y=2x+3
to find inverse swap x and y
x=2y+3
x-3=2y
y=(x-3)/2
y=(x/2)-(3/2)
The inverse is f^-1(x)=(x/2)-(3/2)
Hope it helps!
Yes 1 5/7 and 4 2/7 is a solution. Adding those two numbers equals 6 because 5/7 + 2/7 = 1, then you have 4 + 1 +1 = 6
Two other solutions to x + y = 6 are any combinations of numbers when added together equal 6.
x = 5, y = 1
and
x = 2, y = 4
The explicit formula would be
This is a geometric sequence, since each term is found by multiplying the previous term by a constant. The explicit form of a geometric sequence is given by
where r is the common ratio, or constant we multiply by, and g₁ is the first term. For our sequence, g₁ = 5 and r = 3, so our formula is
Answer:
Step-by-step explanation:
Given:
Distribute the parenthesis
Subtract both sides by 4
Divide both sides by 2 to get alone
