The answer is triangle number 2
Answer:
x=12
Step-by-step explanation:
height of tree)/(shadow length of tree) = (height of pole)/(shadow length of pole)
x/26 = 6/13
13x = 26*6
13x = 156
x = 156/13
x = 12

Answer:
Step-by-step explanation:
a.
y=0.75x
y-y1=(y2-y1)/(x2-x1)×(x-x1)
y-3=(6-3)/(8-4) (x-4)
y-3=3/4(x-4)
y-3=3/4 x-3
y=3/4 x-3+3
y=3/4 x
if y=f(x)
f(x)=0.75x
c.
f(12)=0.75×12=9$
The slope will be the same, so we know the equation will be y=-2x+b. But there is a different b.
For x=4, y will be 1 because the point (4,1) is given.
So 1=-2*4 + b => b = 9
So the equation of our parallel line is y=-2x+9
If we subtract 1 from both sides, we get y-1 = -2x + 8
Then factor out -2 on the right hand side: y-1 = -2(x - 4)
That's answer A!
