Answer:
1. Find the equation for the line that passes through (−2,9) that has slope 7/3 Give your answer in point-slope form. You do not need to simplify. 2. Find the equation of the line with slope = -4 and passing through (-6,29). Write your equation in the form y= 3. Find the equation for the line that passes through the points (7,−4) and (4,9). Give your answer in point-slope form. You do not need to simplify.
Step-by-step explanation:
A₆ =12
a₇ = ?? = x
a₈ 27
In this case x is the geometric mean & as per the formula
geometric mean of 2 numbers =√(a₆ * a₈) = √(12*27)
& x=18.
Proof:
Find the common ratio between a₇ & a₆ ==> = ( x) / 12
now find the common ration between a₈ & a₇ ===> =27 / (x)
x/12 = 27/x ===> x² = 12*27 ==> x² = 324 & x =√324 = 18
