3y=15x-12

How to solve for y?

Answers

Answer 1
Answer: first you divide both sides by three.

3y=15x-12
/3    /3  /3

y=5x-4

y cannot be solved in this equation, but you should get y by it self.
Answer 2
Answer: have to isolate the variable. divide everything by 3 so the problem would now be y=5x-4

Slope
y = ⁸/₉x - 3¹/₃
The slope is ⁸/₉.

Y - Intercept
y = ⁸/₉x - 3¹/₃
y = ⁸/₉(0) - 3¹/₃
y = 0 - 3¹/₃
y = -3¹/₃
The y-intercept is -3¹/₃

The answer is C.

Answer:

C. The slope is 8⁄9 and the y-intercept is -3⅓ [or -10⁄3].

Step-by-step explanation:

According to the Slope-Intercept Formula, y=mx+b,bis your y-intercept, so that is a giveaway. Now, your rateofchange[slope], which is represented by m,is the coefficient, meaning the term in front of x,so that is also a giveaway.

The decimal number 1.2057 is greater than the decimal number 1.1421. Then the correct option is A.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The decimal numbers are given below.

1.2057 and 1.1421

Compare the decimal numbers, then we have

1.2057 > 1.1421

The decimal number 1.2057 is greater than the decimal number 1.1421. Then the correct option is A.

Widal Kit Salmonella Ha, Hb, Hc, Hd, OA, OB, OC, OD

Rapid Labs Widal antigen set contains ready to use concentrated smooth antigen suspensions of the bacilli; S. typhi ‘O’. S. typhi ‘H’. S, paratyphi ‘AO’. S. paratyphi ’BO‘. S. paratyphi ’AH’, S. paratyphi ‘BH’. S. paratyphi ‘CH’. S. paratyphi ‘CO’ and/or polyspecific positive control reactive with these antigens.

When the Widal antigen suspensions are mixed and incubated with the patient’s serum, anti salmonella antibodies present in the patient serum react with the antigen suspensions to give agglutination. Agglutination is a positive test result, indicating presence of anti-salmonella antibodies in the patient serum. No agglutination is a negative test result indicating absence of anti-salmonella antibodies.

Pack size – 8 x 5ml

Need help with a problem. For some reason I can not seem to get it correct. Thinking my formula is wrong. Here's the problem:Assume that there are approximately 140x10^9 stars in our galaxy.
Our galaxy is 50,000 light years from the center to the edge, but just 1,000 light years thick. It's shaped like a thin disk or cylinder. If the stars were distributed equally throughout the galaxy, how many stars would you expect to find in one cubic light year?

I thought it would be Pi*r^2*l. Then divide that by the number of stars. What am I doing wrong? Thanks, been 20 years since I had to do math like this!
