Answer:
x = 1, y = 2, z = 4
Step-by-step explanation:
(x + 4y – z = 5
2(3x – 2y + 2z = 7
)
6x - 4y + 4z = 14
7x + 3z = 19
3(2x – z= -2)
6x - 3z = -6
13x = 13
x = 1
6(1) - 3z = -6
-3z = -12
z = 4
(1) + 4y - 4 = 5
4y = 8
y = 2
Answer:
$516
Step-by-step explanation:
first you multiply 12 and 25 and you get 300
then you multiply 12 and 18 and you get 216
Then finally you add 216 and 300 together to get $516
The correct answer is: " 1/8 " .
__________________________________________________________
Note: "4/9" is close to "1/2" . Since "4/8 = 1/2" ; and since "4.5/9" = "1/2" .
"1/8" is a MUCH SMALLER value than "1/2" ;
and: "1/8" is a much smaller value than "4/9".
__________________________________________________________
Hence, " 1/8" is much closer to "0" than "4/9" .

The correct answer is: "1/8" .

Answer:
3. x-inter = there is not one
y-inter = -4
slope = 1/3
y= 1/3x - (-4)
5. x-inter = 2
y-inter = 2
slope = 1/-1
y= -1x + 2
Step-by-step explanation:
You divide 8644 by 8 which equals 1080.5, but since you can't have half of one person you approximate it to 1080 or 1081.
