Answer:
x=3, z=-1, y=6
Step-by-step explanation:
you need to make the coefficients of each variable equal to each other then subtract 2 equations.
this one: multiply -4 in 1st
4x+4y+4z=32
-4x+4y+5z=7
_____________
8x+0-z=25
we have 2 equations with 2 variables now
2x+2z=4
8x-z=25
Answer:

Step-by-step explanation:
Given

Required
Determine the period
A sine function is represented as:

Where

By comparing:
and 

So:

So, we have:



Hence, the period of the function is 
Answer:
x = 13
Step-by-step explanation:
1765
x = 100 (9) + (7) 50 + (19) 20 + (7) 10 - 1765
x = 900 + 350 + 380 + 70 - 1765
x = 1700 - 1765
x = -65
65/5 = 13
x = 13
Given:
The compound inequality is:

To find:
The integer solutions that satisfy the given inequality.
Solution:
We have,

Subtracting 5 from each side, we get


All the real numbers between -3 and 2 are in the solution set but -3 and 2 are not included in the solution set.
The integers between -3 and 2 are -2, -1, 0, 1.
Therefore, the integer solution of the given inequality are -2, -1, 0, 1. The answer as an inequality is
.
