Answer:
Solution set = (-5, -2)
Step-by-step explanation:
Given equations;
-7x + 8y = 19 ------------- eq1
7x – 9y=-17 --------------- eq2
Adding both equations:
-y = 2
OR
y = 2
Put value of y in eq2:
7x - 9(-2) = -17
7x + 18 = -17
7x = -17 -18
7x = -35
x = -5
Solution set = (-5, -2)
i hope it will help you!
Well 7 goes into 15 7 times and theres one left over so there would be one left out
Answer:
x=22
Step-by-step explanation:
break it down:
55-11 = 44
so 44/2 = 22
therefore
x=22
Answer:
y = -1x - 6 is the equation of the line.
Step-by-step explanation:
1. Insert the coordinates into the formula:
-7 = -1 ( 1 ) + b
2. Solve both sides and add 1 to each side to get:
-6 = b
3. If the slope is -1 and the y-intercept (b) is -6, than the equation of the line is:
y = -1x - 6
