Standard form of (2,-4) slope : -1

gladu [14]

Y = mx + b
slope(m) = -1
(2,-4)...x = 2 and y = -4
now we sub and find b, the y int
-4 = -1(2) + b
-4 = -2 + b
-4 + 2 = b
-2 = b

y = -x - 2
x + y = -2 <== standard form

The midpoint of segment XY is (6, -3). The coordinates of one endpoint are X(-1, 8). Find the coordinates of endpoint Y.

Snezhnost [94]

Answer:

The answer to your question is: Y = (13, -14)

Step-by-step explanation:

Data

midpoint = mp = (6, -3)

one endpoint = X = (-1, 8)

second endpoint = Y = (x, y)

Formula

Xmp = (x1 + x2) / 2

Ymp = (y1 + y2) / 2

Process

x2 = 2xmp - x1

y2 = 2ymp - y1

x2 = 2(6) - (-1) y2 = 2(-3) - 8

x2 = 12 + 1 y2 = -6 - 8

x2 = 13 y2 = - 14

Y = (13, -14)

Let xy=1<br><br> and let dy/dt=5<br><br> Find dx/dt when x=5

madreJ [45]

<span>So the first step is to take the derivative of xy=1. Don't forget the product chain rule!

</span> $xy=1
\\x=5
\\y= \frac{1}{x}=\frac{1}{5}
\\ 
\\\frac{dy}{dt}=5
\\
\\x\frac{dy}{dt}+y\frac{dx}{dt}=0
\\
\\5\times5+ \frac{1}{5} \frac{dx}{dt}=0
\\
\\\frac{1}{5} \frac{dx}{dt}=-25
\\
\\ \frac{dx}{dt}=-125

How to find word problems related to Zaynnah checks her bike every 9 days for repairs and Amna checks her bike every 12 days. If

Umnica [9.8K]

Answer:

36 days

Step-by-step explanation:

Zaynnah checks her bike every 9 days for repairs and Amna checks her bike every 12 days.

Now, multiples of 9 are 9, 18, 27, 36, 45, ......

And the multiples of 12 are 12, 24, 36, 48, 60, ........

So, the smallest multiple which is common for 9 and 12 is 36.

Therefore, after 36 days they both check their bikes for repair.

If they both check their bikes today, then after 36 days they will check their bikes on the same day. (Answer)
