Answer:   A

Step-by-step explanation:

Answer:   [tex]3 \le x \le 5[/tex]

x is any real number between 3 and 5, including both endpoints

================================================

Explanation:

If A < B, then 1/A > 1/B. Applying the reciprocal flips the inequality sign.

For example, if 2 < 3, then 1/2 > 1/3. It might help to look at the decimal representations

1/2 = 0.500

1/3 = 0.333

We see that 1/2 is larger.

-----------

The inequality [tex]x < y < z[/tex] is the same as [tex]x < y \ \text{ and } \ y < z[/tex].

We've broken the single inequality into two smaller parts.

The given inequality breaks down into [tex]\frac{1}{6} \le \frac{1}{x+1}[/tex] and [tex]\frac{1}{x+1} \le \frac{1}{4}[/tex]

------------

Let's solve the first inequality for x

[tex]\frac{1}{6} \le \frac{1}{x+1}\\\\6 \ge x+1\\\\6-1 \ge x\\\\5 \ge x\\\\x \le 5[/tex]

Repeat for the other inequality as well

[tex]\frac{1}{x+1} \le \frac{1}{4}\\\\x+1 \ge 4\\\\x \ge 4-1\\\\x \ge 3\\\\[/tex]

-------------------------

We found that [tex]x \ge 3 \ \text{ and } \ x \le 5[/tex]

This is the same as [tex]3 \le x \ \text{ and } \ x \le 5[/tex] which combines to [tex]3 \le x \le 5[/tex]

Answer:

f(-2) =2

Step-by-step explanation:

f(-2) means we want the y value when x = -2

When x = -2 the function has a y value of 2

f(-2) =2

Hello.

The greater the negative number, the smaller (in value) it is.

-5/6 = -0.83

-0.83 (-5/6) < -0.94

Answer:

u<19

Step-by-step explanation:

70 > 3u+13

you subtract 13 to both sides

which will give you 57

then you divide 3 and 57

leaving you of with 19

so your answer will be u<19

Answer:

Step-by-step explanation:

x + 64 > = 120 (thats a greater then or equal sign)

x > = 120 - 64

x > = 56...he needs to collect at least 56 more

Answer:

x=7

Step-by-step explanation:

since the two angles are equal, set them equal to each other and solve for x

7x+35=84

subtract 35 from both sides

7x=49

divide both sides by 7 to isolate x

x=7

Answer:

<6 = 68

Step-by-step explanation:

<5 + <6 + 90 = 180  since the 3 angles form a straight line

22 + <6 + 90 =180

Combine like terms

112+ <6 = 180

Subtract 112 from each side

<6 = 180-112

<6 =68

Answer:

An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.

Step-by-step explanation:

An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.

Now, the conditions for which an equation will be called a perfect square trinomial are;

i) It is of the form: ax² + bx + c

I) It satisfies the condition: b² = 4ac.

Thus, the perfect square formula could take the following forms:

(ax)² + 2abx + b² = (ax + b)²

Or

(ax)² − 2abx + b² = (ax − b)²

There aren't any instructions so my best guess is that you draw a line from the ball to a zombie and then to another zombie, etc until all of the zombies are wiped out by the ball.

Answer:

its -3/8

Step-by-step explanation:

Answer:

The expected value of the proposition is -$0.76.

Step-by-step explanation:

It is provided that a basketball player has made 291 out of 389 free throws.

Then rate of him making a free throw is,

[tex]P(\text{free throw})=\frac{291}{389}=0.7481[/tex]

The probability that he makes the next 2 free throws is:

[tex]P(\text{Next 2 free throws})=(0.7481)^{2}=0.5596[/tex]

The payout rules are:

Compute the expected value of the proposition as follows:

Expected value = $38 × P (Makes both) + (-$50) × P (Misses both)

                          [tex]=($38\times 0.5596)+(-$50\times (1-0.5596))\\=21.2648-22.02\\=-0.7552\\\approx -$0.76[/tex]

Thus, the expected value of the proposition is -$0.76.

Answer:

the answer is -2

Step-by-step explanation:

LOGIC lol

i’ll try to break it down for u so u can understand a little better.

the horizontal line is X and the vertical line is Y.

if u start in the middle going horizontally to the right u can find X and X will = 2

to find Y u need to start in the middle and count upwards until you find where the lines meet to create a point. Y = 1

X/Y = 2/1 which can simplify to 2

But since the line is going from left to right and going downwards it is negative hope this helped :)

Answer:

72 lots

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Answer:

False.

Step-by-step explanation:

In truth, an inequality is a statement marked by any of these signs:

< less than

> greater than

[tex]\leq[/tex] less than or equal to

[tex]\geq[/tex] greater than or equal to

For example, if I wrote x < y. This means that x must always be less than y. Now, if I wrote c [tex]\geq[/tex] d, this means that c can be greater than OR equal to d. If you see a line under one of these signs, it means (sign) or equal to. So at times, they can be equal, but not strictly. That would be an equation.
