When trying to determine the distance between two points, one would use the distance formula.

The distance formula is attached above and all you need to do is plug in the points in order to get the distance.

For example, if you were to plug them in, you would get:

√(0+4)^2 + (0+2)^2

marin [14]

Answer:

4 seconds to reach 200 feet

Step-by-step explanation:

You can use Desmos (graphing calculator) then plug in the equation and you will find the x-values are 7.188 and 0- the origin.

Divide 7.188 by 2 (this is also solving for the midpoint/axis of symmetry) and you get 3.594

Round 3.594 to the nearest second which would be 4 seconds.

Hope that helps and have a great day!

What is the value of x in the equation -6x= 5x + 222<br> -22<br> -2<br> 2

Leokris [45]

Answer:

$x=-20\frac{2}{11}$

Step-by-step explanation:

- 6x = 5x + 222

- 222 = 5x + 6x

11x = - 222

x = - 222 : 11

x = - 222/11

$x=-20\frac{2}{11}$

Three streets intersect to form a right triangle as shown below. The parts of streets that make up the legs of this triangle are

Burka [1]

Answer:

70 yd.

Step-by-step explanation:

The three streets at the intersection form a right triangle.

For a right triangle, the length of the longest side (called hypothenuse) is given by Pythagorean's theorem:

$h=\sqrt{x^2+y^2}$

where

x is the length of the 1st side

y is the length of the 2nd side

h is the length of the hypothenuse

Here we want to find the hypothenuse.

We have:

x = 42 yd (length of the 1st side)

y = 56 yd (length of the 2nd side)

Substituting, we find h:

$h=\sqrt{42^2+56^2}=70 yd$

4-5 (2-1)=how to sove it

DerKrebs [107]

$4 - 5(2 - 1) = \: ?$

PEMDAS states to do what's in the parenthesis first...

$4 - 5(1)$

PEMDAS states to multiply 5 by 1 next...

$4 - 5$

PEMDAS states to subtract 4 by 5 next...

$= - 1$
