1. B A C
Reason:
A: 4
is 12.6
B: the Square root of 18.7 is 4.32
2. a
Reason: the square root of 80 is 8.9, thus closest to 9 from all the others.
3. C
Reason: 6/7 = 0.86, and the square root of 3/4 = 0.87
Answer: Option 2
Step-by-step explanation:
Divide 15 by 3 and substract the variables's exponents.
Solve;
or
The equation is f(x) =(x-6*(x+6))/(x^2 - 9).
For the vertical asymptote test in a rational function. The denominator is first set to zero.
x^2 - 9 = 0
x^2 = 9
x = +-3
The values for x are then substituted to the numerator.
x=3; x-6(x+6) = 3-6(3+6) = -51
x=-3; x-6(x+6) = -3-6(-3+6)= -21
The zeros of the denominator do not make the numerator zero so the vertical asymptotes are x= +-3
In first question x=8, I’m too lazy to solve the rest
You can cross-multiply to convert fractions into percentages.
1 x
— = —
8 100
(100)1 = x(8)
100 = 8x
Isolate x by dividing both sides of the equation by 8.
100 8x
— = —
(8) (8)
100
— = x
8
Simplify.
12.5 = x
So one out of eight equals 12.5 out of a hundred, or
12.5 %
