Write an equation of a line that goes through the point (2,3) and has a slope of -1

y = -1x + 5

Step-by-step explanation:

First, this is your current equation: y= -1x + b. Plug in the point to the equation to get this: 3 = -1(2) + b. Multiply -1 by 2 to get -2. It should look like this: 3 = -2 + b. Add 2 to both sides of the equation to get 5 = b. Go back to your original equation and plug 5 in for b. This is your final equation: y = -1x + 5. Hope this helped!

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

my answer is$ 12

step-by-step explanation:

because 15 -2=12
