Which lines are parallel to the graph of 4x – y = 6? Check all that apply.

x – 4y = –12
y – 2 = –4(x + 1)
y + 1 = 4(x – 2)
y = 4x + 11
y = x – 3
8x – 2y = 6

The equation of the line y = 4.2x + 7.9 expressed in standard form is 42x - 10y = -79.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Given the equation of a line, multiply both sides by 10 to turn the decimals into integers.

y = 4.2x + 7.9

10y = 10(4.2x + 7.9)

10y = 42x + 79

Rewriting it in standard form ax + by = c,

10y = 42x + 79

42x - 10y = -79

The likelihood that a five-card poker hand will contain a flush (five cards of the same suit). = 0.001981

Probability is extremely important in everyday life. Weather forecasting, sports as well as gaming strategies, purchase or sale of insurance, online shopping and online games, blood group determination, and political strategy analysis

A standard deck of cards contain 52 cards. A five - card poker hand select 5 of the 52 cards.

C(52 , 5) = [tex]\frac{52 !}{5 !(52-5) !}[/tex]

              = 52!/(5!47!)

             = 2,598,960

Number of hand contenting a flush:

we need to select 1 of the 4 suits and then select 5 of the 13 cards from this suit.

C(4 , 1) = [tex]\frac{4 !}{1 !(4-1) !}[/tex]

           = 4!/(1!3!)

           = 4

C(13 , 5) = [tex]\frac{13 !}{5 !(13-5) !}[/tex]

             = 13!/(5!8!)

              = 1287

Using the product rule:

4*1287 = 5148

Probability:

5148 of the  2,598,960 hands will contain a flush.

The probability is calculated by dividing the number number favorable outcomes by the total number of possible possibilities.

P = 5148/ 2,598,960

= 33/16660

the likelihood that a five-card poker hand will contain a flush (five cards of the same suit). = 0.001981

The line which have a steeper slope is Line 1.

It is given in the question that the points on the line are given by:-

Line 1: (0,-4) and (2,2)

Line 2:(0,-4) and (4,5)

We have to find which line has a steeper slope.

First we will find the slope of each line.

We know that slope of a line with points (a,b) and (c,d) is given by:-

(d-b)/(c-a)

Slope of Line 1:

(2-(-4))/(2-0) = 6/2 = 3

Slope of Line 2:

(5-(-4))/(4-0) = 9/4 = 9/4 = 2.25

We know that greater the slope of the line means greater the steep of the line.

As,

Hence, Line 1 is steeper than Line 2.

Angle ∠ABC and angle ∠CDE are supplementary angles. Then the value of the variable x will be 18°.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

From the figure, the angle ∠ABC and angle ∠CDE are supplementary angles. Then we have

∠ABC + ∠CDE = 180°

2x + 8x = 180°

10x = 180°

x = 180° / 10

x = 18°

Then the value of the variable x will be 18°.

Answer:

Profit = $216

Step-by-step explanation:

To solve this, let's first calculate the amount she spent buying 38 shirts at $7 each:

• total spent = 38 × 7

                    = $266

We are told that she then sold 31 shirts at $16 each. Using this information, let us now calculate the total amount she earnt selling these shirts:

• total earnt = 31 × 16

                    = $496

Next, she returned 7 shirts and paid a $2 charge for each returned shirt. Therefore, the amount she spent on returning was:

• total spent returning = 7 × 2

                                     = $14

Therefore she earned a total of $496 and spent $266 and then $14. We can calculate her profit by subtracting the two expenditures from the earnings:

• Profit = $496 - $266 - $14

           = $216

Hence her profit was $216.

Chantel will take approximately 12.19 hours to complete the triathlon with the given speed of his.

Total distance covered for the race is:

For swimming = 2.4 miles

Speed of Chantel in swimming = 1.2 miles per hour.

So, time taken for completing the swimming part = 2.4 / 1.2 = 2 hours.

For bike ride = 112 miles

Speed of Chantel in bike riding = 18.8 miles per hour

So, time taken for completing the bike riding part = 112 / 18.8 = 5.96 hours.

For running = 26.2 miles

Speed of Chantel in running = 6.2 miles per hour.

So, time taken for completing the running part = 26.2 / 6.2 = 4.23 hours.

Total time = 2 + 5.96 + 4.23 = 12.19 hours.

Therefore, Chantel will take approximately 12.19 hours to complete the triathlon with the given speed of his.

The vertical translation equation of the given equation is y = 2x-(2/5). (First option)

You can do things with equations of the form y=f(x) that modify the graph in various ways.

Vertical movement means moving up and down the graph of a function. For example, you can move the chart up, down, left, or right, flip it around the x or y-axis, or stretch or shrink it vertically or horizontally. The form of the function remains the same, known as moving the chart along the Y axis.

Vertical translation translates each point on the graph by k units vertically and the graph/chart by k units vertically.

The given statement that A triangle with an angle that measures greater than 90° is a right triangle is a FALSE statement.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

A right-angle triangle is a triangle whose any one interior angle is 90°.

Let's say the remaining angles are x and y degrees.

The sum of all interior angles is 180 degrees.

So,

x + y + 90 = 180

x + y = 90

x = 90 - y ⇒ x ≤ 90°

y = 90 - x ⇒ y ≤ 90°
