2x+3=x-4
what is the solution of this equation?​

Answer:

-4

Step-by-step explanation:

So we are given the expression: | y - x | + y - 1, and we have our values for (x,y): (-3,-6).

So, we can just start plugging things in and simplifying, so:

| -6 + 3 | - 6 - 1 = | -3 | -7

                       = 3 - 7

                       = -4

Answer: The answer will be -4

Answer:

(a) The sample mean and sample standard deviation are 2.415 and 0.5342 respectively.

(b) Shown below.

Step-by-step explanation:

The data set provided is:

S = {1.75, 1.92, 2.62, 2.35, 3.09, 3.15, 2.53, and 1.91}

(a)

Compute the sample mean and sample standard deviation as follows:

[tex]\bar x=\frac{1}{n}\sum\limits_{i}{x_{i}} =\frac{1}{8}\times 19.32=2.415\\\\\\s=\sqrt{\frac{1}{n-1}\sum\limits_{i}{(x_{i}-\bar x^{2})^{2}}}=\sqrt{\frac{1}{8-1}\times 1.9976}=0.5342[/tex]

Thus, the sample mean and sample standard deviation are 2.415 and 0.5342 respectively.

(b)

Use SPSS to form a Box plot.

Go to Graphs → Legacy Dialogs → Boxplot

A dialog box will open.

Select "Simple".

The answer is 21.

First you Add both AB and BC which is 10x +14. Then you put 64 into the equation. 10x+14=64. Subtract 14 from 64 which is 50. So 10x=50. Then divide 10 from 50. which would be x=5. So if you plug it in. It would be 21.

Answer:

+-1, +-2,+-5, +-10

Step-by-step explanation:

you first find all the numbers that can go into the constant which is 10, so negative and positive 1 can go into 10, negative and positive 2 can go into 10 etc.

The possible rational roots of the polynomial equation

[tex]1,-1} , +\frac{1}{2} , -\frac{1}{2} , +2,-2, +5,-5, +\frac{5}{2} ,-\frac{5}{2} ,+10,-10[/tex]

Given :

The polynomial equation is

[tex]2x^{9}-3x^{7}+11x+10=0[/tex]

To find out possible rational roots, we use rational root theorem

Rational root of the form

[tex]\frac{p}{q}[/tex] where p is the constant and q is the leading coefficient

p=10  and q=2

Lets write all the factors of 10  and 2

Factors of 10 are 1,2,5,10

factor of 2 are 1,2

Rational root of the form

[tex]+- factors of \frac{p}{q} =+-\frac{1,2,5,10}{1,2}[/tex]

We consider both positive and negative factors. Ignore the repeated roots

So possible rational roots are

[tex]1,-1} , +\frac{1}{2} , -\frac{1}{2} , +2,-2, +5,-5, +\frac{5}{2} ,-\frac{5}{2} ,+10,-10[/tex]

Answer:

C

Step-by-step explanation:

x + 9 = 4(x-1)²

x + 9 = 4(x² - 2x + 1)                  Multiply (x - 1) times (x - 1)

x + 9 = 4x² - 8x + 4                  

4x² - 9x - 5 = 0                          Subtract x + 9 from both sides

Answer:

1/6 cups

Step-by-step explanation:

5/6 /5 = 5/6 divided by 5

= 5/6 x 1/5

= 1/6

so your answer is 1/6 cups of baking soda per tablespoon of water

yw ;)

The rate for cups of baking soda per tablespoon of water is 1/6.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The mixture that he adds to the paint is made of 5/6 cup baking soda for every 5 tablespoons of water.

Hence, The rate for cups of baking soda per tablespoon of water is,

⇒ 5/6 ÷ 5

⇒ 5/6 × 1/5

⇒ 1/6

Answer:

y = 4x + 9

Step-by-step explanation:

First, find the slope of the line, which is the change in y/the change in x:

(-11-1)/(-5-(-2)) = -12/-3 = 4

That leaves you with the equation:

y = 4x

But notice, when x = -2 in the equation, y = -8, but we want it to be 1, so we add 9 to the end of the equation:

y = 4x + 9

Answer:

The probability that they will teach different courses is [tex]\frac{2}{3}[/tex].

Step-by-step explanation:

Sample space is a set of all possible outcomes of an experiment.

In this case we will write the sample space in the form (x, y).

Here x represents the course taught by the first part-time instructor and y represents the course taught by the second part-time instructor.

Denote every course by their first letter.

The sample space is as follows:

S = {(P, P), (P, I), (P, S), (I, P), (I, I), (I, S), (S, P), (S, I) and (S, S)}

The outcomes where the the instructors will teach different courses are:

s = {(P, I), (P, S), (I, P),(I, S), (S, P) and (S, I)}

The probability of an events E is the ratio of the number of favorable outcomes to the total number of outcomes.

[tex]P(E)=\frac{n(E)}{N}[/tex]

Compute the probability that they will teach different courses as follows:

[tex]P(\text{Different courses})=\frac{n(s)}{n(S)}=\frac{6}{9}=\frac{2}{3}[/tex]

Thus, the probability that they will teach different courses is [tex]\frac{2}{3}[/tex].

Answer:

  2, 5, 6

Step-by-step explanation:

If we number the mixes 1-6 from top to bottom, then the fraction of the total that is yellow is ...

  1. 1/(3+1+2) = 1/6

  2. 2/(5+2+3) = 2/10 = 1/5

  3. 2/(6+2+4) = 2/12 = 1/6

  4. 4/(12+4+8) = 4/24 = 1/6

  5. 6/(15+6+9) = 6/30 = 1/5

  6. 8/(20+8+12) = 8/40 = 1/5

Mixes 2, 5, and 6 are the most yellow.   (1/5 > 1/6)

Answer:   point-slope form is [tex](y -y_{1} ) = m(x - x_{1} )[/tex]

9.5 -(-6) = 1/2(0-7)

Step-by-step explanation: You can get a y-intercept by substituting the x and y values from the given coordinate into the slope-intercept form and solve for b.

y = mx + b

-6 = 1/2(7) + b

-6 = 3.5 + b

-9.5 = b  Slope-intercept equation for this question would be  y = x/2 - 9.5

Then use the coordinates of the y-intercept to create the point-slope equation

(-9.5 -[-6]) = 1/2(0-7)
