Answer:
w = - 16.06 or w = 2.06
Step-by-step explanation:
Given
w² + 14w - 33 = 0 ( add 33 to both sides )
w² + 14w = 33
To complete the square
add ( half the coefficient of the w- term )² to both sides
w² + 2(7)w + 49 = 33 + 49, that is
(w + 7)² = 82 ( take the square root of both sides )
w + 7 = ± ( subtract 7 from both sides )
w = - 7 ± , that is
w = - 7 - ≈ - 16.06 or w = - 7 + ≈ 2.06
Answer:
Hence, the input value that produces the same output for the functions represented by the tables is:
x=2
Step-by-step explanation:
We are given a function f(x) and g(x) as:
and
Clearly the function g(x) and f(x) are linear function.
We have to find such input value that gives the same output value for the function.
i.e. we have to find x such that:
g(x)=f(x)
i.e. -0.5x+2=2x-3
⇒ 2x+0.5x=2+3
⇒ 2.5x=5
⇒ x=5/2.5
⇒ x=2
Hence, the input value that produces the same output for the functions represented by the tables is:
x=2
Answer:
20days
Step-by-step explanation:
1 bag feed : 5/2 = 2.5 days
8 bags feed : 2.5*8 = 20 days
Okay, first we solve for the numerator:
7 + 4 = 11
Because the deminators are the same, the answer should be 11/15
