Answer:
{x = 1/7
,y = 1
Step-by-step explanation:
Solve the following system:
{-5 y = -5 | (equation 1)
{7 x + 6 y = 7 | (equation 2)
Swap equation 1 with equation 2:
{7 x + 6 y = 7 | (equation 1)
{0 x - 5 y = -5 | (equation 2)
Divide equation 2 by -5:
{7 x + 6 y = 7 | (equation 1)
{0 x+y = 1 | (equation 2)
Subtract 6 × (equation 2) from equation 1:
{7 x+0 y = 1 | (equation 1)
{0 x+y = 1 | (equation 2)
Divide equation 1 by 7:
{x+0 y = 1/7 | (equation 1)
{0 x+y = 1 | (equation 2)
Collect results: Answer: {x = 1/7
,y = 1
Answer:
Step-by-step explanation:
We can use the square property to find the product or just use the distributive property to find the given product. Result will be the same in both cases.
Using the square property:
Using this rule on given expression, we get:
Thus the product of given expression is:
I believe it is g(5) = 27 because if you look at the table in the x column when x=5, g(x)=27
