What is the value of x in the solution of the system of equations 3x + 2y = 12 and 5x – 2y = 42
1 answer:
Answer:
x = 27/4
Step-by-step explanation:
3x + 2y = 12 and 5x – 2y = 42
Add the two equations together to eliminate y
3x + 2y = 12
5x – 2y = 42
-----------------------
8x = 54
Divide each side by 8
8x /8 = 54/8
x = 27/4

The equation of a circle:
(h, k) - center
r - radius
Look at the picture:
center: (4, -2) → h = 4, k = -2
radius: r= 5
Substitute:
Answer:
Part A: <em>D,E</em>
Part B:
m°= <em>90°</em>
x°= <em>70°</em>
y°= <em>70°0</em>
z°= <em>110°</em>
