Yes , taking root on both sides we have y = √(4-x^2) so y is dependant on x and x only..so y is a function of x .

Answer:

$\boxed{\stackrel{\Large\frown}{PQS}\:= 222°}$

Explanation:

Since $\overline{PR}$ is a diameter, arc $\stackrel{\Large\frown}{PQR}\:= 180°.$

Given that $\angle{SUR} = 42°$ is a subtended central angle by two diameters,

$\stackrel{\large\frown}{RS} \:= 42°$ .

Using the rule of arcs, $\stackrel{\Large\frown}{PQR} + \stackrel{\large\frown}{RS} \: = \: \stackrel{\Large\frown}{PQS}$ →

$180° + \: 42° = \: \stackrel{\Large\frown}{PQS}$

$222° = \: \stackrel{\Large\frown}{PQS}$

$\stackrel{\Large\frown}{PQS} \: = \: 222°$

One number is 9 more than twice another. If their difference is 22, what is the larger number?

mafiozo [28]

Let, the numbers are: x, y
So, Equations will be: x - y = 22
x = 2y + 9

Substitute the value of x in first equation,
2y + 9 - y = 22
y = 22 - 9
y = 13

x - 13 = 22
x = 22 + 13 = 35

In short, Larger number would be 35

Hope this helps!
