X^2-2x=-8 add 1 to both sides
x^2-2x+1=-7 now the left side is a perfect square
(x-1)^2=-7 take the square root of both sides
x-1=±√-7 add 1 to both sides
x=1±√-7 which is
x=1±i√7 so
x=1+i√7 and 1-i√7
Answer:
g(x)=2x+4
Step-by-step explanation:
The vertex is (0,1) of the original graph to move the vertex up by 3 units just add 3 to the y-intercept.
Answer:
y = 1
x = -0.75
Step-by-step explanation:
The alternate angles theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles are equal.
21y - 1 = 4x + 23
21y - 24 = 4x
5.25y - 6 = x
21y - 1 = 4x + 23
21y = 4x + 24
y = 4/21(5.25 - 6) + 1.14
y = 1 - 1.14 + 1.14
y = 1
5.25(1) - 6 = x
-0.75 = x
Answer:
-2
Step-by-step explanation:
3(-3)^2+5(-3)-14
27-15-14=-2
Answer:
x= -15, 5
Step-by-step explanation:
x²+10x-75=0
x²+15x-5x-75=0
(x+15)(x+5)=0
x= -15 and x=5
