Answer:
-11.5
Step-by-step explanation:
4(x-2/3)=-18
4x-8/3=-18
4x-8=-18×3
4x-8=-54
4x=-54+8
4x=-46
x=-46/4
x=-11.5
(-5, 7) - Quadrant II
(8 1/2, -4) - Quadrant IV
(0,5) - y axis
Step-by-step explanation:
<span>7x + 2y = 48
</span><span>7x + 2(3) = 48
7x + 6 = 48
7x = 42
x = 6
answer </span><span>when y = 3, x = 6</span>
The correct answer would be C :^)
Rational numbers are closed under addition ,multiplication but not closed under division
Rational number
Closure property
assume two rational numbers say x and y. the results of addition and multiplication operations give a rational number we can say that rational number are closed under addition and multiplication . For example
rational number are not closed under division as 1 and 0 are rational number but 1/0 is not defined but it is closed under addition and multiplication
that is 1+0 = 1 closed under addition
1*0 =0 closed under multiplication
but 1/0 is not defined so it is not closed under division
Hence Rational numbers are closed under addition ,multiplication but not closed under division
