Answer:

Domain: -inf to inf

Range: -1, inf

Step-by-step explanation:

1) y = 6

2) x = 3

3) y = - 2/3

4) x = - 6

So all we have to do is substitute the known 'variable' and solve for the unknown variable.

1)    2(-3) + 3y = 12

                 3y = 12 + 6

                  y = 6

2)    4y = (1/3)x - 5

    4(-1) = (1/3)x - 5

   (1/3)x = 5 - 4

        x = 3

3)       (x/3) - 2 = y

    (4/3) - (6/3) = y

                    y = (-2/3)

4)   2(x+1) = 5y

     2(x+1) = 5(-2)

    2x + 2 = - 10

          2x = -12

           x = -6

Answer:

(- 3, - 7 )

Step-by-step explanation:

Given the 2 equations

y = 4x + 5 → (1)

y = x - 4 → (2)

Substitute y = 4x + 5 into (2)

4x + 5 = x - 4 ( subtract x from both sides )

3x + 5 = - 4 ( subtract 5 from both sides )

3x = - 9 ( divide both sides by 3 )

x = - 3

Substitute x = - 3 into either of the 2 equations and evaluate for y

Substituting into (2)

y = x - 4 = - 3 - 4 = - 7

solution is (- 3, - 7 )

There are 210 sequences for 7 church bells to rung with the given conditions. Using permutations, the required number of sequences is calculated.

A sequence or arrangement that can be framed by taking some or all of a finite set of things (or objects) is called a permutation.

The formula for finding the number of such arrangements is,

ⁿPₓ = n!/(n - x)!

It is given that, a church's bell tower has 7 bells. 3 of them will ring in a sequence before each service and no bell is rung more than once.

So, the number of sequences that the bells will form is calculated by using the permutations formula. I.e., ⁿPₓ = n!/(n - x)!

Here, n = 7; x = 3

Then,

ⁿPₓ = n!/(n - x)! ⇒ ⁷P₃ = 7!/(7 - 3)! = 7!/4!

⇒ ⁷P₃ = (7 × 6 × 5 × 4!)/4! = 7 × 6 × 5 = 210

Therefore, there are 210 sequences for ringing the bells.

The minimum number of choices in a scoring procedure that the student must eliminate before it is advantageous to guess among the rest is 4. Option E is the correct option.

Suppose that there are n choices remaining for a particular question.

The probability of answering this question correctly is 1/n if the student guesses and the probability of leaving the question unanswered is (n-1)/n.

The expected score for guessing is therefore (7/n) × (1/n) + (2/n) × ((n-1)/n) = (7 + 2(n-1))/n² = (9 - 2/n)/n.

The expected score for leaving the question unanswered is 2/n.

The student should guess if and only if the expected score for guessing is greater than the expected score for leaving the question unanswered.

That is, we must have (9 - 2/n)/n > 2/n, or equivalently 9 > 2n, or n < 4.5.

Thus, if the number of choices remaining is 4 or more, the student should not guess; if the number of choices remaining is 3 or fewer, the student should guess.

Answer:

  32°

Step-by-step explanation:

You want the measure of the smaller angle of the linear pair marked (3g+23) and (7g+127).

The angles of a linear pair total 180°, so we have ...

  (3g +23) +(7g +127) = 180

  10g = 30 . . . . . . . . . subtract 150

  g = 3 . . . . . . . . . divide by 10

The smaller angle is ...

Answer:

Robin, Raven, Turtle dove, Canada goose.

Step-by-step explanation:

We are given the size of the eggs.

Now, we need to put the sizes of eggs in ascending order.

=> \(\frac{17}{5},\frac{3}{4} ,\frac{6}{5} , \frac{10}{9}\)

Step 1: Make the denominators same.

=> \(\frac{17}{5},\frac{3}{4} ,\frac{6}{5} , \frac{10}{9}\)

=> \(\frac{612}{180} ,\frac{135}{180} ,\frac{216}{180}, \frac{200}{180}\)

Step 2: Order these egg sizes in ascending order.

=> \(\frac{612}{180} ,\frac{135}{180} ,\frac{216}{180}, \frac{200}{180}\)

Answer:

x = 3

Step-by-step explanation:

x+5=8

x+5-5=8-5

X=3

Answer:

x = 3

Step-by-step explanation:

basically 2 ways

1st: Transposing

1) x + 5 = 8

2) transpose or transfer +5 to the other side

NOTE: transposing numbers and variables switches the signs (positive -> negative and vice versa)

3) x = 8 - 5

x = 3

2nd: Property of Equality (whatever u do one one side, you do the same to the other)

1) x + 5 = 8

2) x + 5 - 5 = 8 - 5

x = 3

the main focus is to isolate x, or to make it be alone in one side of the equation

Answer:

C

Step-by-step explanation:

13+5=18 not 19 therefore C is not true

First off, we need the slope

\(\frac{y2-y1}{x2-x1}\)

\(\frac{8-(-4)}{1-(-2)}\)

That leaves you with

12/3 = 4

point-slope form: y-y1 = m ( x - x1)

So...

y - (-4) = 4 ( x - (-2))

y + 4 = 4 (x + 2)

y + 4 = 4x + 8

Now subtract 4 from both sides of the equation

y = 4x +4

Step-by-step explanation:

Question wants to know the number of Guides present on Sunday.

On Saturday there were 120 tourists and 18 guides. The ratio was therefore:

Answer:

6x-16

Step-by-step explanation:

The expression is equivalent to :

\(4x^2-6x-16\)

The difference is that expressions do not include an equal sign and are basically mathematical “phrases.” Equations include an equal sign, and show equivalency between two mathematical expressions. For example, 2x + b is an algebraic expression, but 2x + b = 14 is an algebraic equation.

The expression is given as:

\((6x^2-9x-24)\frac{2}{3}\)

Answer:

x = -25.

Step-by-step explanation:

If f(x) = 2x + 1, and g(x) = -5x + 2, then f(g(x)) = 2(-5x + 2) + 1 = -10x + 4 + 1 = -10x + 5.

Answer:

36

Step-by-step explanation:

I don’t know if this half the problem or something because you only need to know what a equals but...

1. Substitute x for 4 since x=4... so the equation would then be (4)^2+10(4)-20

2. You simplify so 4 squared is 16 because when you square something you times it by it self so 4^2 is simply 16 because 4*4=16 then 10*4 is 40 so then you get 16+40-20

3. So you can simplify that again to 56-20 and then to 36

The probability that the sample mean would be less than 132.25 liters is 0.0558.

The central limit theorem (CLT) of probability theory states that, under the assumption that all samples are of equal size and regardless of the population's actual distribution shape. The distribution of a sample variable approaches a normal distribution (i.e., a "bell curve") as the sample size increases.

Given, \(\mu\) = 138 , \(\sigma\)= 28

According to the central limit theorem,

P(\(\bar{x }\) < x) = P( Z < x - \(\mu\) / \(\sigma\) / \(\sqrt{n}\) )

So,

P( \(\bar{x }\)< 132.25 ) = P( Z < 132.25 - 138 / 28 / \(\sqrt{60}\) )

= P( Z < -1.5907)

= 1 - P( Z < 1.5907)

= 1 - 0.9442

= 0.0558

Step-by-step explanation:

Add the numeral numbers,2+3=5

then you can change 1/2 into 2/4

Add the fraction  1/4 + 2/4 = 3/4

The graph of the equation y = \(2^{x}\) - 5 is obtained by shifting the graph of

y =\(2^{x}\)  downside by 5 units.

To find a graph of equation y = \(2^{x}\) - 5, we can start with the reference of the parent function y = \(2^{x}\) and also apply the necessary transformations.  Initiating with the graph of the parent function y =\(2^{x}\) - 5.

This is an exponential function that passes through the point( 0, 1) and has a positive pitch. Apply the transformation -5 units over. This means we shift the entire graph over by 5 units. The point( 0, 1) will now come( 0,-4).thus, the graph of the equation y =  \(2^{x}\)- 5 is attained by shifting the graph of y =  \(2^{x}\) downcast by 5 units. The factual shape of the graph will act as that of the parent exponential function, but it'll be shifted over by 5 units.
