Answer:

x = 6

Step-by-step explanation:

According to Exterior Angle Property of a triangle , measure of an exterior angle is the sum of its opposite interior angles.

Using the exterior angle property ,

$17x - 23 = 3x + 17 + 8x - 4$

$= > 17x - 23 = 11x + 13$

$= > 17x - 13x = 23 + 13$

$= > 6x = 36$

$= > x = \frac{36}{6} = 6$

Consider the equations 4(x-3)=16 and 4x-3=16 do they have the same solution? Why or why not ?

Sladkaya [172]

Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation 4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16 there is no variable to multiply with the LHS equation

Solution:

4 (x-3)=16

4x - 12 = 16

4x = 16 + 12

4x = 28

x = 7

4x - 3 = 16

4x = 16 + 3

4x = 19

x = 19/4

x = 4.75

If f (x) = startroot one-half x minus 10 endroot 3, which inequality can be used to find the domain of f(x)? startroot one-half

tankabanditka [31]

A function assigns values. The inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The domain of a function is a set of values for which the equation is satisfied. Since the function has under root values, the value which is under the root should be non-negative so that it does not give a complex number, therefore,

The inequality $\sqrt{\dfrac12x^2-10}\geq 0$ satisfied to find the domain of the function f(x).
