Answer:
(x,y,z)=( -2, -1 ,5)
Step-by-step explanation:
9x+2y-27z=-155 (1)
-11x-y+37z=208 (2)
19x+6y-52z=-304 (3)
(1) *3 ;(2) *6 ;(3)*1, you have
27x+6y-81z=-465 (1)
-66x-6y+222z=1248 (2)
19z+6y-52z=-304 (3)
(1) +(2), you have
-39x+141z= 783 (4)
(4) /3, you have
-13x +47z=261 (4)
(2) +(3), you have
-47x+170z=944 (5)
From ( 4) and (5), you have equations
-13x +47z=261 (4)
-47x+170z=944 (5)
(4)*(-47); (5)*13, you have
611x-2209z=-12,267 (4)
-611x+2210z=12,272 (5)
(4)+(5), you have
z=5
Replace z=5 in (4), you have
611x- 2209*5=-12,267
611x- 11,045 =-12,267
611x=-1222
x= -2
Replace x=-2, z=5 in (1) , you have
9*(-2) +2y -27*5=-155
-18+2y-135=-155
-18+2y=-20
2y=-2
y=-1
Result (x,y,z)=( -2, -1 ,5)

Step-by-step explanation:
you jus add all the numbers up.
Using translation concepts, it is found that:
- The parent function y =
is decreasing across it's domain because it's base, b, is such that 0 < |b| < 1.
- The function f shifts the parent function 8 units up.
- The function f shifts the parent function 5 units right.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The parent function is:
It has a base with absolute value between 0 and 1, hence it is decreasing.
The changes to the function are given as follows:
- y -> y + 8, hence the function was shifted 8 units up.
- x -> x - 5, hence the function was shifted 5 units right.

Answer:
The nearest 100,000 of 89,678 would be 100,000.
Step-by-step explanation:
For me to simply put this, ignore the digits behind the commas.
You'll have 89, and imagine you have to get it to the nearest 100.
So when rounding / estimating, if the digit you're talking about is above 5, you round up. If it is below 5, you round down.
Since you have 89, you'd round up to a 100 because 89 is over 50.
Therefore you'd have 100,000 if you're rounding 89,678 to the nearest hundred thousand.
