Answer:
Step-by-step explanation:
we know that
The measurement of the external angle is the semi-difference of the arcs which comprises
In this problem
m∠RPS=
------> external angle
so
m∠RPS=
we have
m∠RPS=
substitute the values
Solve for arc RS
Answer:
a) 3x - 6x^2y + 2xy - 2x
b) 4x^2 <u>- 3y </u>+ 2x <u>+ 7y</u>
Step-by-step explanation:
Like terms is when the terms are the same.
For example, 3x and -2x would be like terms (both have x).
Not like terms would be 4x^2 and +2x (one is just an x and the other is x^2).
Answer:
40x^6

Answer:
The equation is 2y = x-3
Step-by-step explanation:
Equation of WX is;
2x + y = -5
Can be written as;
y = -5 -2x
compare it with standard form
y = mx + c
where m is slope and c is intercept.
Slope of the line is thus -2
The second line is perpendicular to WX
this means that the product of their slopes is -1
Mathematically;
-2 * slope of second line = -1
Slope of second line is -1/-2 = 1/2
Now we use the point slope form to get the equation of that second line
Mathematically;
y-y1 = m(x-x1)
y-(-2) = 1/2(x-(-1))
y + 2 = 1/2(x + 1)
2(y + 2) = x + 1
2y + 4 = x + 1
2y = x + 1-4
2y = x-3
