Answer:
$37.85
Step-by-step explanation:
Here the price is $34.98 and there's an 8.2% tax on that. To obtain the after-tax amount due, multiply $34.98 by (1 + 0.082), or 1.082, obtaining:
1.082($34.98) = $37.85 (rounded to the nearest cent)
The vertex of the parabola is <span><span>(<span>2,1</span>)</span><span>(<span>2,1</span>)</span></span>
.
So, the axis of symmetry is the line <span><span>x=2</span><span>x=2</span></span>
.
because 4x+20y=-36,so ( 4x+20y)/2=2x+10y=-18
(2x+10y)-(2x+5y)=-18-18
5y=-36
then y=-7.2
because 2x=18-5y
so x=(18-5y)/2=(18-5*(-7.2))/2=27
Answer: 3
Step-by-step explanation: To solve for A we need to get it by itself by doing the inverse of mulitplication, which is, division. 27/9=3, so a=3.
