Answer:

(1, 9 )

Step-by-step explanation:

Given the 2 equations

- x + y = 8 → (1)

y + 3x = 12 → (2)

Subtracting (2) from (1) term by term will eliminate the term in y, that is

(- x - 3x) + (y - y) = (8 - 12)

- 4x = - 4 ( divide both sides by - 4 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting in (2)

y + 3(1) = 12

y + 3 = 12 ( subtract 3 from both sides )

y = 9

Solution is (1, 9 )

Find the area of quadrilateral ABCD in each case.<br> HElp PLEase ASAP
ahrayia [7]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

Let's see...

Step-by-step explanation:

*Note: we can't find the exact area of the shaded figure right off the bat, we have to find the area of a bigger figure and divide it by 2.

<h3>The coordinates of the bigger figure:</h3>

A = (0,0)

B' = (0,4)

C = (5,4)

D' = (5,0)

Note: the little [ ' ] next to the B and D indicate that it is not the same coordinate as B and D, just that those points would be the same as point B and D.

<h3>That being said, what is the area of the bigger figure?</h3>

A =  l * w

A = 4 * 5

A = 20 units²

<h3>Now, divide the Area by 2:</h3>

A = 20 ÷ 2

<em>A = 10 units²</em>

I hope this helps!

What is the answer to this problem?
leonid [27]

Answer:

\frac{7}{9}

Step-by-step explanation:

If you add a number that is negative, you are basically subtracting it.

This means that

\frac{8}{9}+\left(-\frac{1}{9}\right)=\frac{8}{9}-\frac{1}{9}

Since they both have the same denominator, you can easily subtract the fractions: \frac{8-1}{9}=\frac{7}{9}
