Plz statements are true about the ordered pair (−4, 0) and the system of equations? {2x+y=−8x−y=−4 select each correct answer. the ordered pair (−4, 0) is a solution to the first equation because it makes the first equation true. the ordered pair (−4, 0) is a solution to the second equation because it makes the second equation true. the ordered pair (−4, 0) is not a solution to the system because it makes at least one of the equations false. the ordered pair (−4, 0) is a solution to the system because it makes both equations true.

Use this data in the problem below. follow the steps carefully. round to the nearest tenth. lot 3: week 1: 345 week 2: 340 week 3: 400 week 4: 325 step 1. jim enters the data and calculates the average or mean. step 2. jim calculates the deviation from the mean by subtracting the mean from each value. step 3. jim squares each deviation to remove negative signs. step 4. jim sums the squares of each deviation and divides by the count for the variance. step 5. jim takes the square root of the variance to find the standard deviation.

Lorne subtracted 6x3 – 2x + 3 from –3x3 + 5x2 + 4x – 7. use the drop-down menus to identify the steps lorne used to find the difference.

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c
