mojhsa [17]

Answer:

5(x + 1) + 6(x + 2) = 7(x + 3) \\ 5x + 5 + 6x + 12  = 7x + 21 \\ 11x - 7x = 21 - 17 \\ 4x = 4 \\ x =  \frac{4}{4}  \\ x = 1

Which answer represents the range of the logarithmic function given below?
Zepler [3.9K]

Answer:

Option D is correct .i.e., All Real Number

Step-by-step explanation:

Given Logarithmic Function, F(x)=log\,0.5^x

First we simply the function,

F(x)=log\,0.5^x

F(x) = x × log(0.5)

F(x) = -0.30103x  (by putting value of log(0.5) )

Its clear range of F(x) completely depends on value of x .i.e, Domain of Function

Domain of log function is real Numbers

⇒ Ranges is also the Real Numbers

Therefore, Option D is correct .i.e., All Real Number

When negative five is subtracted from a number the result is 10 find the number
levacccp [35]

Answer: second option.

Step-by-step explanation:

Let be "x" the unknown number.

According to the information provided in the exercise, 10 is the result of the subtraction of "x" and -5.

Based on this, you can write the following equation:

x-(-5)=10

To find the value of "x" you must remember the multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-

Then:

x-(-5)=10\\\\x+5=10

Finally, subtracting 5 from both sides of the equation, you get:

x+5-(5)=10-(5)\\\\x=5

Please help I an desperate
kherson [118]

Answer:

A

Step-by-step explanation:

Draw an angle of 15° like this (∠) on a piece of paper, label this angle J, extend the base of the triangle and label the hypotenous 11cm (JK). Do you get the solution now? If no, here is an explanation.

This problem can be explained with sin law,

[Assume KL = 4cm]

(sin15)/4 = (sinL)/11

L = 45.4° or 135° (3 sig. fig.)

Since we got 2 possible case for the angle L, there are two possible set of triangles. Hope this will help you understand more about the problem, comment below if you still have any questions.
