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
Finding the sol'n to f(x) - g(x) = 0 is the same as finding the solution of f(x)=g(x). You could do this analytically by setting the actual function f(x) = g(x) and solving for x (and then for y), or you could estimate the solution from the given graph. The two lines intersect at approx. x=-3.75, y=2.5.
Answer:
$1.45
Step-by-step explanation:
9.25 - 2 = 7.25
7.25 ÷ 5 = 1.45
Answer:
i believe its 8
8 is the largest number i can think of that is a factor of both of those number
Answer:
3, 12, 27,48, 75, 108, 147
Step-by-step explanation:
12-3 = 9
27-12 = 15 (9+6)
48-27 = 21 (15+6)
75-48 = 27 (21+6)
108-75 = 33 (27+6)
147-108 = 39 (33+6)
