Answer:

Step-by-step explanation:

they want us to find the equation in slope intercept form

which is y= mx + b

where m = slope and b = y intercept

the slope is change in y over change in x

as y goes up 1 x goes up 1 so the slope is 1 or m=1

the y intercept is at point (0,1)

so the y intercept is 1

now we add it all together and get that the equation Is

y=x+1

A raft and a motorboat simultaneously leave from the same point and move down the river. After 2 hours the motorboat turns aroun

lesya692 [45]

Answer:

2 hours

Step-by-step explanation:

Let x mph be the speed of motorboat in still water and y mph be the speed of current.

A raft and a motorboat simultaneously leave from the same point and move down the river, then speeds down the river are:

motorboat = x + y mph

raft = y mph

In two hours they will cover:

motorboat = 2(x+y) miles

raft = 2y miles

After 2 hours the motorboat turns around and starts moving towards the raft (against the current), so its speed is now x - y mph.

Let t be the time they move towards each other. In t hours, they cover

motorboat = t(x - y) miles

raft = ty miles

The distance from the starting point to the turning point is the same as the sum of the distances the raft covers and the motorboat covers after turning around, so

$2(x+y)=2y+t(x-y)+ty \\ \\2x+2y=2y+tx-ty+ty\\ \\2x=tx\\ \\t=2\ hours$

Use the distance formula to find the distance, to the nearest tenth, from S(5,-4) to W(-3,7)

natali 33 [55]

Answer:

Distance (d) =13.6

Step-by-step explanation:

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\(5,-4)=(x_1,y_1)\\(-3,7)=(x_2,y_2)\\\\d=\sqrt{\left(-3-5\right)^2+\left(7-\left(-4\right)\right)^2}\\\\d=\sqrt{(-3-5)^2+(7+4)^2}\\\\d=\sqrt{(-8)^2+(11)^2}\\\\d=\sqrt{64+121}\\\\d=\sqrt{185} \\\\d = 13.60147\dots \\\\\\d =13.6$

The equation of a line is −2x 5y=−20−2x 5y=−20. what is the x-intercept of the line? enter your answer in the box.

kotegsom [21]

The criteria to find out the x-intercept of the line is we find out the result when
y = 0

- 2x + 5y = -20
- 2x + 0 = -20

x = -20 / -2
x = 10

hope this helps
