Explanation:
Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.
The actual slope is ...
slope = Δy/Δx = 6/2 = 3
Area of triangle= 1/2(bh)
So u do the reverse to find the base
48 x 2 which equals 96
Then u divide
96 divided by 8 = 12
Length of base equals 12
Answer:
System 1 : {3,0}; System 2 : {6,-2}
Step-by-step explanation:
2x + 3y = 6
-2x - y = -6
2y = 0
y = 0
-2x = -6
x = 3
system 2
2x + 3y = 6
2x + 2y = 8
y = -2
2x -4 = 8
2x = 12
x = 6
Simplifying radical expressions expression is important before addition or subtraction because it you need to which like terms can be added or subtracted. If we hadn't simplified the radical expressions, we would not have come to this solution. In a way, this is similar to what would be done for polynomial expression.
