4x-4y+4z=8
9x+3y+z=6
16x+4y+z=2
9514 1404 393
Answer:
(x, y, z) = (-1, 3, 6)
Step-by-step explanation:
The augmented matrix for the system is ...
[tex]\left[\begin{array}{ccc|c}4&-4&4&8\\9&3&1&6\\16&4&1&2\end{array}\right][/tex]
Your graphing or scientific calculator can tell you the solution to this system is ...
(x, y, z) = (-1, 3, 6)
__
If you want to solve this by hand, it can work well to divide the first equation by 4 to get ...
x -y +z = 2
This can be subtracted from the other two equations to eliminate z.
(9x +3y +z) -(x -y +z) = (6) -(2) ⇒ 8x +4y = 4
(16x +4y +z) -(x -y +z) = (2) -(2) ⇒ 15x +5y = 0
These two equations can be reduced to standard form:
2x +y = 13x +y = 0Subtracting the first equation from the second, we have ...
(3x +y) -(2x +y) = (0) -(1) ⇒ x = -1
Substituting into the first gives y:
2(-1) +y = 1
y = 3 . . . . . . . add 2
Then we can find z from the reduced first equation above:
z = 2 -x +y = 2 -(-1) +3 = 6
Then the solution is (x, y, z) = (-1, 3, 6).
Which of the following is not the equation of the graphed line

Ted has a part-time job.
He is paid £7.90 per hour.
Last week he worked for 15/2 hours.
Work out Ted's total pay for last week.
Answer:
The answer is 122.45
Step-by-step explanation:
So basically we know that he worked 15 and 1/2 hours
He gets paid £7.90 for every hour he works
7.90 × 15 = 118.5
Then you do half of £7.90 which is £3.95 because he worked 1/2 hours half of 60 minutes is 30 minutes that why you half £7.90.
You add 118.5 + 3.95 = £122.45
and that your answer
Sun estimated the quotient of -23.514 and -3.98 by rounding each to the nearest integer. Which equation shows the correct estimation?
-23.514÷-3.98
O -24÷-4=6
O -24÷4=-6
O 24÷3=8
O 24÷-3=-8
Answer:
A
Step-by-step explanation:
because if you are rounding to the nearest integer that means that -23.514 would be -24 and -3.98 would be -4 and negative divided by a negative is a positive

Which direction will the box move in the diagram below?
A.It will move to the left.
B.It will move to the right.
C.It will not move.
D.It will move up.
Answer:
B.it will move to the right.
Explanation:
We have 5 newtons of force pushing to the right, and 3 newtons of force pushing to the left. We can place the positive direction on the right hand side and the negative direction on the left.
This means we can think of "3 newtons of force to the left" as the integer -3
That way we can then add 5 to -3 getting 5+(-3) = 2. The result is positive, meaning the net force is pushing to the right. Specifically, 2 newtons of force are pushing to the right.
It's like saying there are 5 people pushing to the right and 3 pushing to the left. From each side, 3 people will pair up and they'll cancel each other out. The 2 extra people pushing right will ultimately win out.
given the segments as shown for what value of x is the figure a rectangle
A. 5.
B. 7
C. 3
D. 9
Answer:
[tex]x = 7[/tex]
Step-by-step explanation:
Required
Determine the value of x
The diagonals of a rectangle are equal.
So:
[tex]x + 5 + 2x -2 = 3x -9+4x - 16[/tex]
[tex]x + 2x + 5 - 2 = 3x +4x - 9 - 16[/tex]
[tex]3x + 3 = 7x -25[/tex]
Collect Like terms
[tex]3x-7x=-25-3[/tex]
[tex]-4x=-28[/tex]
[tex]x = \frac{-28}{-4}[/tex]
[tex]x = 7[/tex]
Please answer this HELLLPPPP!!!!!
Answer:
x = 10
Step-by-step explanation:
Diagonals of a rhombus bisect each other at a 90° angle, but most importantly (for this problem), they bisect the opposite angles of the rhombus equally.
This means that the two angles, given by the expressions (6x + 12) and (8x - 8), are equal to each other.
Set them equal to each other in an equation and solve for x.
6x + 12 = 8x - 8Subtract 6x from both sides.
12 = 2x - 8Add 8 to both sides.
20 = 2xDivide both sides by 2.
x = 10The value of 10 for x will make the given parallelogram a rhombus.

if a number, n, divided by 8 equals 2.5, what is n?
Answer:
n is 20
Step-by-step explanation:
If n/8=2.5, then you can just do 8*2.5 to find n. 2.5*8=20
Answer:
n=20 because if you multiple 2.5 and 8 you will get 20 so if you divide 20 and 8 then you get 2.5

Answer:
a=3,b=1
Step-by-step explanation:
In a parallelogram opposite sides are equal/congruent.
Using this, we know that 3a-4=a+2 and b+1=2b
1st equation:
3a-4=a+2
-a -a
2a-4=2
+4 +4
2a=6
a=3
2nd equation:
b+1=2b
-b -b
b=1
a=3, b=1
