How do I find the value of x?

Mathematics
1 answer:
snow_tiger [21]3 years ago
6 0

opposite angle equal each other so:

(12x-10) = (5x+53)

add 10 to both sides

12x = 5x+63

subtract 5x from each side

7x=63

 divide both sides by 7

x = 63/7

x = 9

If f(x) = 3x - 1 and g(x) = x + 2, find (f - g)(x).
Marat540 [252]

Answer:

(f - g)(x) = 2x - 3

Step-by-step explanation:

(f - g)(x) is defined as subtracting the whole g(x) function from the f(x) function.

Hence, we can define it as:

(3x - 1) - (x + 2)

= 3x - x - 1 - 2

= 2x - 3

Therefore, (f - g)(x) = 2x - 3.

Hope this helped!

Answer: <em>(1,5,7,10,11,15)</em>

To get the union of two sets of numbers, all you do is combine the numbers from least to greatest. If a number repeats in the 2 sets, you only put it once.

The height of a triangle is 4 times its base. if he are of a triangle is 200cm, what is the height
uranmaximum [27]
A = (h * b) / 2
A = 200
h = 4b

200 = (b(4b) / 2
200 * 2 = b * 4b
400 = 4b^2
400 / 4 = b^2
100 = b^2
sqrt 100 = b
10 = b ..... base is 10 cm

h = 4b
h = 4(10)
h = 40 <=== height is 40 cm
