Answer: its the second anwser
Step-by-step explanation:
you have to subtract 40 on each side, then you have to divide by -8 on each side so that x is by itself, and then you have to flip the symbol because you divided by a negative.
All we have to do to find the solution to the system of equations represented by the given graph is find the two lines' intersection point. Here, we can see that the two lines intersect at the point (3, 4). Hence, the solution to the systems of equations is (3, 4). Hope this helps!
Answer:
B)
Step-by-step explanation:
Given f(x) = ( 7 - 8x )²
let f(x) be y,
y = ( 7 - 8x )² .............to find inverse we have to make x the subject.
±√y = 7 - 8x
-8x = √y - 7
x = (±√y - 7 ) / -8
Then,
Inverse of ( 7 - 8x )² is and is a function.
Answer:
Number of apartment = 9
Step-by-step explanation:
Given the ANOVA result :
ANOVA ____ df ____ SS
Regression __ 1 ___ 41587.1
Residual ____ 7 ___
Total _______ 8 __ 51984.5
Number of apartment building in sample (n) :
Degree of freedom (df) = n - 1
The degree of freedom = total = 8
Hence,
8 = n - 1
8 + 1 = n - 1 + 1
9 = n
Hence, number of apartment building in sample = 9
Answer:
A) 2:6=5:15
Step-by-step explanation:
2:6=1/3
5:15=1/3 then
2:6=5:15(=1/3)
