Answer:
$1,220
Step-by-step explanation:
multiply 30 times 19 and add 650 to get the total
A(b-c)=d
We are trying to leave c on one side, so we have to divide by a on both sides first to get
b-c=d/a
now we can subtract by b on both sides to get
-c=d/a-b
now multiply both sides by -1 to get
<span>c=-d/a+b</span>
Answer:
3rd option
Step-by-step explanation:
substitute x = f(x) into g(x)
g(f(x))
= g(x² + 2)
= 4(x² + 2) - 1
= 4x² + 8 - 1
= 4x² + 7
Answer:
(D) The intersection of two half planes.
Step-by-step explanation:
In order to solve the two order inequality, the two equations to be solved divides the cartesian plane into two half planes.
The intersection of the two inequalities gives the set of the points that satisfies both the inequalities. Thus, the solution of the two order inequality can be obtained by the intersection of the two half planes.
