Given equation:

Multiply all terms by 7 to get rid of fraction:

Solving for the value of x,

→ (3/7)x - (4/7) = -1/7

→ (3x - 4)/7 = -1/7

→ 3x - 4 = (-1/7) × 7

→ 3x - 4 = -1

→ 3x = -1 + 4

→ x = 3/3 = 1

Hence, the value of x is 1.

Answer:

y=5x+1.5

Step-by-step explanation:

First, we need to find the slope which is M

put B as 0 for now so we going to plug in 2 numbers on the same horizontal side

I'm going to use (-2 and 11.5) and (4 and -18.5), and now I'm going to do [tex]\frac{y^{2}-y^{1} }{x^{2} -x^{1} } \\[/tex] which -18.5-11.5/4-(-2)

I'm going to get 30/6 which means 5

the slope is 5 now we can find Y-intercept by plugging in a pair of Y and X and plug in M to find B

11.5=(5)-2+b

11.5=10+b now we going to separate b by subtracting 10 from both sides

1.5=b

it hard to tell what you are saying, but if we know what the other number is, then expression.

Answer: Where are the tables?

Answer: Equation using slope intercept from y= -(5/2)x +26

Step-by-step explanation:

Write an equation of the line (in slope-intercept form) that is perpendicular to the line y=(2/5)x-(1/5) and contains the point (-4,16).

The line given is y=(2/5)x-(1/5)

Which we can rewrite in y= mx+b form as

y=(2/5)x-(1/5)

So slope of this line is (2/5)

A line perpendicular will have slope = -(5/2) ,  Which is (1/m)

Equation of new line will be

y = -(5/2)x +b

Now we need to find b

Plug in Point (-4,16)

Replace with the (-4,16) values

16 = (5/2) (-4) +b

solve it, 16=(-10)+b

16+10=b

b=26

Using some logarithmic properties, we will see that the solution of the logarithmic equation is 10.5

Here we have some properties that you need to remember.

log(A*B) = log(A) + log(B)

log(A/B) = log(A)  - log(B)

log(Aⁿ) = n*log(A)

Then we can rewrite our equation as:

[log(x²) + log(√z)] - log(y³)

Now, remember that a square root is equal to an exponent of 0.5, then:

[log(x²) + log(√z)] - log(y³) = 2*log(x) + 0.5*log(z) - 3*log(y)

Now we can replace the logarithms by the given values:

2*log(x) + 0.5*log(z) - 3*log(y)

2*7 + 0.5*5 - 3*2 = 10.5

The solution of the logarithmic equation is 10.5

A perpendicular bisector can be defined as a line that intersects another line segment perpendicularly and divides it into two parts of equal measurement. We can draw a perpendicular bisector using a rule, a compass and a pencil.

Two lines are said to be perpendicular to each other when they intersect each other at 90 degrees or at right angles. And, a bisector is a line that divides a line into two equal halves. Thus, a perpendicular bisector of a line segment AB implies that it intersects AB at 90 degrees and cuts it into two equal halves.

A line segment that bisects another line segment at a 90° angle is known as a perpendicular bisector. In other words, a perpendicular bisector divides a line segment into two equal parts by intersecting it at a 90° angle.

Probability are important information when applying descriptive statistics. Probability is the branch of mathematics concerning numerical descriptions. the correct option is (B).

Descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur.

here, we have,

A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%).

The probability formula defines the likelihood of the happening of an event. It is the ratio of favorable outcomes to the total favorable outcomes. The probability formula can be expressed as,

Probability formula:

P(A) = Probability(Event) = Favorable Outcomes/Total Outcomes

P(A) =   x/n

where,

P(B) is the probability of an event 'B'.

n(B) is the number of favorable outcomes of an event 'B'.

n(S) is the total number of events occurring in a sample space

Descriptive statistics are brief informational coefficients that summarize a given data set, which can be either a representation of the entire population or a sample of a population. Descriptive statistics are broken down into measures of central tendency and measures of variability (spread). Measures of central tendency include the mean, median, and mode, while measures of variability include standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.

The main purpose of descriptive statistics is to provide information about a data set. In the example above, there are hundreds of baseballs players that engage in thousands of games. Descriptive statistics summarizes the large amount of data into several useful bits of information.

The value of w in terms of x is w = 16/√x

From the question, we are to find w in terms of x

From the given information,

w is proportional to square root of y

That is,

w ∝ √y

∴ w = k√y

Where k is the proportionality constant

and

y is inversely proportional to x

That is,

y ∝ 1/x

y = c/x

Where c is the constant of proportionality

From the information, we have that

When x = 4, y = 16 and w = 8

From w = k√y

8 = k√16

8 = k×4

k = 8/4

k = 2

Also,

y = c/x

16 = c/4

c = 16 × 4

c = 64

Now, we are to write w in terms of x

w = k√y and y = c/x

∴ w = k√(c/x)

w = 2√(64/x)

w = 2 × √64 / √x

w = 2 × 8/√x

w = 16/√x

Hence, the value of w in terms of x is w = 16/√x

[tex]x=\frac{1}{2}[/tex]   or 0.5 in decimal form

Step-by-step explanation:

The expression is [tex]\frac{x+1}{x-2}-\frac{x-3}{x+2}=0[/tex]

Find Least Common Multiplier (LCM) of the denominators [tex]x-2,\:x+2[/tex]

This is [tex](x-2)(x+2)[/tex]   the product of the two denominators

Multiply entire equation by this LCM: [tex](x-2)(x+2)[/tex]

We get

[tex]\frac{x+1}{x-2}\left(x-2\right)\left(x+2\right)-\frac{x-3}{x+2}\left(x-2\right)\left(x+2\right)=0\cdot \left(x-2\right)\left(x+2\right)[/tex]

Simplify the first term

[tex]\frac{x+1}{x-2}\left(x-2\right)\left(x+2\right)[/tex]  [tex]=\left(x+1\right)\left(x+2\right)[/tex]

Simplify the second term

[tex]-\frac{x-3}{x+2}\left(x-2\right)\left(x+2\right) =\quad -\left(x-3\right)\left(x-2\right)[/tex]

RHS is [tex]0[/tex]

Therefore we get

[tex]\left(x+1\right)\left(x+2\right)-\left(x-3\right)\left(x-2\right)=0[/tex]

Expand the first term using the FOIL method [tex](x+a) (x + b) = x^2 + ax + bx + ab[/tex]

Here a = 1, b = 2. So [tex](x+1)(x+2) = x^2 + 2x + 1x + (1)(2) = x^2 + 3x + 2[/tex]

[tex]\left(x+1\right)\left(x+2\right)[/tex][tex]=x^2+3x+2[/tex]  

Expanding [tex]-\left(x-3\right)\left(x-2\right)[/tex] gives us [tex]-x^2 + 5x - 6[/tex]

(Use the FOIL method: [tex](x+b) (x + a) = x^2 + ax + bx + ab[/tex]  Here a = -2, b = -3. Note there is a negative sign before the entire expression)

So the original expression is

[tex]x^2+3x+2-x^2+5x-6 = 0[/tex]

Collecting like terms

[tex]x^2-x^2 + 3x +5x + 2 - 6[/tex] [tex]= 8x -4[/tex] = [tex]0[/tex]

Add 4 to both sides

[tex]8x-4+4=0+4[/tex]
