Answer:
Step-by-step explanation:
-9x - 15y = -6
9x + 11y = 14
-4y = 8
y = -2
3x - 10 = 2
3x = 12
x = 4
(4, -2)
Answer:
The answer is 15 cm
Step-by-step explanation:
as one square is 1 cm and there are 15 squares used for this shape then it is 15 cm
I believe this is called a wage
Answer:
B
Step-by-step explanation:
equation of a line is in the form of y=mx+b where m is the slope and b is the y intercept
slope: -1-2/0-4 = 3/4
y intercept is when x is 0, so y intercept is -1
therefore the equation of this line is y=3/4x-1
Answer:
The correct answer is option D. 69°
Step-by-step explanation:
Points to remember
1). The sum of angles in a linear pair is 180°
2). In a triangle sum of two angles are equal to the exterior angle of third angle
From the figure we can see a triangle in which two exterior angles area given.
<u>To find the value of n</u>
from figure we get,
n = (interior angle of 131° + interior angle of 160°)
interior angle of 131° = 180 - 131 = 49°
interior angle of 160° = 180 - 160 = 20°
n = 49° + 20° = 69°
Therefore the correct answer is option D. 69°
