Answer:

No.

Step-by-step explanation:

$b + 4 < 6 \\ b < 6 - 4 \\ b < 2$

Or we can substitute b = 3 in the Inequality.

$3 + 4 < 6 \\ 7 < 6$

From solving the Inequality, 3 is greater than 2. Therefore, 3 is not the solution.

From substitution, 7 < 6 is false. Therefore, 3 is not the solution.

Given that f(x) = x2 – 3x - 10 and g(x) = x – 5, find (f - g)(x) and express

Roman55 [17]

Answer:

$(f-g)(x)= x^2-4x-5$

Step-by-step explanation:

We have the two functions:

$f(x)=x^2-3x-10\text{ and } g(x)=x-5$

And we want to find (f-g)(x).

(f-g)(x) is equivalent to f(x)-g(x).

Therefore:

$\begin{aligned} (f-g)(x)&=f(x)-g(x)\\ &=(x^2-3x-10)-(x-5)\end{aligned}$

Simplify:

$\begin{aligned} &=x^2-3x-10-x+5 \\ &=(x^2)+(-3x-x)+(-10+5) \\ &=x^2-4x-5\end{aligned}$

Therefore:

$(f-g)(x)= x^2-4x-5$
