Answer:
:)
Step-by-step explanation:
There are several ways to do this. The first, which I personally think is the quickest way without having to do too much math or rearranging the equation is to simply pick random points for x and solve for y.
For instance, you might try -2 for x.
- ( - 2)^2 - 4 ( - 2) - 3
= - 4 + 8 - 3
= 1
So one of your points would be (-2, 1)
Then you might choose, say, -3 for x. And after that, -1 for x. If you want to graph even more points after those (the more points, the more accurate your graph), choose -4 and 0 for x. Simply put it into the equation and find y. Then graph.
Step-by-step explanation:
here's the answer to your question
10 weeks is the number of weeks they have been saving their money.
Duane = $5 every two weeks
Mick = $2 every week.
Get the value of Duane's weekly contribution = $5 / 2 = $2.5
Duane's share + Mick's share = $45
$2.5x + $2.0x = $45 ===>> equation can also be x(2.5 + 2) = 45
$4.5x = $45
$4.5x / $4.5 = $45 / $4.5
x = 10 weeks.
To check:
$2.5(10) + $2(10) = $45
$25 + $20 = $45
