Answer:
Y2-y1/x2-x1
=2-(-6)/2-(-2)
=8/4
=2
Step-by-step explanation:
Given two points of a line to find the slope we use the formula; y2-y1/x2-x1 Hence the answer above.
Answer:
x ≥ 1/2
Step-by-step explanation:
6x + 21 ≥ 24
6x ≥ 3
x ≥ 1/2
check: (1/2 x 6) + 21 = 24
Answer:
<em>The price at which A bought the item is $1200.</em>
Step-by-step explanation:
Suppose, the price at which A bought the item is
dollar.
A sells the item to B at 15% profit. That means, the selling price to B
dollar.
B sells the same item to C at 20% profit. That means, the selling price to C
dollar.
Given that, C pays $1656 for the item. So, the equation will be.......

So, the price at which A bought the item is $1200.
