Can someone help me with this math homework please!
Andreyy89

Answer:

(B) 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:

You've probably seen this function notation format before, most likely f(x). Other common ones are g(x) and p(x). The f, g, and p are just function names, like the h in this question.

The t in the parentheses is the input, because it's the same as the t in 210 - 15t.

Together, h(t) is the output, which is the exact same as y if you used the formula y = mx + b.

Hope it helps (●'◡'●)

Give the numerical coefficient of the term -19x
Elenna [48]

Answer: The answer is -19.

Step-by-step explanation: We are given to write the numerical coefficient of -9x.

The given expression is a monomial with unknown variable 'x'.

We know that a numerical coefficient of a monomial is a constant multiplied to the variable(s). For example, in the term -5xy, the unknown variables are 'x' and 'y' and the numerical coefficient is -5.

Therefore, in -9x, the unknown variable is 'x' and the numerical coefficient is -9.

Thus, the answer is -9.
