Find the value of k such that the system of equations does not have a solution:

Answer:

k = -6.

Step-by-step explanation:

We need to  make the left side of the second equation a multiple of the left side of the first one.

We can do this by making k = -6  ( because -15/10 = -6/4).

The second equation becomes

-15x - 6y = 14

Now multiply this by -2/3. We get

10x + 4y =  -28/3

but the first equation is 10x + 4y = -3 .

So there are no solutions.

So the answer is k = -6.

DerKrebs [107]
Using a binomial distribution considering there's a 30% chance it will rain on any of the three days: 

<span>The probability of it raining on 0 days is (1)(0.7)(0.7)(0.7) = 34.3%. </span>
<span>The probability of it raining on 1 day is (3)(0.3)(0.7)(0.7) = 44.1%. </span>
<span>The probability of it raining on 2 days is (3)(0.3)(0.3)(0.7) = 18.9%. </span>
<span>The probability of it raining on 3 days is (1)(0.3)(0.3)(0.3) = 2.7%. </span>

<span>There's a 65.7% chance that it will rain at least once over the three-day period.</span>

Which proportion can be used to show that the slope of AC is equal to the slope of CE?
Gnesinka [82]

Slope is given by the expression:

m=\frac{y_2-y_1}{x_2-x_1}

We can equal both slopes of mAC and mCE

\begin{gathered} \frac{3-6}{-1-(-3)}=\frac{-3-3}{3-(-1)} \\  \\ \frac{-3}{2}=-\frac{6}{4} \\ -\frac{3}{2}=-\frac{3}{2} \end{gathered}

Answer is B.

PLEASE<br> Need Help<br> Show Work
BartSMP [9]

This set notation really seems the hard way to exclude a single value. Anyway...

The domain doesn't include where the denominator is zero, 4x + 7 = 0,

x = -7/4

The range doesn't include the asymptotic value, which is

y=2x/4x = 1/2

So we need domain x ≠ -7/4 and range y ≠ 1/2

Answer: First choice
