%2B%207%29%20%3D%209%20%5B%5C%20%5D)
Rewrite as:
![9 * 2m(m + 7) = 9 [\ ]](https://tex.z-dn.net/?f=9%20%2A%202m%28m%20%2B%207%29%20%3D%209%20%5B%5C%20%5D)
Multiply the bracket by 2m
![9 * (2m^2 + 14m) = 9 [\ ]](https://tex.z-dn.net/?f=9%20%2A%20%282m%5E2%20%2B%2014m%29%20%3D%209%20%5B%5C%20%5D)
Divide both sides by 9
![2m^2 + 14m = [\ ]](https://tex.z-dn.net/?f=2m%5E2%20%2B%2014m%20%3D%20%5B%5C%20%5D)
<em>Hence, the bracket will be filled with: </em>
<em></em>
<em>So:</em>
Solving (b): Is divisible by 9?
In (a), we have:
The leading factor "9" implies that the expression is divisible by 9
