Right answer is:
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.
Step-by-step explanation:
Lets define the terms first
An independent variable is a variable whose values are put in the function. It is the input of a function.
While dependent variable's value depends on the independent variable.
Given function is:
By observing the function, we can see that the function is in terms of t which means that t is the input for the function while h is the name of the function. h(t) which be obtained by putting the values of t is the output.
So,
Right answer is:
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.

Answer: 45°
Step-by-step explanation:
Given that :
∠A=5x−15°---(1)
∠B=2x+21°----(2)
Equating
∠A = ∠B
(5x−15)° = (2x+21)°
5x - 15 = 2x + 21
Collecting like terms
5x - 2x = 21 + 15
3x = 36
x = 12
Substitute x = 12 in either angle A or B since both are congruent
∠A=(5x−15)°
∠A = (5(12) - 15)°
∠A = (60 - 15)°
∠A = 45°
∠A = ∠B = 45°
Answer:
x = - 1 and x = 5
Step-by-step explanation:
Given
(x - 3)² + 2(x - 3) - 8 = 0
Let u = x - 3, then
u² + 2u - 8 = 0 ← solve for u
(u + 4)(u - 2) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 4 = 0 ⇒ u = - 4
u - 2 = 0 ⇒ u = 2
Convert back to x, that is
x - 3 = - 4 ( add 3 to both sides ) ⇒ x = - 1
x - 3 = 2 ( add 3 to both sides ) ⇒ x = 5
3(4x + 6) - 9x
Apply the Distributive Property:
3 (4x) + 3 * 6 - 9x
Multiply by 4 by 3 to get 12:
12x + 3 * 6 -9x
Multiply 3 by 6 to get 18:
12x + 18 - 9x
Subtract 9x from 12x to get 3x:
3x + 18
Your answer is the second option!
