disa [49]

Answer:

The correct option is (d).

Step-by-step explanation:

Given that,

Jeff earns $14.00 per hour.

Tom earns half as much as Jeff.

Tom's amount = Jeff's amount/2

So,

T=\dfrac{14}{2}\\\\T=\$7

So, Tom earn $7 per hour. Hence, division operation is used. Jeff's amount is divided by 2.

 If length AM = AK then it is isosceles.

M(-1,-6), A(-4,5)

AM=((5-(-6))²+(-4-(-1)))^(1/2)=11.401

A(-4,5) and K(5,-2)

AK=((-2-5)²+(5+4)²)^(1/2)=11.401

so the triangle is isosceles.
