Consider the quadratic equation ax^2+bx+5=0, where a, b, and c are rational and the quadratic has two didstinct zeros if one zor
erica [24]

Answer:

It can either be rational or irrational

Step-by-step explanation:

Given the quadratic equation ax²+bx+5 = 0, to get the zeros of the function, we will factorize the function to have;

ax²+bx = -5

x(ax+b) = -5

x = -5 and ax+b = -5

From the second function we have;

ax+b = -5

ax = -5-b

x = -5-b/a

This shows that the other value of x can be rational or irrational depending on the values of a and b

If there are 15 pistachios for every 5 bowls, how many pistachios are in 4 bowls
Pani-rosa [81]

Answer:

12 pistachios

Step-by-step explanation:

We need to find the unit rate. So we divide 5 from 15.

15/5=3

So we know that 1 bowl has 3 pistachios(which I think needs more).

Now we need to find how many pistachios are in 4 bowls. Which means we multiply 4 and 3.

4x3=12

So there are 12 pistachios in 4 bowls.
