Hello :
s = <span> |−13| = 13
the </span> inequalitie is not true is ; r ≥ s means : (r > s ) or ( r = s)
(r > s ) : <span>is not true
</span> ( r = s) : is not true
Answer:
a n = -3+(n-1)-30
Step-by-step explanation:
-3 - 30 = -33
-33 - 30 = -63
-63 - 30 = -93
The common difference here is -30. d = -30
The explicit formula is a n = a1 + (n-1)d
Answer: 3/2y - 5
Step-by-step explanation:
Answer:
The bus travels 1.68 miles in one minute
Step-by-step explanation:
Make a proportion:
? = how far the bus travels
5 - 8.4
1 - ?
Solve: 8.4×1÷5= 1.68
one way is to solve for the invers of the first function
remembe, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with f⁻¹(x)
A.
f(x)=x/2+8
y=x/2+8
x=y/2+8
x-8=y/2
2x-16=y
f⁻¹(x)=2x-16
nope, not A
B.
f(x)=3x³+16
y=3x³+16
x=3y³+16
x-16=3y³
(x-16)/3=y³
∛((x-16)/3)=y
f⁻¹(x)=∛((x-16)/3)
nope, not the same
not B
C.
f(x)=18/x-9
y=18/x-9
x=18/y-9
x+9=18/y
y(x+9)=18
y=18/(x+9)
f⁻¹(x)=18/(x+9)
correct, the answer is C
answer is C
