Answer:
-x^2 +9x -2
Step-by-step explanation:
f(x) = – x^2 + 6x - 1 and g(x) = 3x
- 1,
(f + g)(x) = f(x) + g(x)
= – x^2 + 6x - 1 + 3x
- 1
Combine like terms
= -x^2 +9x -2
I don't know 30 I couldn't see the question that well
You have to start with the parenthesis. 140-68=72. (remember to use pemdas parenthesis, exponent, multiplication, division, addition, and subtraction. Then you do 32-72/9=24. 240/8=30. 30-24=6. 6 is the answer.
Answer:
A. (-2.28, 3.38)
Step-by-step explanation:
The confidence interval of the slope :
b ± Tcritical*SE
Tcritical at 95%, df = n - 2 = (15 - 2) = 13
Tcritical = 2.160369
b = slope Coefficient = 0.54924
S.E = 1.311
Hence, we have :
Confidence interval = 0.54924 ± (2.160369 * 1.311)
Confidence interval = 0.54924 ± 2.832243759
Lower boundary = 0.54924 - 2.83224 = - 2.283
Upper boundary = 0.54924 + 2.83224 = 3.3814
The answer option is A. (-2.28, 3.38)
