Answer:
x = 5
, y = 0
Step-by-step explanation by elimination:
Solve the following system:
{-6 x - 8 y = -30 | (equation 1)
4 x + 2 y = 20 | (equation 2)
Add 2/3 × (equation 1) to equation 2:
{-(6 x) - 8 y = -30 | (equation 1)
0 x - (10 y)/3 = 0 | (equation 2)
Divide equation 1 by -2:
{3 x + 4 y = 15 | (equation 1)
0 x - (10 y)/3 = 0 | (equation 2)
Multiply equation 2 by 3/10:
{3 x + 4 y = 15 | (equation 1)
0 x - y = 0 | (equation 2)
Multiply equation 2 by -1:
{3 x + 4 y = 15 | (equation 1)
0 x+y = 0 | (equation 2)
Subtract 4 × (equation 2) from equation 1:
{3 x+0 y = 15 | (equation 1)
0 x+y = 0 | (equation 2)
Divide equation 1 by 3:
{x+0 y = 5 | (equation 1)
0 x+y = 0 | (equation 2)
Collect results:
Answer: {x = 5
, y = 0
That’s false because two lines are to short so it’s false
Answer: y = mx + b
Step-by-step explanation:
i think this is what ur asking but “y” is the coordinate of the y-axis with “x” being the coordinate of the x-axis. m is the slope of the graph
Answer:
Step-by-step explanation:
What is it
Answer:
BC, DB, CD
Step-by-step explanation:
The side opposite the largest angle must be the largest side and the side opposite the smallest angle must be the shortest. 96 degrees is opposite CD and 30 degrees is opposite BC.
