Answer:  

y = 4x² -19x -5

y = 4x² -19x -5

(Quadratic regression = the process of determining the equation of a parabola that best fits a set of data)

Susie lost $15 on Monday. Her mom was upset, but gave her another $20. She lost another $13 today. Write an integer to represent
maria [59]

Answer:

Step-by-step explanation:

If you add 13 +15 you get 28$ if we were to write that as an integer out of 20 it would be 28/20 but as an improper fraction, it would need to  be simplified into  1 and 8/20  ( 1  8/20)

If you are looking how much she lost out of the 20 she lost today it would be 13/20

Hope this helps

7 + 22 x 4 - 31 = 85<br> This is for order of operations I don’t know how to do any of this
aniked [119]

Answer:

64

Step-by-step explanation:

7 + 22 × 4 - 31 = 64

How the answer is 64:

Use BODMAS (Bracket, Of, Division, Multiplication, Addition, Subtraction) for order of operation.

22 × 4 is first which is equal to 88

7 + 88 is next which is 95

95 - 31 is last which is 64.

The answer is 64, not 85.
