Answer:

x<12

Step-by-step explanation:

Let's solve your inequality step-by-step.

−3< x/ −4

Step 1: Simplify both sides of the inequality.

−3< −1/ 4 x

Step 2: Flip the equation.

−1/ 4 x>−3

Step 3: Multiply both sides by 4/(-1).

( 4/ −1 )*( −1/ 4 x)>( 4 /−1 )*(−3)

x<12

Answer:

x<12

Find the second derivative y=1/5x^2+1/11x

Amiraneli [1.4K]

$\frac{dy}{dx}=\frac{1}{5}.x^{2-1}.2 + \frac{1}{11}.x^{1-1}.1$

$\frac{dy}{dx}=\frac{2}{5}.x+\frac{1}{11}$

$\frac{d^2y}{dx^2}=\frac{2}{5}.x^{1-1}.1$

$\frac{d^2y}{dx^2}=\frac{2}{5}$

Solve for ddd. Give an exact answer. 0.5(7d+4)=7-1.5d0.5(7d+4)=7−1.5d0, point, 5, left parenthesis, 7, d, plus, 4, right parenth

MissTica

Answer:

d = 1

Step-by-step explanation:

The equation given is:

0.5(7d + 4) = 7 - 1.5d

Expand the bracket:

3.5d + 2 = 7 - 1.5d

Collect like terms:

3.5d + 1.5d = 7 - 2

5d = 5

d = 5 / 5 = 1

What’s the answer to this question if your right I’ll keep giving you points

$\huge\text{$m\angle O=\boxed{11^{\circ}}$}$

Since we know that all angles in a triangle add up to $180^{\circ}$ , we can solve for $x$ and substitute it back into $(x-5)^{\circ}$ to find $m\angle O$ .

$\begin{aligned}m\angle N+m\angle O+m\angle P&=180\\(5x-8)+(x-5)+(6x+1)&=180\end{aligned}$

Remove the parentheses and combine like terms.

$\begin{aligned}5x-8+x-5+6x+1&=180\\(5x+x+6x)+(-8-5+1)&=180\\12x-12&=180\end{aligned}$

Add $12$ to both sides of the equation.

$\begin{aligned}12x-12&=180\\12x&=192\end{aligned}$

Divide both sides of the equation by $12$ .

$\begin{aligned}x=16\end{aligned}$

Now that we have the value of $x$ , we can substitute it back into $(x-5)^{\circ}$ to find $m\angle O$ .

$\begin{aligned}m\angle O&=(x-5)\\&=16-5\\&=\boxed{11}\end{aligned}$
