Answer:

y=x+2

Step-by-step explanation:

y=mx+b

m is slope

b is y intercept

it crosses the y intercept at (0,2) therefore b is 2

rise over run is 1 so slope is 1

fill in

y=1x+2

or y=x+2

you can fill in any (x,y) point into this

Carl ran around the track 3 more times than Daria and 2 fewer times than Erin. When they were done they added up the number of l
Paul [167]

Answer:

Total laps = 10d

Step-by-step explanation:

Let c = Carl's laps

d = Daria's laps

e = Erin's laps

c = 3d

c = e/2

c + d + e = totals laps

We can insert 3d in place of c in the third equation

3d + d + e = total laps

Also, e/2 equals 3d

e/2 = 3d

Multiply both sides by 2

(e/2 = 3d)2

e = 6d

Insert the new e

3d + d + 6d = 10d = totals laps

What is the length of side CD? (the answer is 48 but idk how to get there)
dedylja [7]

Answer:

Step-by-step explanation:

BD=\sqrt{10^2-2^2}\\ BD=\sqrt{100-4} \\BD=\sqrt{96}\\ BD=4\sqrt{6}

Similar triangles

tan(\alpha )=tan(\alpha )\\\\ \\\frac{BC}{BA} =\frac{BD}{AD} \\\\\frac{BC}{10} =\frac{4\sqrt{6} }{2}\\\\BC=2\sqrt{6} *10\\BC=20\sqrt{6}

Pythagorean theorem

CD=\sqrt{BC^2-BD^2} \\CD=\sqrt{(20\sqrt{6} )^2-(4\sqrt{6} )^2} \\CD=\sqrt{400(6)-16(6)} \\CD=\sqrt{2304} \\CD=48
