We have to use the functions:
h ( x ) = 2 x + 5 and t ( x ) = 7 x - 6
Part A:
( h + t ) ( x ) = ( 2 x + 5 )  + ( 7 x - 6 ) = 9 x - 1
Part B :
( h · t ) ( x ) = ( 2 x + 5 ) · ( 7 x - 6 ) = 14 x² - 12 x + 35 x - 30 =
= 14 x² + 23 x - 30
Part C :
h [ t ( x ) ] = h ( 7 x - 6 ) = 2 · ( 7 x - 6 ) + 5 = 14 x - 12 + 5 =
= 14 x - 7

Find the domain of where f(x) = x + 10 and g(x)=x².
ASHA 777 [7]

The domain of the function f(x)=x+10 is (-∞, ∞) and for the function g(x)=x² is (-∞, ∞).

<h3>What is meant by domain?</h3>

If a formula specifies a real function f, it may not be defined for some values of the variable. The natural domain or domain of definition of f is the set of real numbers on which the formula can be evaluated to a real number in this case. A partial function is often referred to just as a function, and its natural domain is referred to simply as its domain.

Given,  f(x) = x + 10

g(x)=x²

The domain for the function f(x)=x + 10

So, the domain of f(x)=x+10 is (-∞, ∞)

The domain for the function g(x)=x²

The expression's domain is only real numbers, with the exception of places where it is undefined. Because there is no real number in this scenario, the expression is undefined.

So, the domain of the function g(x)=x² is (-∞, ∞)

100 POINTS! MUST EXPLAIN ANSWER!
Irina-Kira [14]

Answer:

Answer: A and B.

Step-by-step explanation:

Supplementary angles are a pair of angles that add 180 degrees.

A. Show two angles that form a 180 degree angle, so they are supplementary.

B. This angles add 180 degrees, so they are supplementary.

C. The two angles add 90 degrees, so they are complementary, not supplementary.

D. This angles add 90 degrees, so they are complementary, not supplementary.
