Answer:

The distance between (5,8), and (-1,4) is (6, 12).

Step-by-step explanation:

All you have to do is think of it as a line. -1 is here, to get to positive 5, you must move 6; -4 is there, to get to positive 8, you must move 12.

Answer:

\huge\boxed{\sqrt{180} \ \ \text{or}  \ \ 13.42}

Step-by-step explanation:

In order to find the distance between two points, we can use the distance formula. The distance formula states that the distance between two points is

\sqrt{(x_2 - x_1)^2 + (y_2 - y_1) ^2}

(5,8) is our first coordinate and (-1,-4) is our second. So, we can substitute these values into the equation.

\sqrt{(-1 - 5)^2 + (-4 - 8) ^2}\\\\\sqrt{(-6)^2 + (-12) ^2}\\\\\sqrt{36 + 144}\\\\\sqrt{180} \approx 13.42

| 2 +r | ≥ 3 (lines are absolute value)
Alex777 [14]

Answer:

r ≤ -5 and r ≥ 1

Step-by-step explanation:

The solution has two parts:

1) that derived from | 2 +r | ≥ 3 when (2 + r) is already positive.  Then:

                   2 + r ≥ 3, or r ≥ 1

and

that derived from | 2 +r | ≥ 3 when (2 + r) is negative.  If (2 + r) is negative, then

|(2 + r)| = -(2 + r) = -2 -r, which is ≥ 3.  Therefore, -2 -r ≥ 3, or -r ≥ 5.  To solve this for r, divide both sides by -1 and reverse the direction of the inequality sign:  r ≤ -5

45% of a number is 180. Find the number
KonstantinChe [14]

Answer:

81

Step-by-step explanation:

The term "of" can be translated to multiplication in problems like this.

So it's essentially saying multiply 45% to 180 and give me the result.

45% can be written as 45/100 in fractions (45 percent, where cent means 100 and per means division). 45/100 can be written as 0.45 in decimal form.

Now the problem reads 0.45 X 180. Using a calculator, we can solve this and the result comes out to be 81
