I also speak English but that's no fun
Take the area of the rectangle without the indent, then subtract the area of the indent:
(9)(13) - (5)(8)
Area = 77
Given that the horizontal line that passes through the point (-5,9)
We need to determine the equation of the horizontal line.
<u>Horizontal line:</u>
The formula to determine the equation of the horizontal line is given by
where b is the value of y
Thus, from the point (-5,9), the value of b is
Thus, the formula to determine the equation of the horizontal line is given by
Hence, the equation of the horizontal line is
Thus, Option B is the correct answer.
Answer:
(30, 25)
Step-by-step explanation:
Substitute (2/3)x + 5 for y in the second equation:
7x - 3([2/3]x + 5) = 15
Then:
7x - 2x - 15 = 15, or:
5x = 30. Thus, x = 30, and from the first equation we get:
y = (2/3)(30) + 5 = 20 + 5 = 25
The solution is (30, 25)
