Which of the following shows the correct factorization of x3 - 5x2 - 14x?A. x(x + 7)(x + 2)

B. x(x - 7)(x - 2)

C. x(x + 7)(x - 2)

D. x(x - 7)(x + 2)

Answers

Answer 1

Answer: So, just a note of formatting, to indicate something is an exponent of something else, use the carat (^) sign
for instance
x^3 means x cubed. x3 means 3x.
Anyways, though, let's factor.
You can factor out an x from each variable.
x(x^2-5x-14)
Now, to factor this, think of what will add to -5, and multiply to -14.
-7 and 2 work.
So, this factors out to
x(x-7)(x+2)
Choice D is the correct factorization.

Since slope is calculated using the formula m = StartFraction v 2 minus v 1 Over x 2 minus x 1 EndFraction, the slope of both lines is equivalent to ________. It is given that the lines are parallel, and we calculated that the slopes are the same. Therefore, parallel lines have the same slopes.

Answers

Answer: z-v/x-w

Step-by-step explanation: just did the test with this question and it’s right :)

Final answer:

Parallel lines have the same slopes.

Explanation:

The subject of this question is Mathematics as it involves calculating slopes using a formula.

Slope is calculated using the formula m = (v2 - v1) / (x2 - x1). When two lines are parallel, their slopes are equivalent, meaning that they have the same slope. This is because parallel lines have the same steepness or inclination.

For example, if Line A has a slope of 2 and Line B is parallel to Line A, then Line B will also have a slope of 2.

What is the inverse of the function f(x) = 2x – 10? A. h(x) = 2x - 5B. h(x) = 2x + 5 C. h(x) = 1/2x - 5 D. h(x) = 1/2x - 10

Answers

Answer:

f^-1(x)=1/2x+5

Step-by-step explanation:

y=2x-10

inteechange 'y' with 'x'

x=2y-10

make 'y' the subject

2y=x+10

divide by 2both sides

y=(x+10)÷2

y=1/2x+5

f^-1(x)=1/2x+5

1/8 the sum of 23 and 17

Answers

The correct answer is: $(1)/(8) (23 + 17)$ = 5

Explanation:

1/8 the sum of 23 and 17 can mathematically be written as follows:

$(1)/(8) (23 + 17)$

As the sum of 23 and 17 is written as (23+17), and then multiply it with (1/8).

Now evaluate:

$(1)/(8) (23 + 17)$

$(1)/(8) (40)$

= 5

Hence the correct answer is 5

Further explanation

The Problem:

$(1)/(8)$ the sum of 23 and 17
Write an expression to match and then evaluate.

The Process:

Step-1: Determine the sum of 23 and 17

$\boxed{ \ 23 + 17 = 40 \ }$

Step-2: Calculate $(1)/(6)$ the sum of 16 and 20

$(1)/(8)$ of the sum of 23 and 17 means $(1)/(8)$ multiply the result of adding 23 and 17.

$\boxed{ \ = (1)/(8) * 40 \ }$

We can cross out 8 and 40 because they can be completely divided, but this time we continue the multiplication process.

$\boxed{ \ = (40)/(8) \ or \ 40 / 8 \ }$

$\boxed{\boxed{ \ 5 \ }}$

Thus the result is 5.

Quick Steps:

$\boxed{ \ = (1)/(8) * (23 + 17) \ }$

$\boxed{ \ = (1)/(8) * 40 \ }$

$\boxed{ \ = (40)/(8) \ or \ 40 / 8 \ }$

$\boxed{\boxed{ \ 5 \ }}$
