Answer:
Line y = -x + 2 intersects line y = 3x + 1
Step-by-step explanation:
The solution to a system of equations is the point at which the two lines intersect. To find this point, first equate the equations and solve for x:
Substitute the found value of x into one of the equations, and solve for y:
Therefore, the solution to the system of equations (the point at which the two lines intersect) is:
So the description that best describes the solution to the system of equations is:
Line y = -x + 2 intersects line y = 3x + 1
Answer:
(1, 0 )
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x = 
, then
y = 
(x + 2) - 1
to find the zero let y = 0 , that is
(x + 2) - 1 = 0 ( add 1 to both sides )
(x + 2) = 1 , then
x + 2 = 
= 3 ( subtract 2 from both sides )
x = 1
the zero is (1, 0 )
Answer:
9/12
Step-by-step explanation:
because I is the biggest number
P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2
-15 and -42 both add to -57 and multiply to 630
