- 3 is a solution that satisfies both inequalities.So, the correct answer is True.The compound inequality consists of two separate inequalities connected by "and."
1.b ≤ 4:This means that "b" is less than or equal to 4.
2.b > −1:This means that "b" is greater than -1.
If we consider a number line, the values that satisfy both conditions are those that are greater than -1 but also less than or equal to 4. The value -3 falls within this range. It is greater than -1 and also less than 4.
Therefore, -3 is a solution that satisfies both inequalities, making the statement true.

Answer:
Zeros: -3 odd mult.; 0 odd mult.; 2 odd mult.
Positive leading coefficient
Odd degree likely 3
Step-by-step explanation:
A polynomial graph has several features we look for to determine the equations.
Let the number = x
12 + x = 3x - 32
x = 3x - 44 Subtract 12 from both sides
-2x = -44 Subtract 3x from both sides
x = 22 Divide by -2
Answer: Jane started growing Sphere 3 hours ago
Step-by-step explanation:
Farm Rod starting population (Rsp) = 2
Farm Sphere starting population (Ssp) = 8
Let´s name "Rh" the quantity of hours since Rod started growing, and
"Sh" the quantity of hours since Sphere started growing.
And, let´s name "R" the population of farm Rod at 8 p.m. and "S" the population of farm Sphere at 8 p.m.
Population of Rod doubles every hour, therefore:
R =
R =
Population of Sphere is quadrupled every hour, therefore:
S =
S =
At 8 p.m. Jane found that R = S
Therefore, at 8 p.m:
=
dividing both sides by 2
adding exponents
the bases are the same; exponents must be the same
Rh = 2Sh + 2 (equation 1)
And we also know that Jane started growing Rod five hours before Sphere:
Rh = Sh + 5 (equation 2)
Replacing equation 2 into equation 1:
(Sh + 5) = 2Sh + 2
5 - 2 = 2Sh - Sh
3 = Sh, or
Sh = 3
