Answer:

y = 2x - 3

Step-by-step explanation:

The graph is a straight line, thus linear with equation

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, 3) and (x₂, y₂ ) = (6, 9) ← 2 points on the line

m = [tex]\frac{9-3}{6-3}[/tex] = [tex]\frac{6}{3}[/tex] = 2 , thus

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 3 ), then

3 = 6 + c ⇒ c = 3 - 6 = - 3

y = 2x - 3 ← equation relating x and y

The equation whigh relates x and y points on the graph can be expressed in slope-intercept form as y = 2x - 3

The general form of a slope - intercept equation is :

Slope, b = Rise / Run

Slope, b = 6/3 = 2

Taking a pair of point on the graph :

(3, 3)

3 = 2(3) + c

3 = 6 + c

3 - 6 = c

c = - 3

Therefore equation can be expressed thus :

Discontinuity is the value of x or y for which the function is not defined. The function is discontinued at points x=0 and x=4.

The discontinuity is the value of x or y for which the function is not defined. It is represented by a blank dot at the point at which it is not defined.

The discontinuity of the function is represented by a blank dot, and it is the point where the function is not defined.

If we look in the graph, we will find that there are three blank dots, which are at:

x = -2

x = 0

x = 4

Now, since discontinuity means that the function is not defined but as we can see that the value of the function is defined at x = -2, therefore, we are left with only two options which are x=0 and x=4.

Hence, the function is discontinued at points x=0 and x=4.

2/13

Step-by-step explanation:

So firstly, know that there are 13 cards in the deck (3 + 6 + 4).

Therefore, the probability of drawing a green is 4/13.

After you draw the green card, there will be 12 cards left. Therefore, the probability of drawing a purple card next is 6/12.

To find compound probability, multiply the probabilities of the two separate events happening together:

4/13 * 6/12

The factorisation of the polynomial [tex]2x^3+8x^2+3x+12[/tex] can be done as [tex](2x^2+3)(x+4)[/tex].

A factor of n is a number that when multiplied by another number gives us the number n.

In order to factorise the given polynomial, we need to take the common terms out, therefore, the factorisation of the given polynomial can be done as,

[tex]2x^3+8x^2+3x+12[/tex]

Take 2x² as the common term from the first two terms and 3 from the last two terms,

[tex]2x^3+8x^2+3x+12\\\\= 2x^2(x+4)+3(x+4)\\\\=(2x^2+3)(x+4)[/tex]

Hence, the factorisation of the polynomial [tex]2x^3+8x^2+3x+12[/tex] can be done as [tex](2x^2+3)(x+4)[/tex].

Answer: Look below.

Step-by-step explanation: To simplify this problem, you need to follow order of operations.

First you need to multiply (or divide, doesn't matter.)

Then you need to divide.

Lastly, you would subtract to get the answer of 6.

Use PEMDAS for order of operations.

Step-by-step explanation:

order of operations devide 12by 4 to get 3 and multiple the answer by 3 to9 and substract it from 15 to get 6

Answer:

The answer would be A) (-69, 15)

Solution:

Finding 1st and 2nd

m = (y2 - y1)/(x2 - x1)

m = (15 - 3 )/(6 - 3)

m = 12/3

y = 4x + b

3 = 3(3)+b

3=9+b

-9 -9

-6=b

Finding 3rd

repeat the above process for 1 and 2, so now use 2 and 3 in the equation.

m = -9/3

m=-3

y=-3x+b

15=-3(6)+b

b=-3

Hi!

To find the surface area, we must first find the area of all of the faces and then add them together.

Because every face is the same size, the formula will be:

6(8 x 8)

6 represents the number of faces and 8 x 8 represents the formula to find the area of each.

6(8 x 8) =

6(64) =

Answer:  Approximately 1.0714 gallons

===========================================

Work Shown:

x = amount of pure water

3 gallons of 95% alcohol means you have 3*0.95 = 2.85 gallons of pure alcohol.

If we add on x gallons of pure water, we'll have 3+x gallons of solution

So we'll have 2.85/(3+x) representing the ratio of the amount of pure alcohol to total solution. Set this equal to 0.70 and solve for x

2.85/(3+x) = 0.70

2.85 = 0.70(3+x)

2.85 = 0.70(3)+0.70(x)

2.85 = 2.10+0.70x

2.85-2.10 = 0.70x

0.75 = 0.70x

0.70x = 0.75

x = 0.75/0.70

x = 1.07142857142858 which is approximate

x = 1.0714

So if you add about 1.0714 gallons of pure water, you'll go from 95% alcohol to 70% alcohol.

Answer:

first of all we don't know where m is so I will give you all the degrees for all the angles so angle DAB is equals to 75 degrees angle ABC is equals to 105 degrees angle ADC is equals to 105 degrees

The measure of the angles ∠A will be 105°. Then the correct option is B.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezoid, one pair of opposite sides are parallel.

In the isosceles trapezoid, the sum of opposite angles will be equal to 180°. Then the equations are given as,

∠A + ∠C = 180°

Then the measure of the angle ∠A is calculated as,

∠A + 75° = 180°

∠A = 105°

The measure of the angles ∠A will be 105°. Then the correct option is B.
