What is the solution set of [1/x-2]<-2
slavikrds [6]

Step-by-step explanation:

1 \div (x - 2) + 2  < 0

(1 + 2x - 4) \div ( x- 2) < 0

(2x - 3)  \div (x - 2) < 0

Hence

You have to put:

2x  - 3 > 0

And

x - 2 > 0

Which results in:

x > 3 \div 2

And

x > 2

The solution is:

3 \div 2 < x < 2

Look at the graph of the linear function. On a coordinate plane, a line goes through 4 points. Point A is (negative 2, negative
kondor19780726 [428]

Using it's concept, the rate of change between point C and point D is of 2.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the <u>change in the output divided by the change in the input</u>. Hence, over an interval [a,b], the rate is given as follows:

r = \frac{f(b) - f(a)}{b - a}

Considering the points of the given linear function, we have that:

  • Point C: f(1) = 2.
  • Point D: f(2) = 4.

Hence the rate of change between point C and point D is given by:

r = (4 - 2)/(2 - 1) = 2.

2/3* (1/3+3 1/4 help pls now
ale4655 [162]

Answer:

43/18

Step-by-step explanation:

2/3(1/3+ 3 1/4)

  • First solve parenthesis.

2/3(1/3+ 3 1/4)

find the lowest common denominator (12) to add the two fractions.

1/3= 4/12;  

3 1/4= 13/4 = 39/12

4/12+ 39/12= 43/12

2/3(43/12)

  • Then multiply the fractions.

2/3(43/12)

Numerator: 2*43= 86

Denominator: 3*12= 36

86/36

  • Last simplify your fraction.

43/18 or 2 7/18
