Examine rectangle JKLM, shown below.

Mathematics
1 answer:
IRISSAK [1]3 years ago
5 0

Answer:

NM = 8

Step-by-step explanation:

Given rectangle JKLM

JN = x + 3 and JL = 3x + 1

JN = 1/2JL as diagonals bisect each other and N is the midpoint of JL.

Substitute and solve for x:

x + 3 = 1/2(3x + 1)

2x + 6 = 3x + 1

3x - 2x = 6 - 1

x = 5

Find JN

JN = 5 + 3 = 8

Looking at the options, we see that

NM = JN = 8

Correct option is A

If xy + x = 12 and dx/dt = -3, then what is dy/dt when x = 2 and y = 5?
dlinn [17]
If xy + x = 12, then
\dfrac{d}{dt}(xy+x)=  \dfrac{d}{dt}(12).
Use the chain rule:
y\dfrac{dx}{dt}+x \dfrac{dy}{dt}+ \dfrac{dx}{dt}=0,
Since x=2, y=5, <span>dx/dt = -3, then
</span>
5\cdot (-3)+2\cdot \dfrac{dy}{dt}+(-3)=0, \\ 2\cdot \dfrac{dy}{dt}=18, \\ \dfrac{dy}{dt}=9.
