algebra please help rewrite the polynomial in the form ax+by+c and then identify the values of a, B, and C x-1-2y

x-2y-1; a = 1, b = -2, c = -1

Step-by-step explanation:

To rewrite it into the specified form, all you have to do is just shift the variables.

To find the coefficients, just look at the number that is stuck to the variable, if there is none, then the coefficient is just one.

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
