0 A public beach in Arkansas charges non- residents $12 per day for a fishing license and $3.50 per day for live bait. Arkansas

vfiekz [6]

Non Residents:
f(x)= money in $ paid.
x=number of days.

f(x)=x(12+3.5)=15.5 x

f(x)=15.5x

Arkansas residents
f(x)=money in $ paid.
x=number of days.

f(X)=x+174

Now, we equate functions:

15.5x=x+174 (this is the equation)
15.5x-x=174
14.5x=174
x=174 / 14.5=12

Answer: the number of days is 12 days. The ecuation has one solution, because when I has solved it, I have had one solution.

So:

Prob(Drawing a white then a red marble) = 2/3 * 1/2

= 2/6

= 1/3.

Change the line 3x − 8y = 5 into slope-intercept form.

Nimfa-mama [501]

Slope is y=mx+b
m=slope
b=y intercept

solve for y basically

3x-8y=5
minus 3x both sides
-8y=-3x+5
divide both sides by -8
$y=\frac{3}{8}x-\frac{5}{8}$
