Need help with radical expression!!! It’s asking for a set of all x where the expression is defined in interval form!
gayaneshka [121]

Answer:  (0, 25) ∪ (25, ∞)

<u>Step-by-step explanation:</u>

The expression is undefined when the denominator is equal to zero and when the radicand (expression inside the radical) is less than zero.

Let's deal with the denominator first by finding the x-values that would make the denominator equal to zero (these are the values that will NOT be included in the interval notation)

x - 5√x = 0

x = 5√x          <em>added 5√x to both sides</em>

x² = 25x              <em>squared both sides</em>

x² - 25x = 0             <em>subtracted 25x from both sides</em>

x(x - 25) = 0                 <em>factored the quadratic equation</em>

x = 0   and   x - 25 = 0     <em>applied the Zero Product Property</em>

x = 0   and    x = 25              <em>solved for x</em>

<em />

So, x ≠ 0 and x ≠ 25

Next, let's deal with the radicand by setting the expressions inside the radicals to "greater than or equal to zero".

2√x   and   5√x     both have a radicand of x

x ≥ 0

Now, let's put it all together

x ≥ 0  and    x ≠ 0    and    x ≠ 25    

so, x is between 0 and ∞  but not including 0 or 25.

Interval Notation: (0, 25) ∪ (25, ∞)

Reminder that interval notation uses a bracket [ ] when the value is included and a parenthesis ( ) when the value is not included.  Infinity always uses a parenthesis since it is not an actual number.

Evaluate 8a+3b-10+c^28a+3b−10+c ​2 ​​ 8, a, plus, 3, b, minus, 10, plus, c, start superscript, 2, end superscript when a=2a=2a,
ohaa [14]

Answer:

The given expression  8a+3b-10+c^2 at a = 2 , b = 5 and c = 4  is 37.

Step-by-step explanation:

Given : expression 8a+3b-10+c^2

We have to evaluate the given expression  8a+3b-10+c^2 at a = 2 , b = 5 and c = 4

Consider the given expression  8a+3b-10+c^2

Substitute, a = 2 , b= 5 and c = 4

We have,

=8(2)+3(5)-10+(4)^2

Simplify, we have,

=16+13-10+16

We get,

= 37

So,  The given expression  a+3b-10+c^2 at a = 2 , b = 5 and c = 4  is 37.

Find the x intercept and y intercept for 6x-2y=18 . provide an explanation and show steps
allochka39001 [22]

Answer:

The slope intercept form would be y = 3x - 9

Step-by-step explanation:

To find this slone in slope intercept form, all we need to do is solve for y.

6x - 2y = 18 ---> Subtract 6x from both sides

-2y = -6x + 18 ----> Divide both sides by -2

y = 3x - 9
