What is the value of x ?

Mathematics
1 answer:
valina [46]3 years ago
4 0

Answer:

The value of x = 9

Step-by-step explanation:

∵ The figure has right angle and a line ⊥ from the right angle to the hypotenuse

∴ There is a relation between the ⊥ line and the two parts of the hypotenuse

∴ (⊥)² = multiplication of the two parts of the hypotenuse

∴ (6)²= 4 × x

∴ 36 = 4 × x

∴ x = 36/4 = 9

Given that a function, g, has a domain of -1 ≤ x ≤ 4 and a range of 0 ≤ g(x) ≤ 18 and that g(-1) = 2 and g(2) = 8, select the st
Juli2301 [7.4K]

Answer:

Option 4 is correct.

Step-by-step explanation:

Consider a function g, it has a domain of -1 ≤ x ≤ 4 and a range of 0 ≤ g(x) ≤ 18. It is given that g(-1) = 2 and g(2) = 8.

The statement g(5) = 12 is not true because the value of x is 5 which is not in its domain.

The statement g(1) = -2 is not true because the value of function g(x) is -2 which is not in its range.

The statement g(2) = 4 is not true because g is a function and each function has unique output for each input value.

If g(2)=8 and g(2)=4, then the value of g(x) is 8 and 4 at x=2. It means g(x) is not a function, which is contradiction of given statement.

The statement g(3) = 18 is true because the value of x is 3 which is in the domain and the value of function g(x) is 18 which is in its range.

Therefore, the correct option is 4.

Between the square roots of 7 and 8, because e^2 is equal to around 7.4, which is between 7 & 8. I hope this helps!

Evaluate g(n-7) if g(x) =x^2-5 / 3x
aleksandrvk [35]

Answer:

g(n-7)=\frac{n^2-14n+44}{3n-21}

Step-by-step explanation:

The given function is

g(x)=\frac{x^2-5}{3x}

To find g(n-7), we substitute x=n-7 to obtain;

g(n-7)=\frac{(n-7)^2-5}{3(n-7)}

Expand the parenthesis to obtain;

g(n-7)=\frac{n^2-14n+49-5}{3n-21}

Simplify:

g(n-7)=\frac{n^2-14n+44}{3n-21}

If f ( x ) = 3x² - 5x + 7 , Show that f ( -1 ) = 3 f ( 1 ) .<br><br><br><br><br>Tysm :')​
Lelechka [254]

Solution :

  • 3x² - 5x + 7

put x = -1

  • 3(-1)² - 5(-1) + 7

  • 3(1) + 5 + 7

  • 3 + 12

  • 15

Now, put x = 1

  • 3(1)² - 5(1) + 7

  • 3(1) - 5 + 7

  • 3 + 2

  • 5

here :

  • f(-1) = 15

  • f(-1) = 3(5)

  • f(-1) = 3 f(1)
