Kitty [74]

Answer:           The answer is all real numbers

Step-by-step explanation:

This is the answer because the line goes on infinitely and will pass through all of the numbers (negative, positive). Its not y \geq \\ 0 because it passes through 0 when the line goes through x (side to side) axis.

Kipish [7]

Answer:

{m}^{3}  +  {27}^{m}  + 4 {m}^{2}

Step-by-step explanation:

{m}^{3}  +  {3}^{m 3}  + 4 {m}^{2}

{m}^{3}  +  {3}^{m \times 3}  + 4 {m}^{2}

{m}^{3}  +  {3}^{3m}  + 4 {m}^{2}

{3}^{3m}  =  ({3}^{3}  {)}^{m}  =  {27}^{m}

➡️ {m}^{3}  +  {27}^{m}  + 4 {m}^{2}

PLEASE HELP PICTURE SHOWN
Rainbow [258]
Your answer is B. 2
This is because to rationalise the denominator, we need to multiply it by (3 - √7), so we get:
(3 + √7)(3 - √7)
3 × 3 = 9
3 × √7 = 3√7
3 × -√7 = -3√7
√7 × -√7 = -7
So all in all you get 9 - 7 which is 2.

I hope this helps!

Write an inequality that represents the fact that while making your product
Helga [31]

Answer:

x \leq 40 / 0.25\\ x \leq 160\\

Step-by-step explanation:

If the spending limit is $ 40 and making each beads costs $ 0.25, then the amount of accounts you must do  multiplied by the manufacturing cost should not exceed $ 40.

Then the inequation that this restriction would represent is:

0.25x\leq 40\\

Where x is the number of beads made.

This could also be written more specifically:

x \leq 40 / 0.25\\ x \leq 160\\

Therefore the number of beads must be less than or equal to 160
