Answer:
Solution,
x+12+8x-2=180° (Linear pair)
or, 9x+10=180°
or, x+10=180/9
or, x=20-10
x=10
The length of MT
=8x-2
=8×10-2
=80-2
=78
hope it helps you
Answer:
Step-by-step explanation:
the number is 1300 if we have 40% from it will give us 520
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:
8 + 4
Step-by-step explanation:
It is a fact family.
You can arrange it any way as long as you keep the 2 as the very first number
