Is the system of equations is consistent, consistent and coincident, or inconsistent? y=4x−4y=−4x+4 Select the correct answer fr
Luba_88 [7]

Answer: It is consistent as the lines are intersecting lines and it has a unique solution

Step-by-step explanation:

Since we have given two systems of equation :

y=4x-4\\\\and\\\\y=4x+4

We need to check whether the system of equations is consistent or inconsistent.

As we know the formula for checking the consistency :

\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}

In first equation we have

y=4x-4\\\\4x-y=4\\\\Here,a_1=4,b_1=-1,c_1=4

similarly,

In the second equation we have

y=-4x+4\\\\4x+y=4\\\\Here,a_2=4,b_2=1,c_2=4

So, According to question, we have

\frac{1}{4}\neq \frac{1}{-1}\neq \frac{4}{4}\\\\0.25\neq -1\neq 1

Hence, it is consistent as the lines are intersecting lines and it has a unique solution.

If a fair die is rolled 3 times, what is the probability, to the nearest thousandth, of
seropon [69]

Answer:

0.347

Step-by-step explanation:

n = 3

p = 1/6

r = 1

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

P = ₃C₁ (1/6)¹ (5/6)³⁻¹

P = 0.347

Or, using a calculator:

P = binompdf(n, p, r)

P = binompdf(3, 1/6, 1)

P = 0.347
