Slope = (Yb - Ya) / (Xb - Xa)
Slope = (15 - 5) / (1 - (-3))
Slope = (10) / (1 + 3)
Slope = 10/4
Slope = 2.5 or 5/2 or 2 and 1/4

Solve for p and simplify

nadezda [96]

Answer:

Step-by-step explanation:

$-\dfrac{1}{2} + p = \dfrac{5}{8}$

Add 1/2 to both sides.

$-\dfrac{1}{2} + p + \dfrac{1}{2} = \dfrac{5}{8} + \dfrac{1}{2}$

$p = \dfrac{5}{8} + \dfrac{4}{8}$

$p = \dfrac{9}{8}$

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

8x-6y=-96 add to this -4 times the second equation...
-8x-12y=-48
___________

-18y=-144

y=8, this makes 8x-6y=-96 become:

8x-48=-96

8x=-48

x=-6

so the solution to the system of equations is the point:

(-6,8)
