Solve the rational inequality x-2/x + x+2/x+3 < 3/2 represent your answer using a number line and using interval notation

Mathematics

Firdavs [7]3 years ago
7 0

Answer and explanation:

To solve the inequality x-2/x + x+2/x+3 < 3/2 we have to first simplify the expressions on the left side of the inequality sign. And so we multiply x by the expressions on the left side to eliminate fractions:

=x(x-2/x)+x(x+2/x)+x(3)< 3/2

=x-2+x+2+3x < 3/2

=5x < 3/2

x < 3/2/5

x < 3/2×5/1

x < 15/2

x < 7 1/2 or 7. 5

slavikrds [6]

Answer:

-0.0526

Step-by-step explanation:

Let X be the random variable denoting the net gain(in dollars) for a single trial(one bet).

Assuming that each number in the wheel is equally likely, probability of the outcome being a victory is \frac{1}{38} and probability of failure is \frac{37}{38}. For a win, X takes value 35 and for a loss X takes value -1. So the model is,

P(X=35) = \frac{1}{38}

P(X=-1) = \frac{37}{38}

P(X=i) = 0 \;if\; i \neq 38, i\neq -1

The mean for one bet is E(X) = \sum xP(X=x) = 35\times\frac{1}{38} - 1\times\frac{37}{38} = -0.0526

A square base of a pyramid has the dimensions 5 yards by 5 yards. The height of one of the triangular faces is 12 yards. How can
-Dominant- [34]

Answer:

145 yards squared

Step-by-step explanation:

So the area of the base is area of a square with side length of 5 yards 5*5=25

The area of one triangular face base times height divided by two and then simply multiplied by 4 because there are 4 triangular faces.

(\frac{5*12}{2} )*4 = 120

So the total surface area is 25+120=145 yards squared

What is x equal to ? Link down below.
scZoUnD [109]

Answer:

50

Step-by-step explanation:

Because of supplementary angles that line has to equal to 180

180-75 = 105

so 105 = (2x + 5)

you can subtract 5 from each side and get

100 = (2x)

then divide each side by 2 and you get

x = 50

you can check it by doing (2 x 50 + 5)

2 x 50 = 100 + 5 = 105 + 75 = 180
