x - 2y = -1
a: 2
If equation one is multiplied by 2 and then the equations are added, the result is _____.
3x = 2 this is the answer
3x = 5
5x = 5</span>
P= 3000 (1.21)^t, t= time in months
1 year = 12 months, and therefore, 1 month = 1/12 years
The equation showing yearly population growth changes to;
P=3000 (1.21)^t/12
The correct answer is equation [1].
I think 11 is yes, if the parent is 40 and the child is 20. (and they had kids when they were young) 12 is yes, if the parent is 30 and the child is 10. 13 is yes, if the parent is 60 and the child is 40. unlikely though, but who cares. 14 is no, the parent would have been really young when they gave birth to the child. like 10.
(0,346)(2,344.8)
slope = (344.8 - 346) / (2 - 0) = -1.2 / 2 = -0.6
y = mx + b
slope(m) = -0.6
(0,346)...x = 0 and y = 346
now we sub and find b, the y int
346 = -0.6(0) + b
346 = b
so ur equation is : y = -0.6x + 346....with x being the number of weeks
after 4 weeks...
y = -0.6(4) + 346
y = - 2.4 + 346
y = 343.6 <==== after 4 weeks
after 9 weeks..
y = -0.6(9) + 346
y = -5.4 + 346
y = 340.6 <=== after 9 weeks
