Answer:
OPTION C: 105 ft.
Step-by-step explanation:
Note that the width of the building in the map is 3 ft.
The width of the actual building is 45 ft.
That means, the actual building is 15 times more than the map, since, .
Therefore, the height of the actual building would be 7 X 15 = 105 ft.
Hence, the height of the actual building is 105 ft. which is OPTION C.
Answer:
y = 3x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line
m = =
=
= 3
the line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = 3x + 3 ← equation of line
