Answer:
-12
Step-by-step explanation:
2 (2x-3y)-5xy
4x-6y-5xy
4(-2)-6(-1)-5*-2*-1
-8+6-10
-12
The angles of a quadrilateral sum to 360 degrees. A pentagon's exterior angles are 108 degrees. A hexagon's exterior angles are 60 degrees. So, <BAL AND <KLA are 60+108 or 168. 168 + 168 = 336. 360-336 = 24. If you write m<ABK as x, you can write the sum of <ABK and <LKB as 2x. If 2x=24, x=12. So, m<ABK is 12 degrees.
The variable X is equal to 16

Answer:
7/1
Step-by-step explanation:
Assuming the numbers given are points (5, 35) & (6, 42).
Remember to use the point-slope formula: (y₂ - y₁)/(x₂ - x₁) = slope
First, set the equation:
Note that this time: (5, 35) = (x₁ , y₁)
(6, 42) =(x₂ , y₂)
Set the equation: (y₂ - y₁)/(x₂ - x₁)
(42 - 35)/(6 - 5)
Simplify: (7)/(1)
7/1 = 7
slope form is 7/1
