Answer:

14 and 4/1000 or 14004/1000

Step-by-step explanation:

1*10+3*1+4*(1/1000)

First i like to separate the equation by PEMDAS or order of operations. First is parentheses, which is the fraction. Then is exponents. There is none. Then multiplication and division so u solve 1*10, 3*1 and 4*1/1000.

This is the updated equation: 10+4+(4/1000)

Next you do subtraction and addition. The order does not matter if there's only addition. If there is subtraction u solve by the order of the equation. SO in this step we solve 10+4+(4/1000)

Here is the updated version: 14+(4/1000)

Then u add that which is 14 and 4/1000 or you can do 14004/1000

PLEASE HELP ME FAST!!!! ( It's about y-intercept)
Hoochie [10]

Answer:

y = 6x -7

Step-by-step explanation:

1. The equation of any line in slope-intercept form is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. Given that the slope is 6, we plug that value in m, and given that the y-intercept is -7, we plug that value in b:

  • y = mx + b
  • y = 6x - 7
