The drawing of a building shown below has a scale of 1 inch to 30 feet. what is the actual height, in feet, of the building? the numbers are 1.25in and the other one is 0.75in.

Solution:

Given that,

The drawing of a building shown below has a scale of 1 inch to 30 feet

1 inch = 30 feet

The drawing of the building of this problem has the height of 1.25 inches and base of 0.75 inches

Thus actual height is given as:

height = 1.25 inches

The actual base is given as:

base = 0.75 inches

Thus actual base is 22.5 feet

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

you can't solve x because it is 2 linear equation and you only have one equation
