Well do u know how many there are?
Slope 2/1, y intercept is 6, equation is f(x)=6-2x
It’s a left side 8’5 right????
Let x be the first number
Let y be the second number
x+y=61
x-y=37 --> x=37+y
(37+y)+y=61
37+2y=61
2y=61-37
2y=24
y=12
x+y=61
x+12=61
x=61-12
x=49
Therefore the numbers are 49 and 12
Hope I helped :)
3 x -2^(n-1)
To answer this question, first solve the equation 3 x -2^(n-1) for n=1, n=2,
n=3, n=4, and n=5.
Where n=1
3 x -2^(1-1)
3 x -2^0
3 x 1
n1 = 3
Where n=2
3 x -2^(2-1)
3 x -2^1
3 x -2
n2 = -6
Where n=3
3 x -2^(3-1)
3 x -2^2
3 x 4
n3 = 12
Where n=4
3 x -2^(4-1)
3 x -2^3
3 x -8
n4 = -24
Where n=5
3 x -2^(5-1)
3 x -2^4
3 x 16
n5 = 48
The next step is to find the summation by adding n1 + n2 + n3 + n4 + n5.
3 + (-6) + (12) + (-24) + (48) =
3 - 6 + 12 - 24 + 48
= 33
The answer is C. 33
