5. How many solutions does this system of equations have?

Diano4ka-milaya [45]

Answer:

$\text{\boxed{\sf{D. \ No\ solution}}}$

Step-by-step explanation:

Isolate the term of x and y from one side of the equation.

First, you have to substitute of y=-4x-1.

$\Longrightarrow: \sf{[-4x-1=-4x-9]}$

<u>Add by 4x from both sides.</u>

$\Longrightarrow: \sf{-4x-1+4x=-4x-9+4x}$

<u>Solve.</u>

$\Rightarrow:\sf{-1=-9}\\\\\Rightarrow: \sf{(-9)-(-1)=-9+1=-8}\\\\\Rightarrow: \sf{8=0}$

<u>Therefore, the correct answer is "D. No solution".</u>

I hope this helps. Let me know if you have any questions.

The probability is a chance of an event happening. The probability of assured event is 100% or 1.

If there is no chance of an event happening the probability is zero (0).

The probability of snowing = 0.29

The probability of not snowing = 1 - 0.29

= 0.71
