Answer:
a) A U B = {21,23,24,25,27,29,30,31 }
b) A n C = {24,30}
Step-by-step explanation:
A {21,24,27,30}
B {21,23,25,27,29,31}
C {20,22,24,26,28,30,32}
a) A U B = {21,23,24,25,27,29,30,31 }
b) A n C = {24,30}
Answer:
y = - 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x - 1 ← is in slope- intercept form
with slope m = - 2
Parallel lines have equal slopes , then
y = - 2x + c ← is the partial equation
To find c substitute (- 3, 2 ) into the partial equation
2 = 6 + c ⇒ c = 2 - 6 = - 4
y = - 2x - 4 ← equation of parallel line
