Step-by-step explanation: All you have to do is combine like terms

First, you combine 3x - 6x which, will give you -3x

Second, you combine 12 - 5 which will give you 7

  3x - 6x = -3x

  12 - 5 = 7

So, combine the answers and you will get -3x + 7

Answer:

x = 6y = 55

Step-by-step explanation:

Angles opposite congruent sides are congruent, so base angles D and F of this isosceles triangle have the same measure:

  y = 55

__

The sum of angles in the triangle is 180°, so ...

  55° +(11x +4)° +55° = 180°

  11x = 66 . . . . . . . . divide by °, subtract 114

  x = 6 . . . . . . . . . . .divide by 11

The values of x and y are 6 and 55, respectively.

Answers

Answer:

C

Step-by-step explanation:

the range is all the possible numbers on the Y axis. We can see that the graphs peaks at 3 and then goes down both ways. This means that eventually the y axis will be equal to all real numbers less than 3

The range of the function looks to be all real numbers less than or equal to -1, according to the provided graph. The best choice is B.

What is a range of a function?

This is due to the fact that the graph's horizontal line at y=-1, which shows that the function accepts all values less than or equal to -1, stretches eternally in both directions.

The collection of all potential output values that a function can take on is generally referred to as the function's range. You can look at the vertical spread of the graph to see what values the function can take on in order to determine the range of a function from its graph.

Observe that the accompanying graph features a horizontal line at y=-1 that spreads out infinity in both directions. This indicates that for all values of x, the function takes on the value of -1.

The graph also features a vertical line at x=2 that goes on forever in both directions, as can be seen. This shows that the function can accept any value of y for x=2.

Combining these findings, we can determine that the function has a range of all real numbers less than or equal to -1 since it takes on the value of -1 for all x and the range of potential values of y is unrestricted.
