Answer:
ok but wheres point A and where's Q
Step-by-step explanation:
Answer:
x = -7
, y = 0
Step-by-step explanation:
Solve the following system:
{4 x + 5 y = -28 | (equation 1)
-4 x - 7 y = 28 | (equation 2)
Add equation 1 to equation 2:
{4 x + 5 y = -28 | (equation 1)
0 x - 2 y = 0 | (equation 2)
Divide equation 2 by 2:
{4 x + 5 y = -28 | (equation 1)
0 x - y = 0 | (equation 2)
Multiply equation 2 by -1:
{4 x + 5 y = -28 | (equation 1)
0 x+y = 0 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{4 x+0 y = -28 | (equation 1)
0 x+y = 0 | (equation 2)
Divide equation 1 by 4:
{x+0 y = -7 | (equation 1)
0 x+y = 0 | (equation 2)
Collect results:
Answer: {x = -7
, y = 0
Answer:
-84 + 10i
Step-by-step explanation:
first, you want to take out the negative symbol from the square root, and we know that i = sqrt(-1) (sqrt = square root)
so the equation would look like
i x sqrt(100) - 84
solve for the square root of 100 which is 10
now the equation is
10i - 84
that is the answer and you can flip the equations so it can look like the actual answer
-84 + 10i
