Y^2-5=31 add 5 to both sides
y^2=36 take the square root of both sides..
y=±√36
y=±6
y=-6 and 6 so B and D is the answer.
Actual length of the pole and the length of the shadow cast by the pole follow the proportional relationship.
Following this rule, 20 feet tall flagpole will cast 3.33 feet shadow.
If the length of the shadow = x feet
Proportional relationship will be defined by the expression,


feet
Therefore, length of the shadow cast by flagpole will be 3.33 feet.

Answer: y = -x + 2
Step-by-step explanation:
If you are familliar with the point-slope form this is very helpful
Point-slope:

Plug in our values of
to get:

Simplify


Black - 10/35 (2/7)
White - 20/35 (4/7)
Grey - 5/35 (1/7)
7 and 2 cannot be the lengths as on a triangle they're two equal side so two 3s or two 5s
