the answer is x is greater then -7

to find this add 4 to each side

then divide by -2.

since you divided both sides by a negative the symbol flips and you get x is greater then -7

Answer:

x > - 7

Step-by-step explanation:

given

- 2x - 4 < 10 ( add 4 to both sides )

- 2x < 14 ( divide both sides by - 2 )

Remembering to reverse the inequality symbol when dividing/multiplying by a negative quantity.

x > - 7 ← reverse the symbol

For nitrogen to be a liquid, its temperature must be within 12.78 °F of –333.22 °F. Which equation can be used to find the maxim

ziro4ka [17]

To determine the maximum and minimum temperatures at which nitrogen remains a liquid, use the equation |x - (-333.32)| = 12.78, where x is equal to the maximum and minimum temperatures. Using this equation, the maximum temperature is -320.54 degrees Fahrenheit while the minimum is -346.10 degrees Fahrenheit.

Are the triangles shown below similar? Explain. If the triangles are similar, write the similarity statement.

Anton [14]

Answer:

Two triangles are similar if they have: all their angles equal; corresponding sides are in the same ratio; But we don't need to know all three sides and all three angles ...two or three out of the six is usually enough. There are three ways to find if two triangles are similar: AA, SAS and SSS: AA
