Answer:
Step-by-step explanation:
use substitution and solve this 8x+4(-2x+3)=12
with the 4 distributed its
8x-8x+12=12
then you can cancel out the 8x and -8x and switch the 12 over into a -12 canceling out the 12s making it x=0
Answer:
Step-by-step explanation:
w^3 + 4w^2 + 5w - 12
16r^2+ 2r -4r
16r^2 - 2r
2r ( 8r -1)
Y=mx+b
m=slope
paralell ines have same slope
y=2/3x-6
slope is 2/3
the equation of aline that passes through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
(3,14) and slope is 2/3
y-14=2/3(x-3)
y-14=2/3x-2
y=2/3x+12
58 plus tip of .20
so
58 times 0.2 = 11.6 is the tip
now we add tax (Presuming we son't tax the tip)
58 times 0.07 = 4.06 the tax
so its
58 + 11.6 + 4.06 = $73.66 total cost
