Answer:
Natural numbers
Step-by-step explanation:
Rational numbers are numbers which can be expressed in the form a/b ; such that b ≠ 0 ; hence, rational numbers can be certain non-recurring decimal values.
Integer values are numbers which can be written without any fractional component. While natural numbers are characterized as being whole and non-negative
To represent population values, number of people or species cannot be fractional and cannot be negative, hence natural numbers is the best option.
Y = 3x - 4 . . . (1)
9x - 3y = 14 . .(2)
Putting (1) into (2) gives
9x - 3(3x - 4) = 14
9x - 9x + 12 = 14
12 = 14
Therefore, there is no solution.
Answer:
The answer is s=-1 or s=-12
Step-by-step explanation:
First Step: Factor left side of equation.
(s+1)(s+12)=0
Second Step: Set factors equal to 0.
s+1=0 or s+12=0
So, the answer is either -1 or -12
Answer:
Right Triangle
Step-by-step explanation:
An angle created by two perpendicular lines is a right angle, and a triangle with a right angle is a right triangle.
Answer:
4x = -4
Step-by-step explanation:
since "which of these" are not shown, I'm going offroad here
the next obvious step would be to subtract 8 from both sides
4x = -4
