Answer:
15
Step-by-step explanation:
A={6,11,16,...,76}
a=6,d=11-6=5
so the cardinal number is 15
-x + 2y = 6 then x = 2y - 6
6y = x +18 then x = 6y - 18
-----------------------substract
0 = -4y + 12
4y = 12
y = 3
-x + 2y = 6
-x + 2(3) = 6
-x = 6 - 6
x = 0
answer: x = 0 (second choice)
Answer:
x=2
Step-by-step explanation:
x6−7=5
x6=7+5
x6=12|:6
x=2
Answer:
It is <em>a</em> solution, one of an infinite number of solutions.
Step-by-step explanation:
You can check to see if the given point is in the solution set:
4(-4) +5(4) = -16 +20 = 4 > -6 . . . . yes
-2(-4) +7(4) = 8 +28 = 36 > 20 . . . yes
The offered point satisfies both inequalities, so is in the solution set. It is not <em>the</em> solution, but is one of an infinite number of solutions.
