Answer:
48%
Step-by-step explanation:
let's say the initial price of an item is $100
if you take 40% off then you pay only $60
now if you take 20% off 60 you pay $48
$48 is 48% of 100
Answer:
linear monomial
Step-by-step explanation:
Y= mx +b ; x is the slope and y is the y-intercept.
So in this case, our equation will be y= 3x + 19 :)
710/70 = 10.14, so round up to 11. The answer is C.

since -x^2+x+19=y
<span>
</span>
x=-x^2+x+19+80
<span>
</span>
x=-x^2+x+99
<span>
</span>
0=-x^2+99
<span>
</span>
x^2=99
x=3√11
x=y+80
3√11=y+80
minus 80 both sides
-80+3√11=y
x=3√11
y=-80+3√11
solution
(x,y)
(3√11,-80+3√11)
