Answer:

-4

Step-by-step explanation:

Notice that the only way to multiply 2 numbers from each of the polynomials and get an x term is to multiply a constant and an x term.

The only ways to do that is to multiply -6x by 3 and 7x by 2.

After you're done multiplying, just combine the 2 like terms:

-18x+14x

=-4x

Therefore, the coefficient of the x term is -4.

Evaluate the function rule for the given value. y=15*3^x for x = -3
DENIUS [597]

Answer: y=\frac{5}{9}

Step-by-step explanation:

It is important to remember that an Exponential function has the following form:

f(x) =a* b^x

Where  “b”  is b > 0 and b \neq 1 , "a" is a coefficient, "x" is the Independent variable and f(x) is the Dependent variable.

In this case, you have the following Exponential Function given in the exercise:

y=15*3^x

If the value of Dependent variable is -3, then:

x=-3

So, you must substitute that value of "x" into the function:

y=15*3^{(-3)}

And now you must evaluate:

1. According the Negative exponent rule:

a^{-n}=\frac{1}{a^n}

Then:

y=\frac{15}{3^{3}}

2. Simplifying, you get:

y=\frac{15}{27}\\\\y=\frac{5}{9}

In order to be invited to tutoring or extension activities a students performance 20 point higher or lower than average for the
GalinKa [24]

Answer:


Step-by-step explanation:For the student to be considered for the tutoring or extension activities, his/her score must be 20 points lower or higher than the average.


The average is given as 105, that means:


Minimum score to be considered = 105 - 20 = 85


Maximum score to be considered = 105 + 20 = 125


If p represents the performance of a student, then this inequality will be represented as follows:


                    85 ≤ p ≤125
