Im pretty sure the answer is D, because if i used the right formula,
you should get this in the formula
a 2 subtracting a negative 6 makes it a positive, meaning your just adding 6 plus2, to get 8
If the slope if is undefined, then the line is vertical.
The equation of a vertical line: x = a (a - any real number).
The line passes through the point (-3, 0) → x = -3 and y = 0.
Therefore we have x = -3.
The general form of a line: Ax + By + C = 0.
x = -3 <em>add 3 to both sides</em>
<h3>x + 3 = 0</h3>
Answer:
10.5
Step-by-step explanation:
2,2,6,15,38,39
6 and 15 are in the middle so add them
21 then divide by 2
10.5
Answer:
59.38 ft
Step-by-step explanation:
The person and his shadow form a triangle. The tree and its shadow also form a triangle. The triangles are similar triangles, so the lengths of corresponding sides are proportional.
Let the unknown tree height be h.
(person's height)/(person's shadow) = (tree height)/(tree's shadow)
(75 in.)/(48 in.) = h/(38 ft)
(25)/(16) = h/(38 ft)
16h = 25 * 38 ft
16h = 950 ft
h = 59.375 ft
h = 59.38 ft
A2+B2=C2
12(2)+B(2)=27.1(2)
24+B=54.2
-24 -24
——————
B=30.2
Answer is 30.2
I hope this helps
