The height would be 3 feet because it would be just tall enough to be waist level
RS+ST=RT
RS=7y-4
ST=y+5 using RS and RT in the first equation gives you:
7y-4+y+5=RT combine like terms on left side
8y+1=RT, and we are told that RT=28 so:
8y+1=28 subtract 1 from both sides
8y=27 divide both sides by 8
y=27/8
(RS=19 5/8, ST=8 3/8, RT=28)
P(e)=number of evens/number of numbers :)
P(e)=3/6=1/2
First you find your slope which is rise/run, so, 1/3, and a line this way (/) is positive, so it's positive 1/3.
Then you see where it crosses the y axis: -1.
Plug that into y=mx+b giving you y=1/3x-1.
Your answer is D.
Answer:
x = 5
y = -1.25
Step-by-step explanation:
3x+4y=10
3x-4y=20
----------------
6x=30
x=5
3(5)-4y=20
15-4y=20
-4y=5
y=-1.25
