Answer:
Step-by-step explanation:
The ration of weight of nickel, zinc, and copper in an alloy is 4:1:2
The weight of alloy can be written as
4x + x + 2x = 35 Kg
7 x = 35 Kg
X = 35 Kg/7
X = 5kg
The weight of nickel the alloy = 4 x 5 = 20 Kg
The weight of zinc in the alloy= 1 x 5 = 5kg
The weight of copper in the alloy = 2 x 5 = 10 kg

Answer:
The function's input = x = -20
Step-by-step explanation:
Given the function
y = -75 - 5x
Given that the output = y = 25
substituting the value y=25 and solve to find the input 'x'
25 = -75 - 5x
5x = -75-25
5x = -100
Divide bothe side by 5
x = -20
Thus, the function's input = x = -20
