2x +x = 5 +4
3x = 9
x =3
y = 2x-4
y =2(3) - 4
y = 6-4
y = 2

Answer:
"The decay factor of voters."
Step-by-step explanation:
The compound decay equation is:
Where
y is the final value (after t years)
P is the initial value (here, 5700)
r is the rate of decay
t is the time in years
Looking at the "(0.94)" factor and matching with the equation, we see this part is:
(1-r) = 0.94
Solving for r,
r 0 1 - 0.94 = 0.06
0.06 * 100 = 6%
So, the decay is 6%
And, we can say (0.94) [[which is 1 - 0.06]], is the decay factor for voters.
First answer choice is right.
Answer:
TrinomialA trinomial is a mathematical expression with three terms.
Example: The definition of a trinomial is a math equation that has three terms which are connected by plus or minus notations. An example of trinomial is 6x squared + 3x + 5. Trinomial means the scientific name of a plant. An example of a trinomial is a name which inclues the genus, species and the variety.
Answer:
1570
Step-by-step explanation:
the formula for surface area of a cylinder is:
A= 2πrh + 2πr²
π aka pi = 3.14
r = 10
h = 15
so now plug in the numbers
A = 2(3.14)(10)(15) + 2(3.14)(10²)
A = 942 + 2(3.14)(100)
A = 942 + 628
A = 1570
Answer: Choice B)
We have some value m and we're squaring it to get
To undo this and isolate m, we apply the square root to both sides
There are two solutions here. This is similar to how there are two solutions in something like (those two solutions being x = 5 and x = -5). Squaring any negative number leads to a positive result because
negative times negative = positive.
