Answer:
30
Step-by-step explanation:
y/x = 30/(x + 10)
(y + 12)/x = 54/(x + 10)
y/x + 12/x = 54/(x + 10)
30/(x + 10) + 12/x = 54/(x + 10)
30x + 12(x + 10) = 54x
30x + 12x + 120 = 54x
120 = 12x
x = 10
EG = x + x + 10
EG = 10 + 10 + 10
EG = 30

Answer:
Slope = -1.71
Intercept = 22.05
Step-by-step explanation:
Equation of a line usually takes the general form :
ŷ = mx + c
Where :
m = slope or gradient
c = intercept
Inputting the data into a linear regression calculator ;
The output is : ŷ = -1.70872X + 22.04985
Comparing the output to the general formula;
The slope (m):
m = -1.70872 = -1.71(2 decimal places).
The intercept (c):
c = 22.04985 = 22.05(2 decimal places).
Answer:
12.5
Step-by-step explanation:
the radius of a circle is half of the diameter
Answer:
The period is smaller than π/2 so the only possible answer would be 2π/5
Frequency is the amount of cycles it completes in 2π, so it's 5
