The numeric value of the expression -a² - 2bc - |c| for a = -3, b = -5 and c = 2 is of 9.

<h3>How to find the numeric value of an expression?</h3>

The numeric value of an expression is found replacing each letter by it's attributed value.

In this problem, the expression is:

-a² - 2bc - |c|

The attributed values are:

a = -3, b = -5 and c = 2

Hence the numeric value will be given by:

-a² - 2bc - |c| = -(-3)² - 2(-5)(2) - |2| = -(9) + 20 - 2 = -9 + 18 = 9.

Precalc help needed, find g ° f!
Nezavi [6.7K]

Answer:

g o f = -[f(x)]² + 3 = -(|x|)² + 3 = -x² + 3 = g(x)

Step-by-step explanation:

g o f = g [ f(x) ]

This means replace the x of g(x) with f(x):

g o f = -[f(x)]² + 3 = -(|x|)² + 3

As x² ≥ 0 for any value of x (whether it be positive or negative), then -(|x|)² + 3 = -x² + 3 = g(x)

So g o f = g(x)

Andrej [43]

Answer:

1)

2( \frac{3}{4} )= 5 \\  \frac{3}{2}  = 5 \\ 3 = 5 \times 2 \\ 3 = 10

2)

3( 4 \times 2) = 1 \\ 3(8) = 1 \\ 24 = 1

3)

\frac{1}{4}  +  \frac{4}{3}  \\  \frac{1}{1}  +  \frac{1}{3}  \\ 1 \times 3 + 1 \times 1 \\ 3 + 1 \\ 4
