Distribute it out. you should end up with (y^2+7y) + (5y+35) add the 7y and the 5y to get 12y. you will have y^2+12y+35. tbh i have no idea what to do from there. its been so long since i have studied this

Which of the following systems of inequalities has Point C as a solution?

sleet_krkn [62]

Answer:

Option A.

$f(x)\leq 3x+4$

$g(x) \leq-\frac{1}{2}x-5$

Step-by-step explanation:

we know that

If point C is a solution of the system of inequalities, then point C must satisfy both inequalities

Point C is located below the solid line f(x) and below the solid line g(x)

The shaded region of the solution set of the system must be below of the inequality f(x) and must be below of the inequality g(x)

therefore

The system is

$f(x)\leq 3x+4$

$g(x) \leq-\frac{1}{2}x-5$

How fast does a driven gear turn if it has 25 teeth (t) and is driven by a10-tooth driver gear (T) at 250 RPM?

vazorg [7]

Given:

The number of teeth = t = 25

The gear is driven by a 10-tooth driver gear (T) at 250 RPM

Let the speed = s

So, using the ratio and proportion

$\frac{25}{s}=\frac{10}{250}$

Solve for s:

$\begin{gathered} 10s=25\cdot250 \\ \\ s=\frac{25\cdot250}{10}=25\cdot25=625 \end{gathered}$

So, the fear will be driven by 625 RP
