Answer:

(x,y)=(-8,-1)

Step-by-step explanation:

(2) rearrange

x=-2+6y

-4(-2+6y)+5y=27

8-24y+5y=27

8-19y=27

-19y=19

y=-1

x=-2+6(-1)

x=-2-6

x=-8

Hope this helps :)

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:

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

To determine whether a cause-effect relationship exists between two variables, a researcher must use.

Thepotemich [5.8K]

To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.

<h3>What is cause-effect relationship?</h3>

A cause-and-effect relationship is one which satisfies some conditions like:

two events occur at the same time and in the same place
one event immediately precedes the other

Therefore, To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.
