Hey! I can explain exactly how to do this. First off, we need to find slope to do slope intercept form, y = mx+b. To do this, we need two points, and use the formula y2-y1/x2-x1. Because I can't see the points clearly, I can give you an example. If we had (3,5) and (5,6), we would have 6-5/5-3, getting us 1/2 as our slope. Next, we need the y-intercept, or b. The way we find it is we see at which point does the like cross the y axis, the one that goes up and down. This point will always be (0, and then the y value) as there is no x value. Make sure to do this for all of these, and always write it in slope intercept. Message me if you need any more help! I'm here if you need me.
Tv=t
dvd=d
t+d=1257
t=2d
d=d
2d+d=1257
3d=1257
divide 3 from each side
d=419
t= 2 (419)
t=838

Create equivalent expression in the equation that all have equal bases, then solve n
Answer:
1)28.8%
2)28.8%
3)43.6%
Step-by-step explanation:
1))Probability of wining both = Probability that first contract is won* Probability that second contract is won = 0.4 * 0.72 = 0.288 = 28.8%
2)Probability of losing = 1 - Probability of winning
Probability that they will lose both contracts = Probability that first contract is lost * Probability that second contract is lost = (1 - 40/100) * (1 - 54/100) = 0.276 = 27.6%
3)Probability that any one is won = 1 - both contracts are won - both contracts are lost = 1 - 0.276 - 0.288 = 0.436 = 43.6%
$1380 is the price of the bike, because $276 multiplied by 5 is $1380
