Answer:
a. 6(7) + 2(3)^2 = 60
b. (5(-18)/3)-2 = -32
c. (6(10))^2 - 10/5 = 3598
d. (1-3)(1+2) = -6
Step-by-step explanation:
Im not sure this question is complete but the answer should be <u><em>152.4</em></u>
Answer:
4 teachers for 28 students
Step-by-step explanation:
28/7 = 4
The rational root (or zero) theorem says a polynomial's rational zeros must have factors of the constant in the numerator and those of the leading coefficient in the denominator.
Here the leading coefficient is 1 and the constant is 5, so our only possibilities for rational roots are 1, -1, 5, -5
We try them each in term
1-3+1+5=6 nope
-1 -3 -1 +5 = 0 yes, x = -1 is a rational zero
5 and -5 don't work either so we're left with
Final answer: x = -1
Answer:
No
Step-by-step explanation:
It is not a function because the x should never repeat the y can but not the x.
