answer: 3.8857

explanation:

Simplifying

-5k + 2.9 = -12k + 30.1

Reorder the terms:

2.9 + -5k = -12k + 30.1

Reorder the terms:

2.9 + -5k = 30.1 + -12k

Solving

2.9 + -5k = 30.1 + -12k

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '12k' to each side of the equation.

2.9 + -5k + 12k = 30.1 + -12k + 12k

Combine like terms: -5k + 12k = 7k

2.9 + 7k = 30.1 + -12k + 12k

Combine like terms: -12k + 12k = 0

2.9 + 7k = 30.1 + 0

2.9 + 7k = 30.1

Add '-2.9' to each side of the equation.

2.9 + -2.9 + 7k = 30.1 + -2.9

Combine like terms: 2.9 + -2.9 = 0.0

0.0 + 7k = 30.1 + -2.9

7k = 30.1 + -2.9

Combine like terms: 30.1 + -2.9 = 27.2

7k = 27.2

Divide each side by '7'.

k = 3.885714286

Simplifying

k = 3.885714286

hope this helped;))))

Domain is the numbers you can use
range is the result of inputing the domain

an interesting fact is that the inverse of a function switches the domain and range

basically
the domain of f(x) becomes the range of f^-1(x)
the range of f(x) becomes the domain of f^-1(x)
so just find the domain and range of f(x)

$f(x)=3x- \frac{1}{2}$
there are no restrictions
all real numbers can be used
all real numbers can result

so the answer is domain and range for both is all real numbers

Alex is practicing his dives at a pool. He dies from the diving board that is 15 feet above the surface of water. His dive takes

PIT_PIT [208]

Answer:

Alex is wrong in calculating his dive distance Actual Dive distance is 30 feet.

Step-by-step explanation:

Given:

Distance from where he dive from = 15 feet

Distance he reached after dive = 15 feet

Also Given:

Alex says that the two distances are opposites,

Also Total distance of dive according to Alex = 15 +-15 =0 feet

Solution:

We know that the diving board is 15 feet above the water level, but here it is important to know that even he is above the surface of the water he is diving in the water and then he reached 15 deep in the water.

From above scenario we can say that the two distances are in the same direction.

Total Distance of dive will be = 15 +15 =30 feet.

Hence We can say that Alex is wrong in calculating his dive distance Actual Dive distance is 30 feet.

P(x)=(x-2)(x-4)(x-5)

Cerrena [4.2K]

The constants of a polynomial is the term that has no variable attached to it.

<h3>The constant term</h3>

To determine the constant, we simply multiply the constant term in each factor of the polynomial.

So, we have:
