Rewrite the fractions to have a common denominator to find the difference:
2/3 = 4/6
Difference = 4/6-5/6 = -1/6
Sequence formula = an = a1 + d(n-1)
A1 is the first term 5/6
And d = -1/6
Sequence = 5/6 -1/6(n-1)
Simplify to get an =(-n +6)/6
Answer:
Step-by-step explanation:
I think in this question we have to find slope, if so, its y = 10x.
to find the slope just pick two numbers, i chose (2,20) and (7,70) and then put them in the slope formula y2-y1/x2-x1. That gave me 10. I hope its correct. :)
X = unknown number
10x - 16 = 2x
Subtract 10x from both sides to isolate the variable on the right side of the equation.
-16 = -8x
Divide both sides by -8 to get x alone.
2 = x
Answer:
-9x + 3
Step-by-step explanation:
You would distribute first.
− ( x + 3 ) − 2 ( 4x − 3 ) → -x − 3 − 8x + 6
(If you see a negative sign in front of a parenthesis without a number, its usually a negative 1)
From there, you would combine like terms.
-x − 3 − 8x + 6 → -9x + 3
