Math question: Solve for y: 2x-y=3

Answers

Answer:

[tex]y=2x-3[/tex]

Step-by-step explanation:

This is just algebraic manipulation. In order to solve for y, you need to isolate it. Start this by moving the 2x from the left side of the equation. You can do this by subtracting 2x from both sides and you should end up with:

[tex]-y=-2x+3[/tex]

After this, you still have a negative y, which means you just need to divide both sides of the equation by -1 to get rid of the negative. That should reverse the signs of all the variables in the equation, making it look like:

[tex]y=2x-3[/tex]

Martha rolls a 6 sided number cube (number one through six) two times. What is the probability she will roll a 3 both times?

Answers

Answer:

2/12

Step-by-step explanation:

since there are six sides, rolling twice will give you a total of 12 possibilities, each time, you have 1 chance out of 6 each time to roll 3

1/6 + 1/6 = 2/12

If you want to, or need to reduce 2/12, divide both the numerator and denominator by two, and you will get 1/6 again.

Evaluate the finch beaks shown in the picture. Choose ALL of the statements that correctly explain the evolution of finch beaks. A) As the environment changed, the finches grew longer beaks to allow them to get food out of fruits. B) Finches with longer beaks settled on the same island with smaller beaked birds. Over time, they bred, producing medium beaked birds that became more common in the population. C) There are finches with different types of beaks in the population. During a drought, those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait on to offspring. D) A random mutation introduced the shorter, thicker beak into the population. However, those with thinner, longer beaks were better able to get nectar from the island's flowers. Those birds with the shorter, thicker beaks were unable to get enough food to survive. E) A disease swept through the island killing many of the insects that were common on the island, leaving the birds who ate insects from the ground starving. The finches that had thicker beaks and could get food from tree bark were able to continue to survive and reproduce, increasing this trait in the population. 13. Jessica has taken 8 quizzes.
