When given two points, use point-slope form
When given a point and the intercept, use slope-intercept form.
When given a point and the slope, use point slope form.
1) 1/5x + 3=0
1/5x=-3
x=(-3)(5)=-15
2)6x-7=0
6x=7
x=7/6=1.17
3) -8/3x+9=0
-8/3x=-9
-8x=-27
x=27/8=3.375
Answer:
$5.49
Step-by-step explanation:
Basically we can take the price of the bike, 137.32, and multiply by the tax, 0.04, to get 137.32*0.04 and we are left with 5.4928 and we round to 5.49.
Answer:
h = 11/9 or 1 2/9
Step-by-step explanation:
(-5/11)h+(7/9)=(2/9)
(-5/11)h=(2/9)-(7/9)
(-5/11)h=(-5/9)
h = (-5/9)(-11/5)
h = 11/9
or
h = 1 2/9
In the second case you have $4.59 per 20 ounces
Thus take 4.59 / 20 and you get $0.2295 per ounce or almost 23 cents per ounce
Hope it helps
