f(x) = -6x + 9
g(x) = 6x - 17
These lines are neither parallel or perpendicular
Here's a graph to show this : https://www.desmos.com/calculator/eqamgrdkuc
We actually need to include an absolute value here, because the "x" under the radical could be negative......so........the complete answer is 7 l x^3 l
( 5 + 3/4) (2/6)
Convert the mixed number to an improper fraction
5 + 3/4 = 23/4
And 2/6 = 1/3 so we have
(23/4) (1/3) =
23 / 12 = 1 + 11/12
(4/5) (5/8) (3/4)
And we can rearrange numeratos and denominators thusly :
(4/4) (5/5) (3/8) =
1 * 1 * 3/8 =
3/8
2x < 12 divide both sides by 2
x < 6

The total circumference of the circle is given by:
2* pi * (d/2) = pi * d where d is the diameter........so we have
pi * 7 = about 22 ft
So.....the unit price per foot =
176 / 22 = about $8 per foot
2W^2 - 11W = -12 add 12 to both sides
2W^2 - 11w + 12 = 0 factor as
(2W - 3) (W - 4) = 0
Set each factor to 0
2W - 3 = 0 W - 4 = 0
add 3 to both sides add 4 to both sides
2W = 3 W = 4
divide both sides by 2
W = 3/2
And those are the two solutions
Nice job, HSC....!!!!
