Answer:

D) x<0 or x>3

Step-by-step explanation:

x(x-3)>0

either x>0 and x-3>0      .... positive-positive=positive   so x>3

or x<0 and x-3<0    ..... negative-negative=positive  so x<0

if x=0 then x(x-3)=0

The solution to the inequality is x < 0 or x > 3

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To solve the inequality x(x - 3) > 0, we can use a sign chart.

First, we can find the critical points of the inequality, which are the values of x that make the expression x(x - 3) equal to zero. These values are x = 0 and x = 3.

Then, we can create a sign chart with these critical points and test intervals between them to determine the sign of the expression x(x - 3) in each interval.

Interval Test Value x(x - 3)

x < 0   -1                Positive

0 < x < 3    1                  Negative

x > 3    4                Positive

From the sign chart, we see that x(x - 3) is positive when x < 0 and when x > 3, and negative when 0 < x < 3.

Hence , the solution to the inequality x(x - 3) > 0 is x < 0 or x > 3

Answer:

x = 144

Step-by-step explanation:

[tex] x^\frac{1}{2} - 4 = 8 [/tex]

Add 4 to both sides.

[tex] x^\frac{1}{2} = 12 [/tex]

Square both sides since x^(1/2) is the same as sqrt(x).

[tex] (x^\frac{1}{2})^2 = (12)^2 [/tex]

[tex] x^{\frac{1}{2} \times 2} = 144 [/tex]

[tex] x^1 = 144 [/tex]

Answer:

11 / 9

Step-by-step explanation:

Let number = x

(x * 9) + 4 = 15

9x + 4 = 15

9x = 15 - 4

9x = 11

x = 11 / 9

Hence, the number is 11 /9

x^2 + 8x +7

Step-by-step explanation:

x times x = x^2, with 7 times x = 7x and x times 1 = 1x. Add those two common terms together to get 8x. Then lastly 7 times 1 =7 so add that.

Simplify form of (x + 1)(x + 7) is equals to x² +8x +7.

"Simplification in mathematics means to write the given expression in such a way that it is easy to understand."

According to the question,

Simplify the given equation by opening the brackets we get,

  (x + 1)(x + 7)

=  x² + 1x +7x +7

= x² + 8x + 7

Hence, simplify form of (x + 1)(x + 7) is equals to x² +8x +7.

Answer:

The equation of the function is;

y = |x-3| -3

Step-by-step explanation:

Here, we want to give the absolute-value function

For the minimum value to be -3, it means that k is negative

since the domain is the set of all real numbers, then we do not have any undefined value for the range y

So, the equation is ;

y = |x-3| - 3

Answer:

50%

Step-by-step explanation:

Given that :

Let Probability of rain today = P(rain today) = 50% = 0.5

The complement of an event A denoted as A' means the opposite of event A is obtained by subtracting event a from 1.

P(rain today) = 0.5

The complement of P(rain today) ; means the probability that it will NOT rain today;

Hence, P(raintoday') = 1 - 0.5 = 0.5 = 50%
