Hey there, if you want to know the tax of 40 dollars. The answer is going too be 43.20. Or if you want to know just the tax its going to be 3.20.
The way i did this was to multiply 40 times 8 since each tax is 8 cents.
Answer:
Step-by-step explanation:
the perimeter is : p = 2(x+y)..... x : width y : length
you have the system ; 2(x+y) = 252.......(1)
x = (2/7) y ...........(2)
y > x ....(3)
Substitute x = (2/7) y into (1) and simplifiy and solve for y :
(2/7) y + y = 126
(2y+7y)/7 = 126
9y = 882
y = 98 m ( the length )
Answer:
Step-by-step explanation:
y=(x-a)²+h
vertex (a,h)
axis of symmetry x-a=0 or x=a
x-intercepts (none)
y-intercepts (none)
graph upper parabola (don't understand what it requires )
Domain (-∞,∞)
Range [0,∞)
<span>x(x+2)+x(x-3)
=x^2 + 2x + x^2 - 3x
= 3x^2 - x</span>
