2x - y = 5 x + 3y = 7 what is the value of the system determinant?

 The required value of the system determinant is 7.

Step-by-step explanation:  We are given to find the value of the system determinant for the following system of linear equations :

We know that

the first column of the system determinant contains the coefficients of the unknown variable x and the second column contains the coefficients of the unknown variable y.

So, the system determinant can be written as

Thus, the required value of the system determinant is 7.

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
