Step-by-step explanation:

The value of the variable x, of the linear equation 5x 8 − 3x = −10 is -9, which is obtained after solving it. Option 1 is the correct option.

A linear equation is the equation in which the highest power of the unknown variable is one.

Here, the given linear equation is,

[tex]5x +8 - 3x = -10[/tex]

Solve it by arranging the equation as,

[tex]5x - 3x +8= -10\\2x+8=-10[/tex]

Subtract number 8 both side of the equation as,

[tex]2x+8-8=-10-8\\2x=-18[/tex]

Divide both side of the equation with number 2 as,

[tex]x=\dfrac{-18}{2}\\x=-9[/tex]

Hence, the value of the variable x, of the linear equation 5x 8 − 3x = −10 is -9, which is obtained after solving it. Option 1 is the correct option.

For the given parabola, the axis of symmetry is x = 2.

For any given parabola, we define the axis of symmetry as a line that divides the parabola in two equal halves.

For a regular parabola, we define the axis of symmetry as:

x = h

Where h is the x-component of the vertex.

Remember that for the general parabola:

y = a*x^2 + b*x + c

The x-value of the vertex is:

h = -b/(2a)

Then for the function:

f(x)=−2x²+8x−2

We get:

h = -8/(2*-2) = 2

Then the axis of symmetry is x = 2.

Answer:

  a. 2 7/9 miles

  b. 21.6 minutes

  c. 8 1/3 miles

Step-by-step explanation:

The rate at which Catlin runs can be determined from the graph by finding the coordinates of a grid point that lies on the line. The line goes through the origin, so the relationship between time and distance is proportional.

We see that the point (miles, minutes) = (1 2/3, 12) lies on the graph, so the contant of proportionality is ...

  k = y/x = 12/(5/3) = 36/5 = 7.2 . . . . minutes/mile

__

The proportion can be written ...

  distance/(20 minutes) = (1 mile)/(7.2 minutes)

  distance = (20/7.2) miles = 2 7/9 miles

Catlin will run 2 7/9 miles in 20 minutes

__

The proportion can be written ...

  time/(3 miles) = (7.2 minutes)/(1 mile)

  time = (3)(7.2 minutes) = 21.6 minutes

Catlin was running 21.6 minutes

__

In 1 hour, Catlin will run 3 times as far as in 20 minutes. Using the result from part A, we find ...

  3(2 7/9 miles) = 8 1/3 miles 8 1/3 miles

Catlin will run 8 1/3 miles in one hour.

_____

Additional comment

Once we have a relationship between minutes and miles, we can write proportions with either of those numbers in the numerator or denominator. We find it convenient to put the unknown value in the numerator of a proportion, which is why the ratios are written differently in the different parts of the problem.

You can't, the only factor in both is 1

v = 6.8

Step-by-step explanation:

10 = 8v - 3 (v+8)

10 = 8v - 3v - 24

10 = 5v - 24

24 + 10 = 5v - 24 + 24

34 = 5v

5 ÷ 34 = 5v ÷ 5

Answer:

Step-by-step explanation:

Angles in a Triangle always add up to 180

So,  3(9x-12)=180

27x-36=180

216=27x

x=8

The angle of the equilateral triangle is 60° and x is 8.

A triangle is a polygon with three sides and three vertices.

The triangle's total number of angles comes to 180°.

Given, measure of angle of an equilateral triangle 9x-12.

The sum of all the angles of the triangle is 180°.

That means,

3(9x-12) = 180°

27x = 180+36

x = 216 / 27

x =8

Therefore, the value of x is 8.

The commutative property of addition is shown here a+bi+c+di = a+c+bi+di which is the correct answer.

The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the result.

This property applies to multiplication also.

We have the given expression:

a+bi+c+di = a+c+bi+di

We have to identify the property of addition in the above expression.

Since we can say here that (bi+c) is expressed as (c+bi).

The commutative property of addition states that the numbers can be added in any order.

Mathematically, it states that a+b = b+a.

Here, (bi+c) can be replaced by (c+bi), whether 'b' is added to 'ci' or 'ci' is added to 'b', the result is always the same.

Therefore, the commutative property of addition is the correct answer

The standard deviation is the maximum and the minimum variation in the data set from the mean. The value of the standard deviation is 1.5.

The standard deviation is the maximum and the minimum variation in the data set from the mean.

Given that the mean shoe size is 7.5, while the size of shoe for the entire class is only 1 deviation, and the value is 6 and 9. Therefore, the equation of the standard deviation and the mean can be written as,

[tex]\mu -\sigma < x < \mu +\sigma \\6 < x < 9[/tex]

Now, the value of the standard deviation can be written as,

[tex]\mu - \sigma = 6\\\\-\sigma = 6-7.5\\\\-\sigma = -1.5\\\\\sigma = 1.5[/tex]

or the value of the standard deviation can be written as,

[tex]\mu + \sigma = 9\\\\ \sigma = 9-7.5\\\\ \sigma = 1.5[/tex]

Hence, the value of the standard deviation is 1.5.

The probability that the first three cards that he deals are all hearts if none of them are replaced will be [tex]\rm P = \frac{13}{52} \times \frac{12}{51} \times\frac{11}{50}[/tex].

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.

Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

The given data in the problem is ;

Total number of the card in the deck = 52

No of hearts = 13

If one heart is taken out one at a time we will get the probability that the first three cards that he deals are all hearts if none of them are replaced

From the total card one by one the cards is taken out without the replacement;

Without replacement, the card will be reduced by 1Also the heart card will also be decreased by one.

The probability that the first three cards that he deals are all hear will be;
