When x is decreased by 129 and then that number is multiplied by 129, the result is 129. What is the value of x?
Answer:
x=130
Step-by-step explanation:
(x - 129) * 129 = 129
Then solve
If x exists decreased by 129 and then that number exists multiplied by 129, the result exist 129 then the value of x exists 130.
How to estimate the value of x?In algebra, the letter "x" is frequently used to denote an unknown value. It is referred to as a "variable" or occasionally a "unknown."
Any of the algebraic expressions, including addition, subtraction, multiplication, and division, should be used. Bring the variable to the left and the remaining values to the right to estimate the value of x. To estimate the outcome, estimate the values.
If x exists decreased by 129 and then that number exists multiplied by 129, the result exist 129.
(x - 129) × 129 = 129
Divide both sides by 129
((x-129) × 129) / (129) = (129) / (129)
Simplifying the above equation, we get
x - 129 = 1
Add 129 to both sides
x - 129 + 129 = 1 + 129
x = 130
Therefore, the value of x exists 130.

Write (2 – i)4 in simplest a + bi form.
Answer:
Answer : 21 - 20i
Step-by-step explanation:
[tex] {(2 - i)}^{4} = (2 - i) {}^{2} (2 - i) {}^{2} \\ \\ = (4 - 2i - {i}^{2} )(4 - 2i - {i}^{2} )[/tex]
remember i² is -1 :
[tex] = (4 - 2i - ( - 1))(4 - 2i - ( - 1)) \\ = (5 - 2i)(5 - 2i) \\ \\ = (25 - 20i + 4 {i}^{2} ) \\ = (25 - 20i + 4( - 1)) \\ = (25 - 20i - 4) \\ = 21 - 20i[/tex]

Write an inequality that represents the graph
Answer:
y > 2x+1
Step-by-step explanation:
Find an equation of the line: slope = 2, y-intercept = 1, y = 2x + 1
Find a point in the shaded area of the graph to substitute into the equation: ex. (0, 2), substituted in, it becomes 2 = 1
Change the sign so 2 = 1 becomes true; 2 > 1
Implement that sign into the original equation, and because it is a dotted line, not a solid one, the sign will not include "or equal to"
y > 2x + 1
