<span>y varies inversely with x </span>
<span>y=k/x , where k is any constant </span>
<span>y=-16 when x=-64 </span>
<span>-16 = k/ (-64) </span>
<span>-16 = k/-64 </span>
<span>k=(-16)(-64) = 1024 </span>
<span>2) </span>
<span>y =k/x , where k is any constant </span>
<span>y=8 when x=3 </span>
<span>8 = k/3 </span>
<span>k=24 </span>
<span>y=24/x </span>
<span>when y=6 </span>
<span>6 = 24/x </span>

Answer:
both each side of each triangle is equal
use alphabets to mark each edge of the triangles and prove congruency
The correct option is MN = M'N' since the first two options can be eliminated through the rules of rigid transformations.
Answer:
17
Step-by-step explanation:
If 3 times the quantity is 57, then the quantity is 57/3 = 19.
If 2 more than the number is 19, then the number is 17.
Answer:
x = 6
Step-by-step explanation:
We know that the angles in a triangle add to 180°, so we can add the angles shown in this triangle together, make them equal to 180° and solve for x.
90° + (4x + 3)° + 63° = 180°
90° + 4x° + 3° + 63° = 180°
4x° + 156° = 180°
4x° = 24°
x = 6
So, x = 6. Hopefully, this helped! If you have any further questions, let me know.
