Approximately how many pages would ms jackson need to translate to earn 750
1 answer:
Supposing a linear model, it is found that Jackson would need to translate 2500 pages to earn $750.
<h3>What is a linear function?</h3>A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem, we suppose that:
- He earns a salary of $500, hence b = 500.
- He earns $0.1 per page translated, hence m = 0.1.
Thus, his salary as a function of the number of pages translated x is given by:
When he earns $750, y = 750, hence:
Jackson would need to translate 2500 pages to earn $750.

The true statement about the function f(x) = -x² - 4x + 5 is that:
- The range of the function is all real numbers less than or equal to 9.
The domain of a function is the set of given values of input for which the function is valid and true.
The range is the dependent variable of a given set of values for which the function is defined.
- The domain of the function: f(x) = -x² - 4x + 5 are all real number from -∞ to +∞
For a parabola ax² + bx + c with the vertex
- If a < 0, then the range is f(x) ≤
- If a > 0, then the range f(x) ≥
- Here; a = -1,
The vertex for an up-down facing parabola for a function y = ax² + bx + c is:
Thus,
- vertex
= (-2, 9)
Range: f(x) ≤ 9
Therefore, we can conclude that the range of the function is all real numbers less than or equal to 9.
