Answer:

4 ÷ 10

Step-by-step explanation:

The computation of P is shown below:

If we add two marbles i.e.

= 4 + 6

= 10 marbles

Now if we draw the second marble

P(blue) = Blue marbles ÷ total marbles

= 4 ÷ 10

In the other case

P( blue second given a green first) = 4 ÷ 10

Write the equation of a line perpendicular to y=-2x+1 that passes through the point (2,3)
Cloud [144]

Answer:

y = 1/2x + 2

Step-by-step explanation:

First you have to determine the slope which is the opposite reciprocal of the slope of the line given.

So we take the slope -2 and reciprocate and by flipping the numerator and denominator which makes it -1/2.

Then we have to make it the opposite, like making a negative into a positive or a positive into a negative. So that would make it positive 1/2.

We now have the slope which is 1/2 and not we have to make sure it goes through point (2,3).

To do that, we must adjust the y-intercept until it goes through that point. We result in getting the y-intercept of 2.

The answer is y = 1/2x + 2

Answer: For number 1 tell Andre no.

Step-by-step explanation: This is because he wants to make a scaled copy of Jada's drawing but by turning 4 into 8 by adding, it will create consistences to the point the best way to scale would be to multiply. So, Tell Andre that if he wants 4 to be 8, he should multiply instead of adding. Very epic!
