Answer:
x = - 1 and x = 5
Step-by-step explanation:
Given
(x - 3)² + 2(x - 3) - 8 = 0
Let u = x - 3, then
u² + 2u - 8 = 0 ← solve for u
(u + 4)(u - 2) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 4 = 0 ⇒ u = - 4
u - 2 = 0 ⇒ u = 2
Convert back to x, that is
x - 3 = - 4 ( add 3 to both sides ) ⇒ x = - 1
x - 3 = 2 ( add 3 to both sides ) ⇒ x = 5
That is distributive property ... hope this helps
Answer: c) y=1/5x
Step-by-step explanation: took da test
I am absolutely sure that the task <span> b = 3, then 3x + y = 1 and bx - y = 3 is NOT parallel, which means that the statement represented above is FALSE.
To make sure you can check it using : </span>
Hope now it's obvious. Regards!
Answer:
12/5
Step-by-step explanation:
m= slope
m=Y2-Y1/X2-X1
Y2=5, Y1=-7, X2=3, X1=-2
Substitute into equation
m=5-(-7)/3-(-2)
m=5+7/3+2
m=12/5
slope is 12/5
