(-4,-6) and (3,-7) find the distance between each pair of points

Vlad [161]

Answer:

$5\sqrt{2}$

Step-by-step explanation:

distance between two points:

$d = \sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2}}$

we have:

(-4, -6), (3, -7)

$x_{1} = -4$

$y_{1} =-6$

$x_{2} = 3$

$y_{2} =-7$

so we have:

$d =\sqrt{(3-(-4))^{2}+ (-7-(-6))^{2}}\\\\d =\sqrt{(7)^{2}+ (-1)^{2}}\\\\d = \sqrt{49+ 1}\\\\d=\sqrt{50}\\\\d=5\sqrt{2}$

What is X over 8 =9

Liula [17]

Answer: x = 72

Step-by-step explanation: Although the problem is saying "X over 8", this really signifies that the x is being divided by 8 which is what a fraction is, numerator divided by a denominator.

Let's first undo what has been done. Since our variable is being divided by 8, we'll undo that by multiplying by 8 on both sides. It's important to remember, whatever you do on one side,

you must do to the other side.

If you look now, the 8 in the numerator and the 8 in the denominator will divide out and it will leave us with our variable which is x. Working on the other side now, 9 x 8 is equal to 72 so x = 72 is our answer.

We can check our answer by plugging a 72 back into the original equation. So we have 72/8 = 9 which is a true statement

so our answer is correct.
