Answer:

(f - g)(x) = -x² + 4x + 4

General Formulas and Concepts:

Pre-Algebra

Properties

Algebra I

Combining like terms
Function notation

Step-by-step explanation:

Step 1: Define

f(x) = 4x - 1

g(x) = x² - 5

(f - g)(x) = f(x) - g(x)

Step 2: Find

Substitute: (f - g)(x) = 4x - 1 - (x² - 5)
Distribute: (f - g)(x) = 4x - 1 - x² + 5
Combine like terms: (f - g)(x) = -x² + 4x + 4

What is the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1)?

Debora [2.8K]

The point-slope form:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (7, 5) and (-4, -1). Substitute:

$m=\dfrac{-1-5}{-4-7}=\dfrac{-6}{-11}=\dfrac{6}{11}$

$y-(-1)=\dfrac{6}{11}(x-(-4))\\\\\boxed{y+1=\dfrac{6}{11}(x+4)}$

The graph for the equation y=-2x+1 is shown below.

Tpy6a [65]

Answer:

Step-by-step explanation:

Given the equation y=-2x+1 and given another equation y=mx+b in order for us to have no solution we must guarantee that both lines do not intersect. Recall that m is the slope of the second equation and b the y-intercept. To guarantee that both lines don't intersect, they must be parallel. To have this result, we must have that they have the same slope but different y intercept. That is take m = -2 and b any value different to +1. For example, the b = 6. So

y = -2x+6 = -2(x-3) is another equation that gives no solution to the system.
