Answer:
126°
Step-by-step explanation:
(2x +18)° = (3x)°
2x + 18 = 3x
18 = 3x - 2x
18 = x
therefore, (3x)° = (3*18)°= (54)°
![m\angle SRW + (3x)\degree = 180\degree \\m\angle SRW + 54\degree = 180\degree \\m\angle SRW = 180\degree - 54\degree \\\huge\red{\boxed{m\angle SRW = 126\degree}}](https://tex.z-dn.net/?f=m%5Cangle%20SRW%20%2B%20%283x%29%5Cdegree%20%3D%20180%5Cdegree%20%5C%5C%3C%2Fp%3E%3Cp%3Em%5Cangle%20SRW%20%2B%2054%5Cdegree%20%20%3D%20180%5Cdegree%20%5C%5C%3C%2Fp%3E%3Cp%3Em%5Cangle%20SRW%20%3D%20180%5Cdegree%20%20-%2054%5Cdegree%20%20%5C%5C%3C%2Fp%3E%3Cp%3E%5Chuge%5Cred%7B%5Cboxed%7Bm%5Cangle%20SRW%20%3D%20126%5Cdegree%7D%7D)
Answer:
n ≥ 1/4
Step-by-step explanation:
I wish I could add a picture, but I can't, so you'll have to graph it by yourself.
Answer:
A (9, 3)
Step-by-step explanation:
First the point is rotated 90° counterclockwise about the origin. To do that transformation: (x, y) → (-y, x).
So S(-3, -5) becomes S'(5, -3).
Next, the point is translated +4 units in the x direction and +6 units in the y direction.
So S'(5, -3) becomes S"(9, 3).
Answer:
L2: y-0 = 5/2(x-5)
y = 5/2x-25/2
Step-by-step explanation:
Parallel lines have same slopes.
Line 1, L1: 5x-2y=20 is in standard form Ax+By=C therefore slope m1= -A/B = -5/-2 = 5/2 or you can solve it for y so you will have the equation in slope-intercept form.
5x-2y = 20
-2y = -5x+20
y = (-5/-2)x+20/(-2)
y = (5/2)x-10 hence m1=5/2 and y-intercept is -10
Line 2 , L2: y-y1 = m (x-x1), m=m2=m1=5/2
Point p(5,0) or p(x1,y1) therefore x1=5 , y1=0 and m=5/2
L2: y-0 = 5/2(x-5)
y = 5/2x-25/2
