Answer:
should be 13
Step-by-step explanation: 6.5 x 2
Step-by-step explanation:
xy + 10 = 0. => y = -10/x.
2x + 3y = 7. => 3y = -2x + 7, y = -2/3 x + 7/3.
When -10/x = -2/3 x + 7/3,
-10 = -2/3 x² + 7/3 x, 2/3 x² - 7/3 x - 10 = 0.
=> 2x² - 7x - 30 = 0
=> (2x + 5)(x - 6) = 0
=> x = -2.5 or x = 6.
dy/dx = d/dx [-10/x] = 10/x².
When x = -2.5, dy/dx = 10 / (-2.5)² = 1.6.
When x = 6, dy/dx = 10 / (6)² = 5/18.
Hence the gradients at the points are 1.6 and 5/18.

Answer:
100
Step-by-step explanation:
we first find the area of the rectangle:
8*10=80
now we find the area of the triangle:
(6*8)/2=24
Now we add the area of the triangle and the rectangle up:
24+80=104
Now we round that up to the nearest ten:
100
Answer:
∠HGJ and ∠KJL
Step-by-step explanation:
Corresponding angles are on the same side of the transversal where it cuts the two parallel lines, they have the same measure.
