Graph the system of equations. then determine wheather the system has no solution, one solution, or infinitely many solutions. I

dimaraw [331]

Answer:

See below in bold.

Step-by-step explanation:

If we add the 2 equations we eliminate x and we get 2y =2.

So y = 1.

Substituting y = 1 in the second equation 1 = x - 3.

So x = 4.

A. One solution: (4, 1).

If we drew a graph we would have 2 lines which intersect at the point (4, 1).

Answer:

7

Step-by-step explanation:

hey there,

< Here's how you do subtraction in fractions!

Make sure you find a least common denominator. Here, it's given to you to be 15. Usually, you can just multiply the two denominators but then it would be quite large at times, so you kind of just have to guess.

How did they go from $\frac{4}{5} x-\frac{1}{3} x$ to $\frac{?}{15} x$ ?

Well, they used a least common denominator. 5 was multiplied by 3 to create 15, and 3 was multiplied by 5. But when you multiply the bottoms, you have to multiply the tops of the fraction too (the numerators).

So 4/5x was multiplied by 3. Denominator turned out to be 15, and now the top is 4x3 = 12. So the fraction is 12/15.

1/3x, on the other hand, was multiplied by 5. Denominator was also 15 so they're the same, and top is 1x5 = 5. So the fraction is 5/15.

Now, let's put them together.

$\frac{12}{15}x-\frac{5}{15} x$

When subtracting x, the x just stays there, so if it was 10x-4x, the answer would've been 6x. So now let's subtract!

12-5 = 7, and the denominator stays the same.

The answer is $\frac{7}{15} x$ . So the numerator, or answer to your question, would be 7.

Hope this helped! Feel free to ask anything else.

Before leaving a particular restaurant, patrons are asked to respond to a questionaire containing the questions given below. For

patriot [66]

Answer:

1. Nominal Scale; 2. Ordinal Scale; 3. Ordinal Scale; 4. Nominal Scale.

Step-by-step explanation:

The variable in Question 1 (Q1) could be described as The attributes of the restaurant, with possible values: service, prices, quality of food, menu options (four values).

The variable in Question 4 (Q4) could be mentioned as Eaten before in the restaurant, with possible values: yes or not (two values).

These values are, in fact, simply names, and although they can be represented using numbers, they have no numerical meaning at all.

For instance, the values in Q1 can be labeled by 0 (service), 1 (prices), 2 (quality of food), 3 (menu options) and 0 (not) or 1 (yes), in Q4; for purposes of data analysis, 3 (menu options) is a label and does not mean a higher score than 1 or 0. These numbers are labels rather than meaningful numbers, and this is a characteristic of the Nominal Scale of measurement. Then, the possible response for questions Q1 and Q4 is the Nominal Scale.

The variable in Q2 is the Rating of the restaurant, with possible values: excellent, good, fair, poor.

The variable in Q3 is Prices, with possible values: high, average, low.

As can be seen, any possible value in either question, like excellent or high, has a greater value than fair or low, respectively. In other words, they have different values concerning others, but we do not the distance among them. High is greater than Average, and the latter is greater than the Poor value, but we do not know what distance separates one value from the other, and this is a characteristic of the Ordinal Scale of measurement. Thus, the possible response for questions Q2 and Q3 is the Ordinal Scale.

Which value for x makes the sentence true? 1/10 + x = 1/7

alexandr1967 [171]

Answer:

3/70

Step-by-step explanation:

change 1/10 and 1/7 so the denominator (bottom number) is the same. 1/10= 7/70 and 1/7= 10/70 so you need 3/70 to make the two numbers equal.
