A rhinoceros weight when rounded to the nearest thousand was 4,000 pounds. Which of these is the least the rhinoceros could have

Rudik [331]

Answer:

B- 3,500.

Step-by-step explanation:

This is because 3,500 is the lowest number that can be rounded to 4,000.

3,999 and 4,001 can also be rounded but.. (let me show you an image to help).

3,500 < 3,999 < 4,001.

That goes from smallest to largest numbers that round to 4,000.

Hope that helps. x

If 3x-y=123x−y=123, x, minus, y, equals, 12, what is the value of \dfrac{8^x}{2^y} 2 y 8 x start fraction, 8, start superscrip

julia-pushkina [17]

Answer:

$2^{12}=4,096$

Step-by-step explanation:

You know that $3x-y=12$ and have to find

$\dfrac{8^x}{2^y}$

Use the main properties of exponents:

1. $(a^m)^n=a^{m\cdot n}$

2. $\dfrac{a^m}{a^n}=a^{m-n}$

Note that

$8=2^3,$

then

$7^x=(2^3)^x=2^{3\cdot x}=2^{3x}$

Now

$\dfrac{8^x}{2^y}=\dfrac{2^{3x}}{2^y}=2^{3x-y}$

Since $3x-y=12,$ then $2^{3x-y}=2^{12}=4,096$

What is the value of f(-2) if f(x) = - 3x2 + 4x - 1

pashok25 [27]

Given the function below:

$\large{f(x) = - 3 {x}^{2} + 4x - 1}$

To find f(-2), we substitute x = -2 in the equation. Since f(-2) means the value of f(x) at x = -2.

$\large{f( - 2) = - 3 {( - 2)}^{2} + 4( - 2) - 1}$

Replace x-term to -2 and evaluate.

$\large{f( - 2) = - 3(4) - 8 - 1} \\ \large{f( - 2) = - 12 - 8 - 1 \longrightarrow f( - 2) = - 21}$

Answer

f(-2) = -21

Someone please help me. ASAP

marishachu [46]

Answer:

x=1

Step-by-step explanation:

7/3 x + 1/3x = 1 + 5/3 x

Combine like terms

8/3 x = 1 +5/3 x

Subtract 5/3 x from each side

8/3x -5/3x = 1 + 5/3x -5/3x

3/3x = 1

x =1
