Which pair of angles in the figure below are vertical angles

Answer:

Decay

Step-by-step explanation:

The value, y of an investment x is given by:

y = 25000(1.16)^-x

x = number of month after investment

y = value of investment after x months

The function f(y) above is an exponential usually related in the form:

y = Ar^-x

Plugging values of x into the function :

After 1 month; x = 1

y = 25000(1.16)^-1 = 21551.724

After 2 month; x = 2

y = 25000(1.16)^-2 = 18579.072

After 3 month; x = 3

y = 25000(1.16)^-3 = 16016.441

Since y is decreasing with increasing value of x, then we have a decay

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

Answer:

-6

Step-by-step explanation:

3(-4) = -12

-2(-3)= 6

-12+6= -6

Answer:

-6

Step-by-step explanation:

If x = -4 and y = -3, the equation should be set up like this: 3(-4) - 2(-3). The rule is if you multiply a 1 positive number by 1 negative number, the answer will be negative.

3(-4) = -12

2(-3) = -6

Then, once you figure out the multiplication, finish up the equation by subtracting.

-12 - (-6) = -6

Step-by-step explanation:

(0.4y - 3)/(1.5y + 9) = -7/5

Cross multiply:

2y - 15 = -10.5y - 63

12.5y =  -48

y = -3.84

Answer:

8). TN = 22 units ; 9). √165

Step-by-step explanation:

The circumcenter of a triangle is the point in the plane equidistant from the three vertices of the triangle.

8). 6x - 56 = 3x - 17

3x = 39

x = 13

TN = 22 units

9). 4x - 17 = x + 10

3x = 27

x = 9

TN = 19

RT = [tex]\sqrt{TN^2 - RN^2}[/tex]

RT = [tex]\sqrt{361-196}[/tex] = √165 ≈ 12.8 units

Applying the properties of circumcenter of a triangle and the Pythagorean Theorem, the measure of each given segments are calculated as:

8. TN = 22

9. RT = 12.8

Recall:

8. Find TN

Given,

Thus,

6x - 56 = 3x - 17 (MT = TN = TP, because they are equidistant from the circumcenter, T.)

6x - 3x = 56 - 17

3x = 39

x = 13

TN = TP = 3x - 17

TN = 3x - 17

TN = 3(13) - 17

TN = 22

9. Find RT

Given,

Thus,

4x - 17 = x + 10 (TN = TP)

4x - x = 17 + 10

3x = 27

x = 9

TN = 4x - 17

TN = 4(9) - 17

TN = 19

To find RT, apply the Pythagorean Theorem

[tex]RT = \sqrt{TN^2 - RN^2}[/tex]

[tex]RT = \sqrt{19^2 - 14^2}\\\\\mathbf{RT = 12.8}[/tex]

In summary, applying the properties of circumcenter of a triangle and the Pythagorean Theorem, the measure of each given segments are calculated as:

8. TN = 22

9. RT = 12.8

Answer: y = 4km + 2km*x

Step-by-step explanation:

We know that Madelyn already cycled 4km this year, so we start at that point.

Now, each time that she goes to work, she cycles 2 km in total.

Now, if she does x trips to work, then she cycles 2km x times, this means that in total she would cycle 2km*x

if we also count the 4km she already has, we have the linear equation:

y = 4km + 2km*x

This is the equation we wanted to get.

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:

[tex]2x^2+5x-12=0[/tex]

Step-by-step explanation:

Algebra

To expand the given equation

[tex](2x-3)(x+4)=0[/tex]

we'll use the distributive property by multiplying each term of the first binomial by each term of the second binomial as follows:

[tex]2x^2+8x-3x-12=0[/tex]

Rearranging and simplifying:

[tex]\mathbf{2x^2+5x-12=0}[/tex]

Answer:

We conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:

[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

Step-by-step explanation:

Given the line

y+2x=4

converting into the slope-intercept form y = mx+b where m is the slope

y = -2x+4

comparing with the slope-intercept form

Thus, the slope is: m = -2

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -2

The slope of the new line perpendicular to the given line = – 1/m

                                                                                                = -1/-2 = 1/2

Using the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 1/2 and the point (-3, 5)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=\frac{1}{2}\left(x-\left(-3\right)\right)[/tex]

[tex]y-5=\frac{1}{2}\left(x+3\right)[/tex]

Add 5 to both sides

[tex]y-5+5=\frac{1}{2}\left(x+3\right)+5[/tex]

[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

Therefore, we conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:

[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]
