What is 3lna+lnb−lnc written as a single logarithm?

-(x+3) = 2x-6 what is x

Makovka662 [10]

Answer:

x=1

Step-by-step explanation:

So, first you make sure to multiply the parenthesis by the negative so then it would be,

-x-3=2x-6

Then you add the -3 from the right to the other side

so, -x=2x-3

Then you want all the X variables to one side so you subtract the 2x to both sides.

so, -3x=-3

divide both by -3

x=1

100 POINS, Help

Answer: Translate triangle ABC so that point B lies on point D to confirm ∠B ≅ ∠D.

Step-by-step explanation: Since we already know that angle A is congruent to itself by the reflexive property, all we need is another pair of corresponding angles to be congruent according to the AA (angle-angle) similarity postulate. This postulate states that; If two corresponding angles of two or more triangles are congruent, the triangles are similar. So when we translate triangle ABC so that point ∠B lies on ∠D, we prove that these two angles are congruent.

I also got it right on the test. So... yeah.

hope this helps dood.

Determine which of the following terms is a function: a. (1,2) (2,4) (3,5) c. (1,2) (2,4) (2,6) b. (1,2) (2,3) (1,5) d. (1,2) (3

Komok [63]

In a function, X does not repeat.
Your answer is A.

a (1,2) (2,4) (3,5)
there are different x values for
each point, so this IS A FUNCTION.

b. (1,2) (2,3) (1,5)
there are two values of x being 1,
so this is NOT A FUNCTION.

c. (1,2) (2,4) (2,6)
there are two values of x being 2
so this is NOT A FUNCTION.

d. (1,2) (3,5) (3,7)there are two values of x being 3,
so this is NOT A FUNCTION.

hope this helps and have a great day!

Given: AB ≅ CD and AD ≅ BC

enot [183]

Answer:

SSS congruency theorem ⇒ 3rd answer

Step-by-step explanation:

* Lets revise the cases of congruent

- SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ

- SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and

including angle in the 2nd Δ

- ASA ⇒ 2 angles and the side whose joining them in the 1st Δ

≅ 2 angles and the side whose joining them in the 2nd Δ

- AAS ⇒ 2 angles and one side in the first triangle ≅ 2 angles

and one side in the 2ndΔ

- HL ⇒ hypotenuse leg of the first right angle triangle ≅ hypotenuse

leg of the 2nd right angle Δ

* Lets complete the missing

- Given: AB ≅ CD and AD ≅ BC

- Prove: ABCD is a parallelogram

* Statements Reasons

1. AB ≅ CD ; AD ≅ BC given

2. AC ≅ AC reflexive property

3. △ ADC ≅ △ CBA SSS congruency theorem

- The three sides in Δ ADC equal the three sides in ΔCBA,

then the two triangles are congruent by SSS theorem

∴ The missing reason in step 3 is SSS congruency theorem
