-8m - 12 > -5(m - 8) – 3(m - 7) Write the solution to the inequality

horrorfan [7]

Answer:

No answer.

Step-by-step explanation:

- 8m - 12 > -5m + 40 - 3m + 21

combine terms

-8m - 12 > -8m +61

add 8m to both sides

-12 > 61

negative 12 is not greater than 61

Mrs. Rockwell lost money on an investment at a rate of $4 per day. What integer represents the change in her investment, due to

Lilit [14]

Answer: -112

Step-by-step explanation:

Given: Rate of lost money on an investment = $4 per day.

Since 1 week = 7 days

So, Amount of money she lost in 1 weeks = $ 4 x 7 = $28

⇒ Amount of money she lost in 4 weeks = $ 28 x 4 = $112

Since in integers, a loss is represented by negative integer.

So, Mrs. Rockwell lost $112 after 4 weeks which is represented by "-112" integers.

The coordinates of the vertices of A DEF are D(-4,1), E(3. – 1), and F(-1, – 4)

liq [111]

Answer:

ΔDEF is not a right triangle because no two sides are perpendicular.

Step-by-step explanation:

The coordinates of the vertices of ΔDEF are given to be D(-4,1), E(3,-1) and F(-1,-4).

Now length of DE is given by $\sqrt{(-4-3)^{2}+(1-(-1))^{2} } =\sqrt{53}$ units

length of EF is given by $\sqrt{(3-(-1))^{2}+(-1-(-4))^{2} }=\sqrt{25}$ units

and length of FD is given by $\sqrt{(-4-(-1))^{2}+(1-(-4))^{2} } =\sqrt{34}$ units.

Therefore, 53 ≠ 25+34

Hence, the length of the sides does not support the Pythagoras theorem.

So, ΔDEF is not a right triangle because no two sides are perpendicular. (Answer)
