5(9-x)/3 +1 less than 11<br>find x

Lunna [17]

Answer:

x > $\frac{1}{5}$

Step-by-step explanation:

$\frac{5(9-x)}{3+1}$

Add 3 and 1 to get 4.

$\frac{5(9-x)}{4}$

Use the distributive property to multiply 5 by 9−x.

$\frac{45-5x}{4}$

Subtract 45/5 from both sides.

$-\frac{5}{4}x$

Since 44/4 and 45/4 have the same denominator, subtract them by subtracting their numerators.

$-\frac{5}{4} x$

Multiply both sides by -4/5, the reciprocal of -5/4. Since -5/4 is negative, the inequality direction is changed.

$x>-\frac{1}{4} (-\frac{4}{5} )$

Multiply -1/4 times -4/5 by multiplying numerator times numerator and denominator times denominator.

$x>\frac{-(-4)}{4 x 5}$

$x>\frac{1}{5}$

F(x)=x^2-1 <br> G(x)=x-1 <br> find (f+g)(10).

WARRIOR [948]

<h2>Adding Functions</h2><h3>Answer:</h3>

$(f +g)(10) = 108$

<h3>Step-by-step explanation:</h3>

Before we can solve for $(f +g)(10)$ , we need to know how $(f +g)(x)$ is defined.

$(f +g)(x) = f(x) +g(x) \\ (f +g)(x) = (x^2 -1) +(x -1) \\ (f +g)(x) = x^2 -1 +x -1 \\ (f +g)(x) = x^2 +x -2$

We can now solve for $(f +g)(10)$ :

$(f +g)(10) = (10)^2 +(10) -2 \\ (f +g)(10) = 100 +10 -2 \\ (f +g)(10) = 108$
