Answer:

35 2-point questions, and 15 5-point questions

Assume x 2-points question, so 50-x 5-points question

Total no of points: 2*x+5*(50-x)=145 points

2x+250-5x=145

-3x=-105

x=-105/-3=35 2-points questions

Remaining 50-35=15 5-points questions

ok so i really hope this helped and if it didn't then sorry

The picture is for the problems....
Paul [167]

Step-by-step explanation:

B: The x axis is the horizontal one. If we look at the graph, there are actually two spots where the line crosses the x axis. It looks to be between -2 and -1 as well as 1 and 2

D: For vertical parabolas such as this, the axis of symmetry is the x coordinate of the vertex. The vertex is essentially the middle point, that, for this graph, is at the bottom. The axis of symmetry is x=0 as that is the x coordinate of the vertex.

E: f(x), in 2D graphs, is typically y, as is the case here. As this parabola opens upward, the minimum point is the vertex, which seems to be -3 for this graph. As the graph seems to be x²-3 or something like that, there is nothing limiting x from being infinity, and when x is equal to infinity in this function, y is as well. Thus, the maximum is infinity.

Points A, B, and C are collinear and B lies between A and C. If AC = 48, AB = 2x + 2, and BC = 3x + 6, what is BC?
tresset_1 [31]

Answer:

<h2>BC = 30</h2>

Step-by-step explanation:

Look at the picture.

The equation:

(2x+2)+(3x+6)=48        <em>combine like terms</em>

(2x+3x)+(2+6)=48

5x+8=48         <em>subtract 8 from both sides</em>

5x+8-8=48-8

5x=40           <em>divide both sides by 5</em>

\dfrac{5x}{5}=\dfrac{40}{5}

x=8

BC=3x+6 - put x = 8:

BC=3(8)+6=24+6=30
