1.6×(3+2)÷10
shusha [124]
1. 6×(3+2)÷10 = 3

Work:
3+2 = 5
6 × 5 = 30
30 ÷ 10 = 3

2. 12-(3×3)+11 = 14

Work:
3 × 3 = 9
12 - 9 = 3
3 + 11 = 14

3. (10×0.4) + (10×0.8) = 12

Work:
10 × .4 = 4
10 × .8 = 8
8 + 4 = 12

4.(8 ÷ 4)×(4-2) = 4

Work:
8 ÷ 4 = 2
4 - 2 = 2
2 × 2 = 4

5.8.5-10÷2 = 3.5

Work:
10 ÷ 2 = 5
8.5 - 5 = 3.5

6.18-(8÷2)+25 = 39

Work:
8 ÷ 2 = 4
18 - 4 = 14
14 + 25 = 39

I need help finding the domain and range!! -Algebra
statuscvo [17]

Answer:

  • The graph is shown below
  • Vertex = (2,1)
  • Axis of symmetry is x = 2
  • Domain = set of all real numbers
  • Range = set of y values such that y \ge 1

=======================================================

Explanation:

Use your favorite graphing tool to graph the equation. If your teacher doesn't allow you to use graphing software, then you'll have to plug in various x values to find the paired y values. This gives the set of (x,y) points needed to be plotted to form the parabola. The more points you plot, the more accurate the curve.

The graph is shown below. I used GeoGebra to make the graph. It's free graphing software. Desmos is another tool that I recommend.

------------

The lowest point on the parabola is the vertex (h,k) = (2,1) which is shown in the graph below.

This is due to the equation being in vertex form y = a(x-h)^2 + k. We see that h = 2 and k = 1.

-------------

The axis of symmetry is the vertical line that passes through the vertex.

As such, the axis of symmetry equation is simply x = h. So that's how we get to x = 2.

In the graph below, the axis of symmetry is the red dashed line.

-------------

There aren't any restrictions on x. We don't have to worry about dividing by zero or applying a square root to a negative number.

Therefore, any x value is allowed and the domain is the set of all real numbers.

-------------

The range however isn't the set of all real numbers. The lowest y can get is y = 1 due to the vertex point. We can have y = 1 or larger

Therefore, y \ge 1 is the range.
