What is the solution to the compound inequality 3x-8 less than or equal to -5 or 2x - 7 > 5

Mathematics
1 answer:
Svetllana [295]2 years ago
7 0

Answer:

The solution for the compound inequality = ∅

Step-by-step explanation:

The given inequality:

3x - 8 ≤ -5  &  2x - 7 > 5

<u>For the inequality 3x - 8 ≤ -5</u>

3x - 8 ≤ -5    add 8 to both sides

3x  ≤ 3          divide both side by 3

x  ≤ 1

So, the solution of the inequality 3x - 8 ≤ -5 ⇒ x ∈ (-∞ , 1]

<u>For the inequality 2x - 7 > 5</u>

2x - 7 > 5      add 7 to both sides

2x > 12          divide both sides 2

x > 6

So, the solution of the inequality 2x - 7 > 5 ⇒ x ∈ (6 , ∞)

The solution for the compound inequality will be:

(-∞ , 1] ∩ (6 , ∞) = ∅

See the attached figure.

Hi can someone help me with the top question I will mark u brainliest
Zanzabum

Answer:

1/16

Step-by-step explanation:

Find the common denominator between 3/4, 1/8, and 1/16. 3/4 and 1/8 denominator can be 16. Then we have to make their denominator the same so multiply 3/4 with 4/4 and multiply 1/8 with 2/2:

3/4 + 1/8 + 1/16 = 12/16 + 2/16 + 1/16 = 15/16

now canola oil is the only thing left to find so that means:

16/16 - 15/16 = 1/16

A triangular pane of glass has a height of 30 inches and an area of 270 square inches. what is the length of the base pane
Tems11 [23]
The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.

To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.

The divisor of 0.004 is almost zero. What does this tell you about the quotient?
nasty-shy [4]

Answer:

  Its magnitude will be larger than 0.004.

Step-by-step explanation:

When a divisor is less than 1, the quotient will be greater than the dividend.

When the divisor is "almost zero", the quotient will be much greater than the dividend. Here, the dividend may be considered to be "almost zero", so we cannot say anything about the actual quotient except to say its magnitude will be greater than the dividend.

_____

The dividend is positive, so the quotient will have the same sign as the divisor. (Negative divisors can be "almost zero," too.)
