<h2>Answer:</h2>

1 ---- Complementary angles

2 ---- Vertical angles.

3 ---- Adjacent angles

4 ---- Supplementary angles

<h2>Step-by-step explanation:</h2>

<u>Complementary angles--</u>

Two angles are said to be complementary if the sum of two angles is 90 degree.

<u>Supplementary angles--</u>

Two angles are said to be supplementary if the sum of two angles is 180 degree.

<u>Vertical angles--</u>

It is the pair of angles that are made by two intersecting rays.

Angles with sides that form two pairs of opposite rays .

<u>Adjacent angles--</u>

The angles which have a common vertex and a common side but no common interior points.

Answer:

x + x+12 + 3(x+12) = 123

x = 15

Step-by-step explanation:

Jamil : x

Kiera : x+12

Luther : 3 ( x+12)

x + x+12 + 3(x+12) = 123

Distribute

x + x+12 + 3x+36 = 123

Combine like terms

5x+ 48 = 123

Subtract 48 from each side

5x+48-48 = 123-48

5x =75

Divide by 5

5x/5 = 75/5

x = 15

Solve for r -4(r+6)= -49

tatiyna

Answer: r= 25/3

Step-by-step explanation:

r-4(r+6)=-49 distribute the 4

r-4r-24=-49 combine like terms

-3r-24=-49 add 24 to both sides

-3r=-25 divide by -3

r= 25/3 answer

How do I get the answer to this math problem n + 7 < -3 what is the formula for the math problem

laiz [17]

If I understand the question, you have to get n alone. in this case, you have to subtract 7 from both sides, resulting in n (is less than) -10

Unit activity: exponential and logarithmic functions

nirvana33 [79]

We will conclude that:

The domain of the exponential function is equal to the range of the logarithmic function.
The domain of the logarithmic function is equal to the range of the exponential function.

<h3>Comparing the domains and ranges.</h3>

Let's study the two functions.

The exponential function is given by:

f(x) = A*e^x

You can input any value of x in that function, so the domain is the set of all real numbers. And the value of x can't change the sign of the function, so, for example, if A is positive, the range will be:

y > 0.

For the logarithmic function we have:

g(x) = A*ln(x).

As you may know, only positive values can be used as arguments for the logarithmic function, while we know that:

$\lim_{x \to \infty} ln(x) = \infty \\\\ \lim_{x \to0} ln(x) = -\infty$

So the range of the logarithmic function is the set of all real numbers.

<h3>So what we can conclude?</h3>

The domain of the exponential function is equal to the range of the logarithmic function.
The domain of the logarithmic function is equal to the range of the exponential function.
