Hi I really need help with this question please,
Mrrafil [7]

Answer:

{ ( \sqrt{30 - x} )}^{2}  =  {x}^{2}  \\ 30 - x =  {x}^{2}  \\  \\  {x}^{2}   +  x - 30 = 0 \\ delta = 1 - 4 \times ( - 30) \times 1 = 121 \\ x1 =  \frac{ - 1 +  \sqrt{121} }{2 \times 1}  =  \frac{ - 1 + 11}{2}  = 5 \\ x2 =  \frac{ - 1  -   \sqrt{121} }{2 \times 1}  =  \frac{ - 1  -  11}{2}  =  - 6 \\

Use quadratic regression to find
vovangra [49]

Answer:

y = 6x² -13x -5

Step-by-step explanation:

(1,-12) (2,-7) (5,80)

y = ax² + bx + c

-12 = a*1² + b*1 + c = a+b+c    (1)

-7 = 4a + 2b + c    (2)

80 = 25a + 5b + c   (3)

(2)-(1): 3a + b = 5    (4)

(3)-(2): 21a + 3b = 87   (5)

(4)*3:     9a + 3b = 15    (6)

(5)-(6):  12a = 72      a = 6

(4)                             b = -13

(2)                             c = -5

Can anyone help me?​
suter [353]

Answer:

0.8

Step-by-step explanation:

3(5x+2)+10=4

=15x+6+10=4

After this step you subtract 6 from each side and then subtract 10 from each side and then after that you divide 15x on each side which will give you 0.8.
