HELP ASAP THANKS - FIRST IS BRAINLIEST
galina1969 [7]

Answer:

C.

Step-by-step explanation:

Even if it is a piecewise function, we don't really need to approach it that way. Since both of the given equations have a slope, our only viable option is C because it is the only graph that shows the 2 slopes. All the other graphs show 1 slope and a 0 slope (horizontal line) so C. is our best choice.

svetoff [14.1K]

Answer:

  • n = 7, x = 9

Step-by-step explanation:

The top and bottom segments have same length.

a)

  • n + n + 19 = 33
  • 2n + 19 = 33
  • 2n = 33 - 19
  • 2n = 14
  • n = 14/2
  • n = 7

b)

  • x + x + x + 3 = 30
  • 3x = 30 - 3
  • 3x = 27
  • x = 27/3
  • x = 9

In the piece-wise function graphed below, which is the correct equation for when − 2 ≤ x ≤ 2
Rama09 [41]

Answer:

y=-\frac{1}{2}x+2

Step-by-step explanation:

Looking at the graph

For x=-2 ---> f(x)=3

For x=2 ---> f(x)=1  

so

we have the points

(-2,3) and (2,1)

Find the slope

m=(1-3)/(2+2)=-\frac{1}{2}

The equation of the line in slope-intercept form is equal to

y=mx+b

we have

m=-\frac{1}{2}

b=2 ---> see the graph

substitute

y=-\frac{1}{2}x+2
