Anna007 [38]

$\huge\text{Hey there!}$

$\huge\textbf{Solving for your equation:}$

$\mathbf{|4x^2| - 3x - (9 - |-3x|)}$

$\mathbf{= |(4)(9)|-(2)(-3)-(9-|(-3)(-3)|)}$

$\mathsf{= |36| - (2)(-3)- (9 - |(-3)(-3)|)}$

$\mathbf{=36 - (2)(-3) - (9 - |(-3)(-3)|)}$

$\mathbf{= 36 -(-6) - (9 - |(-3)(-3)|)}$

$\mathbf{= 42 - (9 - |(-3)(-3)|)}$

$\mathbf{= 42 - (9 - |9|)}$

$\mathbf{= 42 - (9 - 9)}$

$\mathbf{= 42 - (0)}$

$\mathbf{= 42 - 0}$

$\mathbf{= 42}$

$\huge\textbf{Notice that your equation kept getting}\\\huge\textbf{getting smaller and smaller?}\\\\\\\huge\textbf{That's because we kept solving as we got}\\\huge\textbf{closer to your result and we got there}\\\huge\textbf{sooner than we thought :)}$

$\huge\textsf{ANYWAY!}$

22 less than 5 times a number f

Rasek [7]

Answer:

22-5f

Step-by-step explanation:

22 less then 5 would be 22-5 and then you have 5 times a number f so that would make it 5f so you would just attach the f to the 5. I hope this is helpful and is what you are looking for.

Answer:

The range is {1,3,4,7}

Step-by-step explanation:

The range is the output

f = {(2,3), (5, 7), (3, 3), (5, 4), (9, 1))

The range is {3,7,3,4,1}

We normally list the numbers in order from smallest to largest and do not list duplicates

The range is {1,3,4,7}

Karen operates a hot dog stand. On Wednesday she used 9 1/3 bags of hot

trapecia [35]

<h2>Explanation:</h2>

We know that Karen operates a hot dog stand. So we have:

On Wednesday:

$\text{She used} \ 9 \frac{1}{3} \ \text{bags of hot dog buns.}$

On Thursday:

$\text{She used} \ \frac{1}{3} \ \text{as many hot dog buns as on Wednesday}$

Therefore, if x is the amount of hot dog buns she used on Thursday, then:

$x=\frac{1}{3}(9\frac{1}{3}) \\ \\ x=\frac{1}{3}\times 9+\frac{1}{3}\times \frac{1}{3} \\ \\ x=\frac{28}{9}$

Therefore, on Thursday she used 28/9 bags of hot dog buns.

A box contains 9 Identical glass spheres that are used to make snow globes. The spheres are tightly packed. They are held in a 1

Contact [7]

Because the balls or spheres are tightly packed in a cube, their radius is approximately equal to 2 ft. The volume of a sphere is calculated through the equation,
V = 4/3πr³
Substituting the known radius,
V = 4/3π(2 ft)³
V = 33.51 ft³
The 9 spheres will have a total volume of 301/59 ft³ which is also equal to 521152.52 in³.
