<em><u>2y </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em><em><u> </u></em></h3>
Given -
5x - y = (-1)
-5x + 3y = 25
To find - Summation of this
5x - y = (-1)
+ (-5x) + 3y = 25
adding both the equation we get,
5x +(-5x) - y + 3y = (-1) + 25
0 + 2y = 24
2y = 24.
Answer:
2y = 24
Step-by-step explanation:
5x – y = -1
<u>+ - 5x + 3y = 25</u>
2y = 24
Hence, A. 2y = 24 is the right answer.

Answer:
x = 3,7
Step-by-step explanation:
x² - 10x + 21 = 0
x² - 7x - 3x + 21 = 0
x(x - 7) - 3(x - 7) = 0
(x - 3)(x - 7) = 0
x = 3, 7
Means the graph cuts the x-axis at 3 and 7
5 log 3 + log 4 can be written as:
A. 136 sq. units is the answer. This answer was achieved by simply plugging the numbers into the area formula for rectangles. 8 x 17 = 136
32 is the constant because it doesn’t have a letter
