0.1, then 12% and then 1/8
Answer:
x^2-72=12x
Step-by-step explanation:
(xy=x times y just fyi)
bought bike for 368.9
this was including sales tax of 8.5%
(percent means part out of 100 so 8.5%=8.5/100=0.85/10= 0.085/1 1=0.085)
so paid=price+tax
paid=368.9
price=p
tax=p times 8.5%=0.085
368.9=p+p times 0.085
368.9=p+0.085p
or
p+0.085p=368.9
the answer is C
X-intercept: y = 0
y-intercept: x = 0
3x + 4y = 0
x-intercept: subtitute y = 0
3x + 4 · 0 = 0
3x = 0
x = 0 → (0; 0)
y-intercept: subtitute x = 0
3 · 0 + 4y = 0
4y = 0
y = 0 → (0; 0)
