Help me please i do not understand it.

Answer:y = 2x + 4

Explanation:

1) The slope - intercept form is of the kind y = mx + b, where m is the slope and b is the y-intercept.

2) Given two points you can find the slope (using the two points) and then the equation using one of the points.

3) slope = m = Δy / Δx

points given (3,10) , (0,4)

m = [y2 - y1] / [x2 - x1] = [10 - 4] / [3 - 0] = 6 / 3 = 2

4) equation

y - y2
-------- = m
x - x2

  y - 4
---------- = 2
  x - 0

=> y - 4 = 2 (x - 0)

y - 4 = 2x

y = 2x + 4

salantis [7]

Answer:

  • Three beers.

Step-by-step explanation:

The first mathematician orders 1 beer, the second orders 1/2 a beer, the third orders 1/4 a beer, the fourth orders 1/8 a beer, the fifth orders 1/16 a beer. . .

  • The Sequence is: 1,\frac{1}{2}, \frac{1}{4}, \frac{1}{8}, \frac{1}{16} \cdots
  • On observation, the next term is derived through the division of the previous term by 2.
  • 2 is the constant factor
  • Therefore, the bartender says 'Fine, I’ll just pour you two beers.'

Therefore, if the first mathematician orders 6 beers, the second orders 2 beer, the third orders 2/3 a beer, and so on

  • The sequence is 6,2,\frac{2}{3}, \cdots
  • On observation, the next term is derived through the division of the previous term by 3.
  • 3 is the constant factor
  • Therefore, the bartender should pour three beers.

rashid can paint 2 square feet of fence in 10 minutes how long will it take him to paint a fence 6 feet high by 25 feet long
Stells [14]
The area of the fence is 6*25=150 square feet.
It will take him 150 / 2 = 75 of 10-minute intervals. 75 min *10 = 750 min = 750/60 hours = 12.5 hours.
