B
The value of x does not change in reflection across the x axis while the sign of the value of y is reversed because it travels a distance equal to its distance from the x-axis in the negative y-axis.

How does the graph of the function h(x)=3x^2 different from the graph of the function f(x)=x?
Tasya [4]
The graph of h(x) = 3x^2 is a curved "bowl" like shape that opens upward. The curve is called a parabola. The two ends go on forever upward. It has symmetry along the y axis. 

In contrast, the graph f(x) = x is a straight line that goes through (0,0) and (1,1). This is known as a linear equation.

Answer:

2. 9x+4y=16

    -9x        -9x

4y=-9x+16

----  ----  ----

4      4      4

y= -9x

     --- +4

      4

4. 4x+3y=-9

  -4x         =4x

     3y=-4x-9

     ---    --- ---

     3       3  3

y= -4x

    ---- - 3

      3

6. 7x-3y=6

  -7x      -7x

       -3y=-7x+6

        ---  ----   ---

Ket [755]

Answer:

8

Step-by-step explanation:

Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as

1070=180(n-2) where n is the number of sides required here.

Making n the subject of the formula then following step by step

n-2=\frac {1070}{180}

n=\frac {1070}{180}+2\\n=7.9444444444444\approx 8

Therefore, the shape is octagon and it has 8 sides.
