Explanation:
Given:
−3x2+12x+1=0
This is in the form:
ax2+bx+c=0
with a=−3, b=12 and c=1
In order to decide which method to use, we can first examine the discriminant:
Δ=b2−4ac=122−4(−3)(1)=144+12=156
Since Δ>0 we can tell that the quadratic has 2 distinct real solutions, but because it is not a perfect square we can also tell that those solutions are irrational.
So there is no rational factorisation and we can discount the use of an AC method or similar.
We can use the quadratic formula or we can complete the square.
If we choose to use the quadratic formula, then we find:
x=−b±√b2−4ac2a
x=−b±√Δ2a
x=−(12)±√1562(−3)
x=−12±2√39−6
x=2±√393
When completing the square, note that b=12 is already divisible by a=−3 and by
Answer:
y=7.5x, y=60
Step-by-step explanation:
you have to consider x as the input and y as output
when input x=2 the output y=15 so it grew by 7.5 so we can say that y= 2*7.5
in general the equation is y= 7.5*x
when x=8 we will have y=7.5*8=60
Answer:
1:14
Step-by-step explanation:
1 with nuts
14 without nuts
The ration has to be: w:wo
So 1:14
