1) linear: this equation just gives us a straight line with no curves
2) linear: this equation gives us a horizontal line
3) non linear: the -2x^2 makes the equation a parabola, so the graph is not a straight line. It looks like an upside down u. Therefore because this equation is a parabola, it is not a linear equation

A partir de la definición de razón y la teoría de semejanza entre triángulos, la razón del área del triángulo AMN y el área del cuadrilátero BMNC es equivalente a 1/3.

<h3>¿Cómo determinar la medida de un lado de un triángulo desconocido?</h3>

En este problema tenemos un sistema formado por dos triángulos <em>similares</em>, la semejanza entre los dos triángulos se debe a la colinealidad entre los segmentos de línea AP' (triángulo <em>pequeño</em>) y AP'' (triángulo <em>grande</em>), así como de los lados AM y AB, así como los lados AN y AC, así como los <em>mismos</em> ángulos en la <em>misma</em> distribución. (Semejanza Lado - Ángulo - Lado)

En consecuencia, obtenemos las siguientes proporciones:

AP'/AP'' = MN/BC = 1/2     (1)

Finalmente, la proporción entre el triángulo AMN y el cuadrilátero BMNC es:

\frac{AMN}{ABC - AMN} = \frac{\frac{1}{2}\cdot a \cdot \left(\frac{1}{2}\cdot h \right)}{\frac{1}{2}\cdot (2\cdot a) \cdot  h - \frac{1}{2}\cdot a \cdot \left(\frac{1}{2}\cdot h \right)} = \frac{\frac{1}{4}\cdot a\cdot h }{a\cdot h - \frac{1}{4}\cdot a \cdot h }

\frac{AMN}{ABC - AMN} = \frac{\frac{1}{4} }{\frac{3}{4} } = \frac{1}{3}

A partir de la definición de razón y la teoría de semejanza entre triángulos, la razón del área del triángulo AMN y el área del cuadrilátero BMNC es equivalente a 1/3.

7x/5+5/2=x/10+1/5<br> SHOW WORK!!! <br> PLEASE HELP!!!!<br> WILL MARK BRAINLIEST
Anettt [7]

Answer:

- 23/13

Step-by-step explanation:

1. Subtract 5/2 from both sides of the equation.

2. Simplify

7/5 = /10 − 23/10

3. Multiply all terms by the same value to eliminate fraction denominators.

7/5 = /10 − 23/10          2 ⋅ 5 ⋅ 7/5 = 2 ⋅ 5( /10 − 23/10)

4. Simplify

14 = − 23

5. Subtract from both sides of the equation.

14 = − 23                              14 − = − 23 −

6. Simplify

13 = − 23

7. Divide both sides of the equation by the same term.

13<em>x </em>= −23                          13x/13 = -23/13

8. Simplify

= −23/13

If (44)x = 432, what is the value of x?<br><br> 4<br> 7<br> 8<br> 28
postnew [5]

44 x 4 = 176

44 x 7 =308

44 x 8 = 352

44 x 28 =1232


 none of those will =432

 are you sure you have the right numbers?


(44)x=432

x=432/44 = 9.8181
