Answer:
28
Step-by-step explanation:
when x = 7,
Substituting value of x in the given equation,
x(x-3)
=> 7(7-3)
=> 7(4)
=> 28
Answer:
This function s a linear relationship because this function increases about a consistent slope. The equation is 2x+5, where 2 is the slope.
Step-by-step explanation:
Isolate "x" on one side of the algebraic equation by dividing the number that appears on the same side of the equation as part of "x."
Answer:
μ = 1.877
Step-by-step explanation:
Data provided in the question:
Number of data samples, n = 10
Data: 2.18, 2.03, 1.56, 1.09, 1.56 ,2.28 ,1.62 ,2.02 ,2.11 ,2.32
Now,
Mean is calculated using the formula as:
Mean, μ = 
or
Mean, μ = 
or
Mean , μ = 
or
Mean , μ = 1.877
Let the two numbers be x and y.
x + y = 86
+
x - y = 12
_________
2x + 0 = 98
__________
2x = 98
x = 98/2
x = 49
From x + y = 86
49 + y = 86
y = 86 - 49
y = 37
The numbers are 49 and 37.
