Answer: In the equations that you have given, we have a dependent system.
2x + y = 8 (I assumed that you meant to type y instead of 7)
6x + 3y = 24
To use Cramer's Rule, we have to take the determinant of 3 different matrices written in the problem. Taking the determinant of the coefficient matrix produces a zero.
2 1 This is the coefficient matrix.
6 3
6 - 6 = 0
Since this is 0, the rest of the work will be undefined meaning the systems are dependent (or they are the versions of the same equation).
Answer:
-3
Step-by-step explanation:
2^2 = 4
4 + (-3) = 1
4*2 = 8
8 * -1 = -8
-8 / 2 = -4
1 + -4 = -3
Answer:
Step-by-step explanation:
y=(x+5)2−1
Use the vertex form,
y=a(x−h)2+k, to determine the values of a, h, and .a=1h=−5k=−1Find the vertex(h,k(−5,−1)
Given equation : n(17+x)=34x−r.
We need to solve it for x.
Distributing n over (17+x) on left side, we get
17n + nx = 34x - r.
Adding r on both sides, we get
17n+r + nx = 34x - r+r.
17n + r + nx = 34x.
Subtracting nx from both sides, we get
17n + r + nx-nx = 34x-nx
17n + r = 34x -nx.
Factoring out gcf x on right side, we get
17x + r = x(34-n).
Dividing both sides by (34-n), we get
<h3>Therefore, final answer is
</h3>
Answer:
The annual federal tax deduction is $2705.04 .
Step-by-step explanation:
As given deduction in a week
Federal Tax $52.02
As there are 52 weeks in a week.
Thus
Annual Federal Tax deduction = Total number of weeks in a year × Federal Tax deduction in week
= 52 × 52.02
= $ 2705.04
Therefore the annual federal tax deduction is $2705.04 .
