The expression that could be used to determine the cost of a $50 video game after a 20 percent discount is:

$50(0.80)

$50(0.80) = $40 discounted amount

$50 * 20% = 10 discount value
$50 - 10 = $40 discounted amount

If you would like to know the expression that could be used to determine the cost of a $50 video game after a 20 percent discount, you can do this using the following steps:

$50 - 20% of $50 = $50 - 20% * $50 = $50 - 20/100 * $50 = $50 - 1/5 * $50 = $50 - 0.20 * $50 = $50 * 0.80 = $40

The correct result would be $50(0.80).

$\mathsf{-\dfrac{c}{2}+43-43=50-43}$

$\large\textsf{CANCEL out: 43 - 43 because that gives you 0}$

$\large\textsf{KEEP: 50 - 43 because it helps solve for the c-value}$

If you triple 4 and subtract 2 each day, how many days until you have zero

Gnom [1K]

<span>Triple 4 and subtract 2 each day
Find the number of days to be able to reach zero
1st day = 3(4) – 2
=> 12 - 2
=> 10
2nd day
=> 10 - 2
=> 8
3rd day
=> 8 – 2
=> 6
4th day
=> 6 – 2
=> 4
5th day
=> 4 – 2
=> 2
6th day
=> 2 – 2
=0

In 6th day, you’ll be able to get the amount of zero by subtracting 3(4) by 2.</span>

The slope of a line is 5, and you know it goes through the point (6, 2). Another point on the line goes through the y-coordinate

grigory [225]

Y = mx + b
slope(m) = 5
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 5(6) + b
2 = 30 + b
2 - 30 = b
-28 = b
so the equation for this line is : y = 5x - 28

y = 5x - 28.......when y = -3
-3 = 5x - 28
-3 + 28 = 5x
25 = 5x
25/5 = x
5 = x <==== ur x coordinate
