Answer:

zero

Step-by-step explanation:

Dividing the second equation by -3, it becomes ...

x -3y = 7/3

Compared to the first equation, ...

x -3y = 5

we see that it is <em>inconsistent</em>. No values of the variables can satisfy both equations. There are no solutions.

Nice work ! With this deceptively brief question, you score a twofer.

We don't know which graph, and we likewise don't know which behavior.

Otherwise, we're all over it.

Question 1 of 5

kifflom [539]

Answer:

Step-by-step explanation:

Area of rectangle = length * width

= 6 * 4.8

= 28.8 square ft

$Area\ of \ triangle = \dfrac{1}{2}bh$

$= \dfrac{1}{2}*6*3.5\\\\=3*3.5\\\\\\= 10.5 \ ft^{2}$

Area of the figure = area of rectangle + area of triangle

= 28.8 + 10.5

= 39.3 ft²
