Answer:
4 inches
Step-by-step explanation:
it is given that
1/2" on the blueprint -----> 12 feet actual length
we can rearrange to say :
12 feet actual length ---> 1/2" on paper
or
1 foot actual length = (1/2)" ÷ 12 = 1/24" on paper
hence
96 feet actual length = 1/24 x 96 = 4 inches (answer)
Answer:
C. f⁻¹(x) = 3 - 5x
Step-by-step explanation:
To find the inverse of a function, switch x and y and solve for y.
f(x) = (3 - x)/5
Change f(x) to y.
y = (3 - x)/5
Switch x and y.
x = (3 - y)/5
Multiply both sides by 5.
5x = 3 - y
Subtract 3 from both sides.
5x - 3 = -y
Multiply both sides by -1.
-5x + 3 = y
Switch the sides.
y = -5x + 3
Change the equation.
y = 3 - 5x
Answer:
x = 4
Step-by-step explanation:
Given that DE is parallel to AC then DE divides the sides proportionally, so
= 
, substitute values
= 
( cross- multiply )
3x = 2(x + 2) ← distribute
3x = 2x + 4 ( subtract 2x from both sides )
x = 4
