Solve 6x-3y=-6 for y

Answers

Answer 1
Answer:

Answer:

y = 2x + 2

Step-by-step explanation:

6x -3y = -6 (get y on one side of the equals sign by substracting 6x from both sides)

-3y = -6x - 6 (divide each side by -3 to get final value of y)

y = 2x + 2

Answer:

Second diagram

Step-by-step explanation:

Basically, for any of these options to be functions, each value in the domain must correspond to only one value in the range.  So any option that has a value in the domain section with arrows pointing to multiple values in the range section is not a function, and not our answer. We must look for the option where there is only one range value for each domain value. So our answer is the second option.

Mr. Ishimoto ordered x new math books and y new workbooks for his class. The total weight of the box of books cannot be more than 50 pounds. If each math book weighs 3.2 pounds and each workbook weighs 0.8 pounds, which inequality represents the maximum number of each type of book that can be shipped in a single box?

Answers

Answer:

3.2x + 0.8y ≤ 50

Step-by-step explanation:

Mr. Ishimoto ordered math books and workbooks for his class.

Weight of each math book = 3.2 pounds

number of math books ordered = x

so, total weight of math books = 3.2x

Weight of each workbook = 0.8 pounds

number of workbooks ordered = y

so, total weight of workbooks = 0.8y

Since the total weight of the box of books cannot be more than 50 pounds, the equation would be

3.2x + 0.8y ≤ 50

Answer: B

A 26‘long painting is how many yards long?

Answers

Hello! 

If a painting is 26 feet long, it's 8 and 2/3 yards long.

This is because there is 3 feet in a yard. You would do 26 divided by 3. You would get 8 yards and have 2 feet left. Obviously 2 feet is smaller than a yard, so it'd be 2/3 of a yard. Therefore the answer is 8 and 2/3 yards.

Hope this helped! :)
