Does the system shown always, sometimes, or never have a solution when a > b?

AysviL [449]

Answer:

always have a solution

Step-by-step explanation:

A linear equation in standard form is given by:

Ax + By = C, where A,B, C are real numbers and A,B is not equal to zero.

Two linear equations with equations Ax + By = C and Dx + Ey = F

Therefore the first equation becomes: (A/B)x + y = C/B and the second equation becomes (D/E)x + y = F/E ]

Both equations are said have a solution if A/B ≠ D/E, they have no solution if A/B = D/E and they have infinite solutions if A/B = D/E, C/B = F/E.

Given that:

when a > b

ax + y = 8

bx + y = 5

Since a ≠ b, but a > b, the system has a solution

Solve for x ... please help

Mrac [35]

Answer:

$7x + 49 \degree = 2x + 94\degree \\ 7x - 2x = 94\degree - 49 \degree \\ 5x = 45\degree \\ x = \frac{45}{5} \\ x = 9 \\ check \\ 7(9) + 49 = 112\degree \\ 2(9) + 94 = 112\degree$

Valentin [98]

Answer:

a) $H_{0} = 9.5$

b) $H_{a} < 9.5$

Step-by-step explanation:

The National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness.

At the null hypothesis, we test if the value we find is equal to the expected value, that is:

$H_{0} = 9.5$

Test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population

Lower, which means that the alternate hypothesis, we test if the value we find is lower than the expected value, that is:

$H_{a} < 9.5$

Well percents are probability, and probability is similar to theory. So i think its theoritical probability.

Hope this helps.
