May 4, 2020 · To solve the equation 5x = 7 for x using logarithms, you can use the common logarithm (log) or the natural logarithm (ln). For the exact solution in the form of a logarithm, you take the natural logarithm of both sides, which leads to: ln(5x) = ln(7) x * ln(5) = ln(7) x = ln(7) / ln(5) This is the exact solution represented as a logarithm.

Nov 12, 2023 · In order to solve the equation 13 = 5x - 7, we need to isolate the variable, x. We start by adding 7 to both sides of the equation to get rid of the -7 on the right side: 13 + 7 = 5x - 7 + 7. Simplifying this equation gives us: 20 = 5x. Next, we divide both sides by 5 to solve for x: 20/5 = (5x)/5. This simplifies to: 4 = x.

Oct 31, 2016 · To translate the expression 5 x − 7, we read it as follows: Identify the components of the expression: 5 x: This means 'five times x'. The 'x' is a variable, which can represent a number. − 7: This indicates that seven is subtracted from 5 x. Describe the expression: The expression can be stated as: 'Five times x minus seven.'

Sep 26, 2024 · Sure, let's evaluate (3 x + 2) (5 x − 7) step-by-step: Distribute each term in the first binomial by each term in the second binomial. This involves using the distributive property (also known as the FOIL method, which stands for First, Outer, Inner, Last).

Jun 19, 2018 · In the **expression **f(x) = 5x - 7, the **domain **is all real numbers. The **graph **of the function will be a straight line without discontinuities. Hence, The domain of f(x) = 5x - 7 is {x | x is a real number} and this can be denoted as ( - ∞, ∞) for all x ∈ R. To know more about the Domain click the link given below.

Apr 14, 2021 · The function you've written here y = x2 + 5x - 7 is a quadratic function, which has a characteristic parabola shape. The vertex of this parabola is given by the formula (-b/2a , f(-b/2a)) where a, b and c are the coefficients of the quadratic, …

The equivalent form of the compound inequality −22 > −5x − 7 ≥ −33 is option D. −5x − 7 < −22 and −5x − 7 ≤ −33. In this form, both inequalities are true: -5x - 7 is less than -22 and -5x - 7 is less than or equal to -33. This satisfies the condition in the original compound inequality.

Sep 9, 2020 · An **equivalent **expression with **fewer **terms than 3x - 4 - (5x + 7) is - 2x - 11. What is an expression? An expression is a number, or a variable, or a combination of numbers and variables and operation symbols. Now the **given **expression is, 3x - 4 - (5x + 7) Expanding the brackets we get, 3x - 4 - (5x + 7) = 3x - 4 - 5x - 7
