How do you solve for the central area of a polygon?
ycow [4]

Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.

  2. There are more yellow marbles than blue marbles, so it's actually more likely that you'll pick a yellow one, rather than the blue one.
  3. The probability of picking a green marble is given by the number of green marbles divided by the total number of marbles. Compute this ratio and see what you get.
  4. Similarly, the probability of picking a black marble is given by the number of black marbles divided by the total number of marbles. There are no black marbles, so...

What is the slope and y-intercept in the equation y = 5x - 7?
grin007 [14]

Answer:

Slope: 5

y-intercept: -7

Step-by-step explanation:

Slope-intercept form is written as 'y=mx+b', (x,y) being any point on the line, m its slope, and b the line's y-intercept.

y=mx+b

y=5x-7

In this equation, m=5, and b=-7.
