What is the approximate distance between the points (-3, -4) and (-8, 1) on a coordinate grid

motikmotik

Answer:

$D= 7.071$

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

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

Where

$(x_1,y_1) = (-3,-4))$

$(x_2,y_2) = (-8,1)$

Replacing these values in the distance formula

$D =\sqrt{(-8-(-3))^2+(1-(-4))^2}$

$D =\sqrt{(-8+3)^2+(1+4)^2}$

$D =\sqrt{(-5)^2+(5)^2}$

$D =\sqrt{25+25}$

$D =\sqrt{50}$

$D= 7.071$

Hence the Distance is 7.071 units

sandy is upgrading her internet service fast charges $60 for installation and $50.45 per month quick internet has free installat

seraphim [82]

Answer:
60+50.45x=57.95x

Cost of Fast Internet:
$60 for installation and $50.45 per month for months =

Cost of Quick Internet:
Free installation and $57.95 per month for months =

We want to know in how many months BOTH COSTS WOULD BE SAME. So we EQUATE the expressions for both. We have:

This equation can be solved for x to find the number of months for which the internet service would cost the same.
