Answer:
(x, y) = (-10, -7)
Step-by-step explanation:
#1 Multiply the first equation by 7
#2 Then multiply the second equation by 5
1. 14x - 35y = 15
2. 10x - 35y = 55 (-
---------------------------
4x = -40
x = -10
Then go back to equation one and replace "x" with -10
2(-10) - 5y = 15
-20 - 5y = 15
-5y = 15 + 20
-5y = 35
5y = -35
y = -7
The answer is
(x, y) = (-10, -7)
Hope this helps!
Have a nice day!

It's the third choice. Since the symbol is not greater than or equal to -3 so it must got left..
Answer:
Step-by-step explanation:
<em>Let the angle be x</em>
Tan x = 
Where opposite = 48, Adjacent = 50
Tan x = 
Tan x = 0.96
x = 
x = 43.8 degrees
Answer:
The mean of Sample #2 is 8
The mean absolute deviation for Sample #2 is 4.08
Step-by-step explanation:
To find the mean for Sample #2, you find the sum of the values in the set and divide it by the number of elements in that set.
18+14+0+7+5+7+10+7+6+9+12+3+14+4+11+6+0+10+9+5+0+16+11+2+4 = 200
200 ÷ 25 = 8
To find the mean absolute deviation for Sample #2, you calculate how far away each data point is from the mean using positive distances. These are the absolute deviations. Afterward, you add those deviations together and divide the sum by the number of data points.
10+6+8+1+3+1+2+1+2+1+4+5+6+4+3+2+8+2+1+3+8+8+3+6+4 = 102
102 ÷ 25 = 4.08

Answer:
x=-2
Step-by-step explanation:
6x-5=-17
Add 5 to both sides of the equation.
6x=-12
Divide both sides by 6 to get x alone.
x=-2
