Answer:
x=11.5
Step-by-step explanation:
2x+8=-15
x=-23/2
x=-11.5
Answer:
1)· 5x + 2y = 9. First we solve for y. 2y= 9 -5x. y=(9-5x)/2. Now that we have the value of y. We substitute on the original equation and resolve. 5x + 2y = 95x + 2y = 9 5x + 2(9-5x)/2 = 9 5x + 9 - 5x = 9 9 = 9
That would be x = 1
Now substitute and resolve to find y.
5(1) + 2y = 9
5 + 2y = 9
2y = 4
y = 2
So our answer x=1 and y = 2. (1,2)
Proof :
5(1) + 2(2) = 9
5+ 4 = 9
9 = 9

Answer:
i√17 ≈ 4.123106i
Step-by-step explanation:
The square root of a negative number is "i" times the square root of its absolute value. It is an imaginary number.
_____
i is generally the symbol used for √(-1). In some fields, such as electrical engineering, where i has a different meaning, the symbol j may be used instead.
2 (6 x+6)= ?
12 x+ 12=
12 x= -12
x= -1
So first you take what is outside the "( )" and you multiply it with what's in the "( )" so that gave us 12 because 2*6= 12.
