Given:

x + 3 = 18
x > 10

To determine the value of "x", we can isolate it in the equation (x + 3 = 18). This can be done by subtracting 3 to both sides of the equation.

⇒ x + 3 - 3 = 18 - 3

⇒ x = 15

To verify that the value of "x" is 15, we need to substitute the value of x into the inequality (x > 10).

⇒ x < 10

⇒ 15 < 10 (True)

Therefore, the value of "x" is 15.

Answer:

1.05 × 1.05 × 1.05 × 1.05 × 1.05 = 1.2762815625

Step-by-step explanation:

An exponent indicates how many times the base is a factor in the product. That is, 1.05 to the 5th power means ...

1.05⁵ = 1.05 × 1.05 × 1.05 × 1.05 × 1.05

This multiplication expression is evaluated in the usual way.

= 1.1025 × 1.05 × 1.05 × 1.05

= 1.157625 × 1.05 × 1.05

= 1.21550625 × 1.05

= 1.2762815625

All scientific and graphing calculators have a button for computing the power of a number. On my calculator its label is $\displaystyle \boxed{y^x}$ . The particulars of the function of this button can be found in the manual for your calculator.

For on-line calculators, such as the go.ogle calculator, or the Desmos graphing calculator, the caret (^) is used to signify an exponent. (See the input line in the first attachment for an example.)

Answer:

$(x,y) = (-1,-2.5)$

Step-by-step explanation:

Let be $f(x) = \frac{(x+3)^{2}}{x-2}$ and $g(x) = \left|\frac{x}{2}\right| -3$ , we plot each curve with the help of graphic tool. In this case, we use Desmos and outcome is presented in the image attached below. Mathematically speaking, a solution to the system of equation exists when $f(x) = g(x)$ . Graphically speaking, it means that a solution exists when both curves pass through each other.
