The system won't have a unique solution when what appears to be two lines is really only one line. The coefficients in an equation for a line only matter in ratio; if we multiply them all by the same non-zero scalar we'll still have the same line, of course with an infinite number of points on it, our infinite number of solutions.

2x - y = 8

6x - 3y = 4a

We need these to be the same equation, meaning they have to have all the same solutions. So we have to figure out the factor to multiply the first equation by to get the second.

That factor is obviously 3 because 3(2x)=6x and 3(-y)=-3y. So we need the constants in the same ratio,

3(8) = 4a

24 = 4a

a = 6

Answer: B. 6

Answer:

Step-by-step explanation:

1.2*8=16

16-8=8

Several paint mixtures are made by mixing blue paint and white paint. Paint Colors Blue Paint White Paint Mixture A 5 cups 12 cu

Flura [38]

The correct answer is option B which is mixture B will have the highest ratio of blue paint.

<h3>What is a ratio?</h3>

In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.

<h3 />

The given ratios are:-

Mixture A = $\dfrac{5}{12} = 0.41$

Mixture B = $\dfrac{6}{6}= 1$

Mixture C = $\dfrac{4}{12}= 0.33$

Mixture B = $\dfrac{5}{6}=0.83$

Here the ratio of mixture B is the highest among all the options available.

Therefore the correct answer is option B which is mixture B will have the highest ratio of blue paint.

Statistics show on average an adult person receives 425 pieces of mail each year with a standard deviation of 50. What are the m

Kisachek [45]

Answer:

The answer is 60.11

Step-by-step explanation:

An adult person receives 425 pieces of mail each year with a standard deviation of 50.

Now, we have the following details :

Mean of sample = 425

sigma = 50

Standard error = $\frac{425}{\sqrt{50} }$

= $\frac{425}{7.07}$ = 60.11

Suppose you add two vectors A and B . What relative direction between them produces the resultant with the greatest magnitude? W

Anna71 [15]

Answer: The resultant would be the sum and the difference between the vectors.

Step by step explanation: 1. The possible resultant is between the sum of the 2 vectors and the difference between the two vectors.

2. The greatest magnitude is when the vectors lie in the same direction and the sum would be the scalar sum of the two vectors. The angle between the two would be zero degree.
