Answer:
4x + y = k
Step-by-step explanation:
=> 4y = x + 8
=> x - 4y = -8
Slope = 1/4
The other line's slope = -4
4x + y = k is the answer.
You would get back $1
$9.99-$1.50= $8.49 <--- 15% off
$8.49x.06= .51 cents <--- Taxes
$8.49+.51<--cents= $9 <--- Total cost of the T-shirt
6/9 and 12/21
i think this is the answer your looking for
B²-4ac?
<span>5x²+7x-6 = 0 </span>
<span>the form is ax²+bx+c = 0 </span>
<span>a=5, b=7, c=-6 </span>
<span>The discriminant D = b²-4ac </span>
<span>= 7² - 4(5)(-6) = 49 + 120 </span>
<span>= 169 </span>
