Answer:
-1
f (x) = -3(x + 5)
Step-by-step explanation:
1) in f(x) = 1/3x-5, replace f(x)= with y= as follows: y = (1/3)x - 5
2) interchange x and y, obtaining: x = (1/3)y - 5
3) solve this result for y: (1/3)y = -x - 5, or -(x + 5). Next, multiply both sides by 3 to eliminate the fraction (1/3): y = -3(x + 5)
4) replace y with the symbol for "inverse of f(x);
-1
f (x) = -3(x + 5)
Answer:
Division
Step-by-step explanation:
You divided both sides of the inequality by -3. Multiplying/dividing by negative numbers change the sign of the inequality, so you have ">" turned into "<".
Answer:
7x-17y
Step-by-step explanation:
We need to find the expression which represents the difference when (-2x+10y) is subtracted from (5x−7y) . Let the result is R.
So,
R = (5x−7y)-(-2x+10y)
Solving brackets as follows :
R = (5x−7y)+2x-10y
taking like terms together
R = (5x+2x)+(-7y-10y)
R = 7x-17y
Hence, when (-2x+10y) is subtracted from (5x−7y) the result is (7x-17y).
Its kinda the same as the A just in the negative
Answer:
D The null hypothesis is not rejected because 0.25 > 0.05. There is not sufficient evidence to suggest that there is a linear relationship between a wheat stalk's height and its yield.
Step-by-step explanation:
Given the hypothesis :
H0 : β1 = 0
Ha : β1 ≠ 0
The Pvalue = 0.25 ; α = 0.05
Decision region :
Reject H0 ; if Pvalue < α
Comparing the Pvalue and α - value
0.25 > 0.05
Here, the Pvalue is > α ; hence, we fail to reject the Null, H0
Hence, there is no significant evidence to suggest that there is a linear relationship between what's stalk height and its yield.
