Answer:
"The sum of two rational numbers is rational."
By definition, a rational number can be expressed as a fraction with integer values in the numerator and denominator (denominator not zero). So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
If I remember correctly it should be B because every input has to have 1 output. I apologize if it’s wrong ( I haven’t had those problems since 8th grade I’m currently in 10th)
The answer would be 70.. All you do is divide 0.14 into 9.8 to et you anwer of 9.8 into 0.14 soory not the best at explaining...
X^2 - 2x - 8
2 numbers that multiplied give -8
2 numbers that added give -2
2 x -4 = -8
2 + -4 = -2
(x + 2) (x -4 )
roots equal = -2, 4
x^2 - 2x -8
a. b. c because b is -2 in the equation you don't plug b as a negative
in the axis of symmetry
axis of symmetry = -b divide by 2a
2 divide by 2(1) =1
Vertex= (1, -9)
