What values of x is log (2x-5) valid

Answers

Answer 1

Answer:

To solve this you must first know how Log works.

When we say log1000 of base 10

Or

log1000=3

What we actually say is for the power 3(value on RHS) of 10(the base of log) we get 1000(the value on which log is performed).

So log2x=−5 (i am assuming base 10 since it is simple algebra) means that

2x=10−5

x=10−5/2

Do this simple calculation and you have it. If anything is unclear/incorrect feel free to comment.

The question is not written properly, so I will give the answer(s) I think would be suitable.

If you were trying to solve this

log2x=−5

⟹x=2−5

⟹x=132

But if you were trying to solve this

log2x=−5

⟹log102x=−5

⟹2x=10−5

⟹x=12×105=1200000

Triangles MNQ and MOP are similar. What is the slope of segment MO?

A. 1/3
B. 1/2
C. 2/3
D. 3/2

Answers

Answer:

D. 3/2

Step-by-step explanation:

The scale factor is 1/2 from OP / NQ = 1/2. Because of that, MQ is equal to half of MP and QP is equal to half of MP. Therefore, QP = MQ = 2. The slope of MO is rise over run which is 6 / 4 or 3 / 2.

¿Cuáles son las longitudes de un terreno rectangular, si se sabe que el ancho es dos veces más pequeño que el largo, y que su área es de 16, 200 m2? cuanto mide el ancho cuanto mide el largo

Answers

Answer:

El largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m

Step-by-step explanation:

Un rectángulo es un cuadrilátero con dos lados de igual longitud y dos lados de igual ancho que contiene cuatro ángulos rectos. Para encontrar el área de un rectángulo, debes multiplicar su longitud por su ancho. Es decir, el área del rectángulo es igual al largo por el ancho.

En este caso, sabes que el ancho es dos veces más pequeño que el largo. Entonces, siendo el largo x, el ancho tendrá un valor de x÷2.

Siendo el área del terreno rectangular 16,200 m², entonces

x*(x÷2)= 16,200 m²

Resolviendo:

x² ÷2= 16,200 m²

x²= 16,200*2 m²

x²= 32,400 m²

x= √32.400 m²

x= 180 m

Entonces, el largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m (180 m÷ 2)

Answers

Answer:

Step-by-step explanation:

In parallelogram opposite angles are equal

6x = 66      {Divide both sides by 6}

x = 66/6

x = 11

20y - 46 = 13y + 10     {Add 46 to both sides}

20y - 46 + 46 = 13y + 10 + 46

             20y   = 13y + 56     {Subtract 13y from both sides}

   20y - 13y    = 13y-13y + 56

              7y    =  56    {Divide both sides by 7}

                y =  56/7

y = 8

Answer: 3

Why?
You need two points to find slope I will use 5,19 and 2,10.
Slope is the difference of Y over the difference of x
19-10/5-2= 9/3 (simplify but divided each by 3)
3/1 so the slope is 3
