Answer:
option A. |c| is the answer.
because sqrt of any number is always positive. that's why we add the modulas symbol around the interger.
You are trying to solve for y (get y by itself)
9y + 10 = -8 Subtract 10 on both sides
9y + 10 - 10 = -8 - 10
9y = -18 Divide 9 on both sides
y = -2
Answer:
(23/27, 11/9)
Step-by-step explanation:
Given the simultaneous equation;
-6x+5y=1..... 1
6x+4y=10.... 2
Add both equations
5y + 4y = 1+10
9y = 11
y = 11/9
Substitute y = 11/9 into 1;
From 1;
-6x+5y=1.
-6x + 5(11/9) = 1
-6x + 55/9 = 1
-6x = 1- 55/9
-6x = (9-55)/9
-6x = -46/9
x = -46/-54
x = 23/27
The solution to the system of equation is (23/27, 11/9)
