Answer:
(b) {-8, 2}
Step-by-step explanation:
The given equation
x³ +6x -16 = 0
cannot be factored in integers. It has one irrational real root near x=1.759, and two complex roots.
__
Perhaps you want to factor ...
x² +6x -16 = 0
(x +8)(x -2) = 0
This has solutions x = -8 and x = 2 that make the factors be zero.

"Cubed" refers to an exponent of 3.
Answer:
Length of beads altogether in the necklace = 3.75 cm
Step-by-step explanation:
Length of the beads used in a necklace = cm
Number of beads used in the necklace = 3
Therefore, length of beads in the necklace = Length of each bead × Number of beads used
=
=
= 3.75 cm
Length of the beads altogether in the necklace = 3.75 cm
Answer:
B
Step-by-step explanation:
To find the constant of proportionality between y and x, divide for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
Using the method above, you should get:
Chart A = 2/5
Chart B = 1/5 (Correct Answer!)
Chart C = N/A
Hope this helps!
