Step-by-step explanation:

-4 is listed twice with 2 different outputs

Answer:

y=16.

Step-by-step explanation:

Using substitution requires us to substitute a value in place of another value. Luckily we are given the value of x and can use it in the second equation.

First, we substitute 4 for x.

y=2(4)+8

And then we simply solve.

y=2(4)+8

y=8+8

y=16

Answer:

1. CD = 6√3

2. AD = 18

3. ΔABC is an enlargement of ΔCBD by a scale factor of 2

4. 4 : 1

Step-by-step explanation:

The altitude of a triangle is the perpendicular line segment drawn from the vertex of the triangle to the side opposite to it.  

Therefore, line CD is an altitude

If an altitude is drawn from the right angle of any right triangle, then the two triangles formed are similar to the original triangle and all three triangles are similar to each other.

If two objects are similar, their corresponding angles are congruent (the same) and their sides are proportional in length.

Therefore, if m∠B = 60°  then  m∠C of ΔADC = 60°

If m∠A = 30° then m∠C of ΔCBD = 30°

This means that all triangles are 30-60-90 triangles.  30-60-90 triangles are special right triangles as the angles of these triangles are in a unique ratio of 1:2:3.  This means that the lengths of the sides is always in the ratio of 1 : √3 : 2  ⇒  y : y√3 : 2y

1.  Using the 30-60-90 triangle formula for sides:

    For ΔCBD:  CD = y√3,  CB = 2y,  DB = y

    We are told CB = 12  ⇒  2y = 12  ⇒  y = 6

    Therefore, CD = y√3 = 6√3

2.  Using the 30-60-90 triangle formula for sides:

    For ΔADC:  CD = y,  AC = 2y,  AD = y√3

    We know that CD = 6√3  ⇒  y = 6√3

    Therefore, AD = y√3 = 6√3√3 = 18

3.  Using the 30-60-90 triangle formula for sides:

    For ΔABC:  CB = y,  AB = 2y,  AC = y√3

    We know that CB = 12  ⇒  y = 12

    Therefore, AB = 24  and  AC = 12√3

Therefore, ratio of ΔABC : ΔCBD using the lengths of their hypotenuse:

24 : 12  ⇒  2 : 1

Therefore, triangle ΔABC is an enlargement of triangle ΔCBD by a scale factor of 2

4.  Area of a triangle = 1/2 x base x height

   ⇒  Area ΔABC = 1/2 x BC x AC = 1/2 x 12 x 12√3 = 72√3

   ⇒  Area ΔCBD = 1/2 x DB x CD = 1/2 x 6 x 6√3 = 18√3

    Therefore,  Area ΔABC : Area ΔCBD  ⇒  72√3 : 18√3  ⇒  4 : 1

Step-by-step explanation:

we calculate how much 0.3% is from 3280

y=3280*0.3/100=9.84$

months in 9y

12*9=108

the interest of 9y

108y=1062.72$

the sum of interest + the money borrowed

1062.72+3280=4342.72$

Answer:  Choice D

Fold the paper so that A is on top of B

Or vice versa

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

Explanation:

M is the midpoint of segment AB.

This means that segments AM and MB are the same length, by definition of what it means to be a midpoint.

We have symmetry going on about point M. When we fold the paper, we're introducing symmetry. Point M will be on the folding line, and the folding line is the perpendicular bisector of AB.

You can use the fact that left skewed distribution's graph will have upward values first like a mountain but leaned on left side and then plane low value or no values.

The distribution which is left skewed out of the given distributions is

Option D:  A graph shows the horizontal axis numbered 60 to 100. The vertical axis is numbered 1 to 3. The graph shows an upward then downward trend.

A skewed distribution is a distribution having bias on one of the two sides (either left or right).

It is like leaning mountain on one side(left or right).

A left skewed graph(also called negatively skewed graph) will have upward movement first (and fast) and then downward trend(slowly and sort of elongated)

A right skewed graph(also called positively skewed graph) will have downward movement first(slowly rising) and then upward trend(fast and abrupt like end on the right)

Thus,

The distribution which is left skewed out of the given distributions is

Option D:  A graph shows the horizontal axis numbered 60 to 100. The vertical axis is numbered 1 to 3. The graph shows an upward then downward trend.

Plantearemos una ecuación cuadratica, y resolviendola veremos que Federico tiene 21 años.

Lo primero que debemos hacer es definir la variable que vamos a usar, en este caso usare:

F = edad de Federico.

Dentro de 11 años, la edad de Federico será:

F + 11

Hace 13 años, la edad de Federico era:

F - 13

Reemplazando eso en lo que el problema plantea, tenemos:

(F + 11) = 0.5*(F - 13)^2

Ahora podemos resolver esto para F.

F + 11  = 0.5*(F^2 - 26*F +169)

F + 11 = 0.5*F^2 - 13*F + 84.5

Movemos todo al mismo lado:

F + 11 - 0.5*F^2 + 13*F - 84.5 = 0

-0.5*F^2 + 14*F - 73.5 = 0

Ahora tenemos una ecuación cuadratica, la cual resolvemos usando la formula de Bhaskara:

[tex]F = \frac{-14 \pm \sqrt{(14)^2 - 4*(-0.5)*(-73.5)} }{2*(-0.5)} =\frac{-14 \pm 7}{-1}[/tex]

Esto nos da dos valores:

El problema con el primer valor, es que es inconsistente con el enunciado, ya que en ese caso, Federico hace 13 años tendría una edad negativa. Así que descartamos la primer solución y nos quedamos con la segunda.

F = 21

Federico tiene 21 años.

Step-by-step explanation:

The quotient is (2x²+10x-5).

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Given

[tex]3x^4+6x^{2} +2x^{2} +9x+10[/tex] and [tex]x +2[/tex] polynomials.

The division of [tex]3x^4+6x^{2} +2x^{2} +9x+10[/tex] by [tex]x +2[/tex].

[tex]3x^4+6x^{2} +2x^{2} +9x+10[/tex] and [tex]x +2[/tex] polynomials are given.

[tex]3x^4+6x^{2} +2x^{2} +9x+10[/tex] satisfied by [tex]\rm x = -1,\ -2,\ 0.5,\ 0.5[/tex] . then

Then the equation become

(x+1)(x+2)(x-0.5)(x0.5) then divide the polynomial by x - 3.

[tex]\dfrac{3x^4+6x^{2} +2x^{2} +9x+10}{x+2} = \dfrac{(x+1)(x+2)(x-0.5)(x-0.5)}{x+2} \\\dfrac{3x^4+6x^{2} +2x^{2} +9x+10}{x+2} = (x+1)(x-0.5)(x-0.5)[/tex]

And on multiplication we have,

[tex](x+1)(x-0.5)(x-0.5) = (3^{3} +2x+5)[/tex]

Thus the quotient is [tex](3^{3} +2x+5)[/tex].
