You just substitute in what x equals. ex. x=16, x-7 : 16-7=9.

x-7

1. x= -8; -8-7= -15
2. x= -11; -11-7= -18
3. x=16; 16-7= 9

Please help me solve this​
MakcuM [25]

Answer:

a) Function? No

b) Domain: -4\le x\le 2

c) Range: -3\le y\le 3

Step-by-step explanation:

a) Function? No

We want to determine whether the graph of the relation is a function or not.

When we draw a straight line at x=-1, it will intersect the graph at several points, therefore the graph fails the vertical line test and hence it is not a function.

b) The domain refers to all x-values for which the function is defined.

From the graph the domain is -4\le x\le 2 because the ends of the graph are closed.

c) The range is the set of all y-values for which the graph is defined.

From the graph the range is -3\le y\le 3

Answer:

<h2>50°, 60°, 70° (the second answer)</h2>

Step-by-step explanation:

The sum of the angles in a triangle = 180°

We can use the equation:

2x + 80 + 25 - 5x + 6x + 90 = 180

Combine like-terms:

2x + 6x - 5x = 3x

80 + 25 + 90 = 195

195 + 3x = 180

Subtract 195 from both sides:

3x = -15

Divide both sides by -3 to isolate x:

x = -5

Now that you've solved for x, you can replace x with -5 in the equation for each angle.

2(-5) + 80 = 70°

6(-5) + 90 = 60°

25 - 5(-5) = 50°
