Answer:

A. The distance is the same

Step-by-step explanation:

This is like absolute value. No matter the side of 0 that the point is on, it is still the same distance from zero. The direction left or right is different, but it doesn't ask for that. Both 6 and -6 is 6 units away from 0.

A line had a slope of 2/3 and a y intercept at (0,14).What is the x intercept of the line?​
pychu [463]

Answer:

y=2/3x+14

Step-by-step explanation:

The standard form of an equation in slope-intercept form is y=mx+b where m=slope and b=y-intercept.

Given a y-intercept of 14 and a slope of 2/3, we can plug into the variables and get the equation y=2/3x+14

The x-intercept would be when y=0, so plugging in y=0 to the equation gets us:

0=2/3x+14

-14=2/3x

21=x

So the x-intercept is 21

$470 is raised by 30%. What is the value after the increase?
alekssr [168]
<h3>Answer:  $611</h3>

Work Shown:

30% of 470 = 0.30*470 = 141

The value goes up by $141, so the answer would be 470+141 = $611

A slight shortcut would be to say

1.30*470 = 611

This works because 1.30 = 1 + 0.30 = 100% + 30%

Using the Law of Detachment if a polynomial is prime, then it cannot be factored. 5x+13y is prime.
frozen [14]

Answer and Step-by-step explanation: <u>Law</u> <u>of</u> <u>deduction</u> is a mathematical logic that states the following:

1) If p happens, then q happens;

2) p is true;

Then, a there is a third statement that is

3) q is also true.

In this question,

If a polynomial is prime, then it cannot be factored.

Statement p is that 5x + 13y is a polynomial and is prime, i.e., p is true.

Statement q is that "it cannot be factored"

Therefore, 5x + 13y cannot be factored.
