Answer:
g = 8
Step-by-step explanation:
3g - 6 = 18
<u> +6 +6</u>
3g = 24
divide by 3
g = 8
Answer:
y= −1/2x+ 1/2
Step-by-step explanation:
Find the negative reciprocal of the slope of the original line and use the point-slope formula
y-y1=m(x-x1) to find the line perpendicular to y=2x−3.
The first term in our arithmetic sequence = 13
The common difference of our arithmetic sequence = 17 - 13 = 4
The formula for finding an equation for any arithmetic sequence is a(n) = A + B(n - 1)
A = the first term
B = the common difference.
Let's plug our numbers in.
a(n) = 13 + 4(n - 1)
Let's check to make sure we're correct.
a(1) = 13 + 4(1 - 1) = 13 + 4(0) = 13 + 0 = 13
a(2) = 13 + 4(2 - 1) = 13 + 4(1) = 13 + 4 = 17
That verifies that our formula is correct.
In conclusion,
a(n) = 13 + 4(n - 1)
