Answer:

y = 2x + 20

y\geq 20

x\geq 0

Step-by-step explanation:

Vlad spent 20 minutes on history. Then Vlad spent 2 minutes on each math problem for homework, this is 2x. So in total, he spent 20+2x on homework. Depending on how many problems he did, the total time y can be found. This is the equation 20+2x=y.

If Vlad did 0 math problems then he spent at least 20 minutes on homework from history. This is the constraint y\geq 20.

We also know Vlad can do many math problems but the least amount he did was 0, so the second constraint is x\geq 0.

List three numbers that are larger than 20 but smaller than 50 and only have 2 factor​
Vedmedyk [2.9K]

Answer: 20, 16, 45

Step-by-step explanation:

I'm not sure if we can use the number 20 but anyways here it is!

Factors:A factor is simply a number that is multiplied to get a product. Factoring a number means taking the number apart to find its factors.Factors are either composite numbers or prime numbers. A prime number has only two factors, one and itself, so it cannot be divided evenly by any other numbers.

I hope this helps!!

The pair of points lies on the same line with the given slope. Find x.
Darya [45]

Answer:

x = 6

Step-by-step explanation:

Find the equation of the line

y = mx + b

Use the slope given 3 and the x of 4 and the y of 11 from the point given (4,11)

11 = 3(4) +b   Solve for y

11 = 12 + b  Subtract 12 from both sides

-1 = b

y = 3x -1  This is the equation of the line.  Substitute in 17 for y and solve for x

17 = 3x -1  Add 1 to both sides

18 = 3x  Divide both sides by 3

6 = x
