Answer:

x=142, y=-360. (142, -360).

Step-by-step explanation:

5x+2y=-10

3x+y=66

----------------

5x+2y=-10

-2(3x+y)=-2*66

-----------------------

5x+2y=-10

-6x-2y=-132

-------------------

-x=-142

x=142

3(142)+y=66

426+y=66

y=66-426

y=-360

Answer:

1- 5x+2y+−2y=−10+−2y

5x=−2y−10

\frac{5}{5}= \frac{-2y-10}{5}

x= \frac{-2}{5}y-2

2-  3x+y+−y=66+−y

3x=−y+66

\frac{3x}{3} = \frac{-y+66}{3}

x=\frac{-1}{3}y+22

Step-by-step explanation:

Fittoniya [83]

Answer:

<u>direction</u>

<u>shape</u>

<u>scatter plots</u>

<u>shape and outliers</u>

Step-by-step explanation:

Correlation is defined as the degree of correspondence between two variables.

When the values increase together, correlation is positive and when one value decreases as the other increases, correlation is negative .

Calculating a correlation can help describe a relation between two quantitative variables' <u>direction</u> and <u>shape</u>. However, it is not sufficient to use a correlation coefficient to describe two variables.  The addition of <u>scatter plots</u> can provide other helpful details such as <u>shape and outliers</u>
