The slope is 5. The slope of a line parallel to this equation will be 5, regardless of its position.

To find the line that goes through the point (3,5) that has slope = 5.

y = 5x + b

now use the point to find 'b'

5 = 5(3) + b

b = -10

perpendicular: [tex]\frac{1}{2}[/tex]

[tex]y-0.5= \frac{1}{2} \times(x + 0.5)[/tex]

[tex]y - 0.5 = \frac{1}{2}x + 0.25[/tex]

[tex]y = \frac{1}{2}x+\frac{3}{4}[/tex]

What is Slope?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

The slope of the line is 1/3

First we have to choose two points from the graph

The first point = (1, -5)

The second point = (7, -3)

The slope of the line is the change is y coordinate with respect to the change in x coordinate of the function

The slope of the line m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Where m is the slope of the line

[tex](x_1,y_1)[/tex] is the coordinate of the first point

[tex](x_2,y_2)[/tex] is the coordinate of the second point

Substitute the values in the equation

The slope of the line = (-3 - (-5) / (7 - 1)

= (-3+5) / 6

= 2 / 6

= 1/3

Hence, the slope of the line is 1/3

If Salma sold 60 cups of lemonade with total 920 ounces, then the number of small cups is 10 and the number of large cups is 50.

The problem can be translated into a system of linear equations.

Let:

p = the number of small cups sold

q = the number of large cups sold

"Salma sold 60 cups"  can be translated into equation:

p + q = 60   (equation 1)

"totaling 920 ounces" can be translated into equation:

12p + 16q = 920  (equation 2)

Multiply equation 1 by 12 then substracted from equation 2:

12p + 16q = 920

12p + 12q = 720 _

          4q = 200

            q = 50

Substitute q = 50 into equation 1:

p + 50 = 60

p = 10

Hence, the number of small cups = 10, the number of large cups = 50.

The equation of line is y = 3x - 6

Define Equation of line.

          y - y₁ = m (x - x₁)  

We have the given points,

(1, -3) and (3, 3)

Let, (x₁ , y₁) = (1, -3)     and,

(x₂, y₂) = (3, 3)

Formula for equation of line is,

y - y₁ = m (x - x₁)

Where m is slope and for that we have formula for slope is

m =  (y₂ - y₁) / (x₂ - x₁)

plug in the values,

m = (3 - (-3) ) / (3 - 1)

m = 6 / 2

m = 3

Now, we get the slope. Now, just put the values in equation of line formula

y - y₁ = m (x - x₁)

y - (-3) = 3 (x - 1)

y + 3 = 3x - 3

y = 3x - 6

Hence, the equation of line is y = 3x - 6

Proved  that the line L and M are parallel lines

Here we have to prove that L and M are parallel

One angle at the point at F is given that 139 degrees

We know sum of angles on a straight line is 180 degrees

Then the other angle will be

139 + a = 180

a = 180 - 139

a = 41 degrees

Now consider the triangle and find the value of x

The sum of interior angles of a triangle is 180 degrees

then

(3x+8) + (3x) + (9x+7) = 180

3x+8 +3x +9x + 7 = 180

15x + 15 = 180

15x = 180 - 15

15x = 165

x = 165/15

x  = 11

Then the value of angle 3x +  8 = 3 × 11 + 8

= 33 + 8

= 41 degrees

Before that we have solved the angle at f = 41 degrees, therefore both are equal angles  which is called corresponding angles

Therefore, the line L and M are parallel

Hence, proved  that the line L and M are parallel lines

Step-by-step explanation:

The equation that could be used to find the measure of angle B is Sin B = √5/5.

According to the question,

We have the following information:

We have a right-angled triangle with all its sides given.

Now, in order to find the measurement of angle B, we will use trigonometric functions. Two functions Sin and Cos are given in options. So, we will find the values of angle B using these two.

Cos B = AB/BC

Cos B = 6/3√5

Cos B = 2/√5

Now, multiplying both the numerator and denominator by √5:

Cos B = 2√5/5

Now, this equation is not given in options. So, we will find the angle using Sin.

Sin B = AC/BC

Sin B = 3/3√5

Sin B = 1/√5

Now, multiplying both the numerator and denominator by √5:

Sin B = √5/5

Hence, the correct option is B.

The probability of a student playing a sport but not playing an instrument is around 0.4286.

The likelihood of a student not playing an instrument, provided they play a sport, is:
[tex]Probability=\dfrac{Number\ of\ students\ who\ play\ a\ sport\ but\ do\ not\ play\ an\ instrument​}{Number of \students\ who\ play\ a\ sport}[/tex]

It is known that 14 students participate in a sport, while 8 students do not engage in either a musical instrument or a sport. Thus, the number of students who play a sport but do not play an instrument is:

Number of students who play a sport but do not play an instrument = 14- 6
                                                                                                                 = 6
Now, let's calculate the probability:

Step-by-step explanation:

5.  The number line shows both hours and days.  It does not indicate why the relationship exists.  Perhaps the hours are the ones worked in a day.  What’s important is whether the relationship between the two is the same for all data pairs.  E.g., 12/2 = 6; 36/6 = 6; 60/6 - 5, and so forth.  They are all the same ratio, or rate: (6 hours)/(1 day)

The domain of this function c(x) = 14x + 13 using interval notation is (0, ∞).

The range of this function c(x) = 14x + 13 using interval notation is (13, ∞).

In Mathematics, the horizontal portion of any graph is used to represent all domain values and they are both read and written from smaller to larger numerical values, which simply means from the left of any graph to the right.

Additionally, the vertical extent of any graph represents all its range values and they are always read and written from smaller to larger numerical values, and from the bottom of a graph to the top.

By critically observing the graph of this function shown in the image attached below, we can reasonably infer and logically deduce the following:

The Recursive formula for the given explicit formula is u(1) = 1 and u(n+1) = u(n) + 4 , for n = 1 , 2 , 3 ....  , the correct option is (b) .

In the question ,

it is given that ,

the explicit formula is u(n) = 4n - 1 .

and u(n) = 1 ,

we need to find the recursive formula ,

We substitute n + 1 in place of n , in the equation u(n) = 4n - 1

after substitution , we get

u(n+1) = 4(n + 1) - 1

u(n+1) = 4n + 4 - 1

u(n+1) = 4n + 3

Subtracting u(n) = 4n - 1 from u(n+1) = 4n + 3  ,

we get

u(n+1) - u(n) = 4n + 3 - (4n - 1)

u(n+1) - u(n) = 4n + 3 - 4n + 1

u(n+1) - u(n) = 3 + 1

u(n+1) - u(n) = 4

u(n+1) = u(n) + 4

Therefore , The Recursive formula for the given explicit formula is u(1) = 1 and u(n+1) = u(n) + 4 , for n = 1 , 2 , 3 ....

The precise value of p is 4/18. Jae Hee's expected score in the game is 1.833. Jae Hee has a 1/162 chance of receiving a total score of -3. The likelihood that something will happen is defined as probability.

Therefore,

Value of p is,

∈p = 1

1/18 + p + 3/18 + 1/18 + 2/18 + 7/18 = 1

14/18 + p = 1

p = 4 / 18

So the exact value of p is 4/18

Expected score of the game :

∈(x) = ∈xi pi

= -3 (1/18) - 1 (4/18) + 0 (3/18) + 1 (1/18) + 2 (2/18) + 5 (7/18)

= 33/18

= 1.833

Expected score of the game Jae Hee plays is 1.833

Calculate Probability of Jae Hee getting total score of -3

p (total score -3 )

= p(x= -3) and p(x=0) + p(x=0) and p (x=3)

= 1/18 × 1/18 + 1/18 × 1/18

Step-by-step explanation:

The volume of the balloon after the addition of the extra gas is 11.87 liters

The initial volume of the balloon = 5.29 liters

Initial quantity of argon in the balloon = 2.51 mole

Here we have to use the unitary method

The volume of the 1 mole of argon = The initial weight  of the balloon / Initial quantity of argon in the balloon

Substitute the values in the equation

The volume of the 1 mole of argon = 5.29 / 2.51

= 2.11 liters

Additional argon added = 2.51 mole

Total quantity of argon = 2.51 + 3.13

= 5.64 mole

The volume of the 5.64 mole of argon = 5.64 × 2.11
