Ax + By = C. -A/B is the slope and C is intercept
Answer:
I think 4
Step-by-step explanation:
If FG = 2 and EF looks very similar, EG would be 4 and EH=8, 8-4=4
Answer:
25000 in all
Step-by-step explanation:
Hope this helps btw you have to multiply.
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.
The rule is:
(a^b)^c=a^(b*c)
In this case:
(9^3)^4=9^(3*4)=9^12
and if you wanted it more simplified you could say:
9^12=(3^2)^12=3^(2*12)=3^24
