What is the value of x?​

Mathematics
1 answer:
Gwar [14]2 years ago
3 0

Answer:

Step-by-step explanation:

First count the number of sides. There are 6 sides.

Now use the formula

(n - 2) * 180  To determine the total of all 6 angles.

(6 -2) * 180 =

4 * 180 = 720

Is that a 9 in x + 9 [lower left]? I'll assume so. Edited to show it was a 4.

x + 4 + 120 + x + 50 + 140 + 112 + x = 720     Combine

3x + 4 + 120 + 50 + 140 + 112 = 720

3x + 426 = 720                                                Subtract 431 from both sides

3x = 720 - 426                                                 Combine

3x = 294                                                          Divide by 3

x = 294/3

x = 98

Answer:

1. As definition, in a function, the set of all possible inputs or possible x values is called the domain.

=> Option 2 is correct.

2. As definition, in a function, the set of all possible outputs or possible y values is called the range.

=> Option 3 is correct.

3. You pay a fixed amount of 70$ and 3$ for each movie.

=> A function that models the total cost: y = 70 + 3x

=> Option 1 is correct

4. Similar to the 3rd, you pay a fixed amount of 5$ to enter and 2$ for each ride.

=> A function that models the total cost: y = 5 + 2x

=> Option 3 is correct.

5.  The average rate of change (R) of f(x) = x2 + 1 from x = 0 to x = 3 is actually the rate of change of line passes (0, 1) and (3, 10) as shown in picture.

=> R = (10 - 1)/(3 - 0) = 9/3 = 3

=> Option 1 is correct.

6. As property of vertical line:  75 = x - 10 + 20

=> x = 75 + 10 - 20 = 65 deg

As property of complement angles: 75 + y = 180

=> y = 180 - 75 = 105 deg

=> Option 2 is correct.

7. Yes, the two triangles are congruent (Side-Angle-Side case) with two sides are equal and the pair of angles created by those pair of 2 sides are also equal.

Hope this helps!
