I would use elimination
2x+3y = 7
2x-y = -5
Subtract those equations
4y = 12
Y = 3
Now plug in 3 for any y value
2x - 3 = -5
2x = -2
X = -1, y = 3
Answer: Thanks
Step-by-step explanation:
Hello,
y=-g/2 t²+25 t is the trajectoire with g=9.81 m/s²
y=-g/2 (t²-25*2/g t)
==>y=-g/2(t²-2*25/g t +25²/g²)+25²/g² * g/2
==>y=-g/2(t-25/g)²+25²/(2g)
==> h=25²/(2g)=625/(2*9.81*3.28084)=9,709479... feet
(for 1m=3.28084 feet)
Answer:

Answer:
21 inches answer F
Step-by-step explanation:
x+6+2x-2+2x+6=85
5x+10=85
5x=75
x=15
shortest is x+6
15+6
21.
Hope this helps plz hit the crown :D
