Answer:

y = 2x - 3

Step-by-step explanation:

We first need to find y, which is the slope of the line, in this case is 2/1 or 2. b is the y-intercept, or where the line crosses they y-axis, which here is -3. Now you have y = 2x - 3.

Answer:

Step-by-step explanation:

Simplifying

(2x + -3)(x + -4) = 0

Reorder the terms:

(-3 + 2x)(x + -4) = 0

Reorder the terms:

(-3 + 2x)(-4 + x) = 0

Multiply (-3 + 2x) * (-4 + x)

(-3(-4 + x) + 2x * (-4 + x)) = 0

((-4 * -3 + x * -3) + 2x * (-4 + x)) = 0

((12 + -3x) + 2x * (-4 + x)) = 0

(12 + -3x + (-4 * 2x + x * 2x)) = 0

(12 + -3x + (-8x + 2x2)) = 0

Combine like terms: -3x + -8x = -11x

(12 + -11x + 2x2) = 0

Solving

12 + -11x + 2x2 = 0

Solving for variable 'x'.

Factor a trinomial.

(3 + -2x)(4 + -1x) = 0

Subproblem 1

Set the factor '(3 + -2x)' equal to zero and attempt to solve:

Simplifying

3 + -2x = 0

Solving

3 + -2x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + -2x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + -2x = 0 + -3

-2x = 0 + -3

Combine like terms: 0 + -3 = -3

-2x = -3

Divide each side by '-2'.

x = 1.5

Simplifying

x = 1.5

Subproblem 2

Set the factor '(4 + -1x)' equal to zero and attempt to solve:

Simplifying

4 + -1x = 0

Solving

4 + -1x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + -1x = 0 + -4

Combine like terms: 4 + -4 = 0

0 + -1x = 0 + -4

-1x = 0 + -4

Combine like terms: 0 + -4 = -4

-1x = -4

Divide each side by '-1'.

x = 4

Simplifying

x = 4

Solution

x = {1.5, 4}

Answer:

P(E or F)=P(E)+P(F)=0.41+0.47=0.88

As per the probability of an event, the probability P(E or F) is 0.88, when E and F are mutually exclusive.

"Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes how likely they are.

Probability is the branch of mathematics concerning numerical 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. "

Given, the probability of the event E is P(E) = 0.41

The probability of the event F is P(F) = 0.47

Now, the probability P(E or F) is

= P(E) + P(F)

= 0.41 + 0.47

= 0.88

Therefore, P(E or F) = 0.88

Answer:

[tex]36[/tex]

Step-by-step explanation:

Given

[tex]x^2 - 12x = 21[/tex]

Required

Make a perfect square

First, get the coefficient (k) of x

[tex]k = -12[/tex]

Divide by 2

[tex]\frac{k}{2} = \frac{-12}{2}[/tex]

[tex]\frac{k}{2} = -6[/tex]

Square this result:

[tex](\frac{k}{2})^2 = (-6)^2[/tex]

[tex](\frac{k}{2})^2 = 36[/tex]

Hence, 36 when added to the left-hand side makes it a perfect square trinomial

Answer:

Verduras= $100

Lacteos= $60

Menestras= $120

Frutas y verduras= $80

Limpieza= $40

Step-by-step explanation:

Presupuesto= $400

Primero determinamos la proporción a gastar en cada rubro:

Verduras= 0.25

Lacteos= 0.15

Menestras= 0.3

Frutas y verduras= 0.2

Total= 0.9

Limpieza= (1 - 0.9) = 0.1

Ahora, la cantidad de dinero:

Verduras= 0.25*400= $100

Lacteos= 0.15*400= $60

Menestras= 0.3*400= $120

Frutas y verduras= 0.2*400= $80

Limpieza= 0.1*400= $40

Total= $400

- Cavaleri's Principle

Answer:

y = -2x - 4

Step-by-step explanation:

In order to write down the equation of this line in slope-intercept form we will need to know the slope and the y intercept. Since the y intercept is the value of y when x = 0, from this we know that in our case the y intercept is - 4. Now in order of find the slope we can choose any two points on the linear function and then divide the rise by the run of the slope (if you want to understand this more you can read about how to find the slope). In our case I took two points (-2, 0) and (0, -4). Form here we know that the slope is....

Let "m" be the slope...

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1} }= \frac{-4 - 0}{0 + 2} = \frac{-4}{2} = -2[/tex]

We know that the slope-intercept looks like y = mx + b (where m is the slope and b is the intercept) so since we know both the slope and the y interest we can conclude the following.

The equation of the linear function show is y = -2x - 4

Answer:

4.969696 hours

Step-by-step explanation:

The distance traveled is shown through the following equations

Distance = velocity * time

This means that

4100=velocity*4

This means that ariplane 1 travles at 1025 km/hr

We can then subtract 200 from this to find that airplane two travels at a speed of 825 km/hr

Now we need to find how long it takes for that plane to travel 4100

So using the same equation

4100=825*time

Divison will tell us that the answer is around 4.9696 hours which is pretty much 5

Answer:

The equation of the straight line in point-slope form

                            [tex]y - 4 = \frac{7}{9} (x-0)[/tex]

The equation of the straight line

                         7x -9y +36 =0

Step-by-step explanation:

Step(i):-

Given that the points (0,4) and (-9,-3)

The slope of the line

         [tex]m = \frac{y_{2} - y_{1} }{x_{2}- x_{1} } = \frac{-3-4}{-9-0} = \frac{7}{9}[/tex]

Step(ii):-

    Equation of the straight line passing through the point (0,4) and having slope m = 7/9

          [tex]y - y_{1} = m (x-x_{1} )[/tex]

         [tex]y - 4 = \frac{7}{9} (x-0)[/tex]

      9 y - 36 = 7x

              9y = 7x + 36

          [tex]y = \frac{7x}{9} +\frac{36}{9}[/tex]

Slope - intercept form  

                            [tex]y = \frac{7x}{9} +4[/tex]

Final answer:-

The equation of the straight line in point-slope form

                            [tex]y - 4 = \frac{7}{9} (x-0)[/tex]

The equation of the straight line

                         7x -9y +36 =0

Answer:

n = 11

Step-by-step explanation:

The side length of a triangle are n,n-3 and 2(n-2).

The perimeter of the triangle, P = 37 units

We need to find the value of n.

Perimeter = sum of all sides

n+n-3 +2(n-2) = 37

2n-3+2n-4 = 37

4n -7 = 37

4n = 37+7

4n = 44

n = 11

So, the value of n is 11.

Answer:

Y= -2x+4

Step-by-step explanation:

Put it in slope intercept form

y=mx+b

Now subtract 6x on both sides to get y isolated

3y=12-6x

Now divide 3 on both sides to get y by itself

y=4-2x

Now in slope intercept form is

y= -2x+4

Earnings per week for Amber = $200

Total increase in the salary as per Amber's hard work = 100%

To find:

Earnings of Amber now?

Solution:

We are given the initial salary and its percentage increase.

We have to find the increased value of salary.

Increase in the salary = 100% of $200

[tex]\Rightarrow \dfrac{100}{100}\times \$200\\\Rightarrow \bold{\$200}[/tex]

Amber's Current salary = Initial salary + Increase in the salary

Putting the values of the initial salary and increase in the salary:

Amber's Current salary = $200 + $200 = $400
