Answer:
No 2 bleachers would be correct answer
Answer:
10
Step-by-step explanation:
Find the mean
9+12+10+15+15+15+10+x/8=12
divide 86+x/8=12
multiply both sides by 8
86+x=96
sub 86 from both sides
x=10
hope this helps
Answer:
3x+11 = 65, so x will equal 18
Vertex<em> </em>is at ![\left(-3,-6\right)](https://tex.z-dn.net/?f=%5Cleft%28-3%2C-6%5Cright%29)
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
Step-by-step explanation:
The graph of the equation is hereby attached in the answer area.
Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here(
), is shown with the dotted line in the graph attached.
<em>y-intercept </em>is defined as the value of y where the graph crosses the y-axis. In other words, when
. Putting
And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of
in the given equation
. Here, co-efficient of
So, vertex<em> </em>is at ![\left(-3,-6\right)](https://tex.z-dn.net/?f=%5Cleft%28-3%2C-6%5Cright%29)
<em>y-intercept</em> is 3.
The parabola <em>opens up</em>.
