Answer:
u^2 +7u -8=0 where u = 3x+2
Step-by-step explanation:
(3x+2)^2 + 7(3x+2) - 8=0
Let 3x+2 = u
u^2 +7u -8=0
Step-by-step explanation:
y = 2/5 x - 9/5
when x = -1,
the value of y = 2/5(-1) - 9/5
= -2/5 - 9/5 = -11/5
when x = 0
=> y = 2/5(0) -9/5
= 0-9/5 = -9/5
when x=1
=> y = 2/5(1) - 9/5
= 2/5 - 9/5 = 7/5
Current worlds population is 7.6 billion (7,600,000,000), so Japan’s population is equal to 1.67 % of the world’s population.
Step-by-step explanation:
We need to factorise 3x
2
−12xy
Here we can take 3x common.
Thus we have 3x
2
−12xy=3x(x−4y)
Hence, factors are 3x,(x−4y).
