What best describes how many real number solutions the equation has?

Mathematics
1 answer:
DerKrebs [107]3 years ago
7 0

Answer:

zero, because the discriminant is negative

Step-by-step explanation:

By writing the quadratic formula, we have the discriminant written in the root as;

b^2-4ac

Now, given the expression, we can see that the discriminant here is -19

What this mean is that we have a negative discriminant

Hence, we can conclude that the roots are complex and as such, none of the roots are real

Linear equations for Pre-IB Algebra 2. Solve for s, R(s + t) = st.
Anastaziya [24]

R(s + t) = st

Rs + Rt = st

Rs - st = -Rt

s ( R - t) = -Rt

*s = - Rt / (R - t) Multiply through by -1 on the right.

*s = Rt / (t - R) Put in the brackets in your answer. What you have been writing means

s = Rt/r - R you need the brackets. The stars mean that either could be an answer. I think your problem could be the brackets. Now I'm reasonably certain this is correct.

Sergio039 [100]

Answer:

Step-by-step explanation:

The ratio of height to shadow length will be proportional.

2.6 / 1.26 = h / 37.25

h = 37.25(2.6)/1.26 = 76.865079...

h = 76.9 m

Which graph represents y = √ X
Orlov [11]

Explanation:

\displaystyle [9, 3] → 3 = \sqrt{9} \\ [4, 2] → 2 = \sqrt{4} \\ [1, 1] → 1 = \sqrt{1} \\ [0, 0] → 0 = \sqrt{0}

**In this case, we want NON-NEGATIVE terms.

I am joyous to assist you at any time.
