Answer:
Step-by-step explanation:
Subtracting 4x from both sides of the inequality.
Simplifying the inequality.
Answer:
83.75$
Step-by-step explanation:
(5×11.75)+5×(5)=?
5×(11.75+5)=? [DISTRIBUTIVE PROPERTY]
5×16.75=?
83.75
-------------------------------------------------------
Equation Given :
-------------------------------------------------------
16x² = 121
-------------------------------------------------------
Take away 121 from both sides:
-------------------------------------------------------
16x² - 121 = 0
-------------------------------------------------------
Make each term a perfect square
--------------------------------------------------------
(4x)² - (11)² = 0
--------------------------------------------------------
Apply algebraic rule : a² - b² = (a + b)(a - b)
--------------------------------------------------------
(4x + 11) (4x - 11) = 0
-------------------------------------------------------
Apply zero product property :
-------------------------------------------------------
4x + 11 = 0 or 4x - 11 = 0
--------------------------------------------------------
Solve for x :
--------------------------------------------------------
4x = - 11 or 4x = 11
x = -11/4 or x =11/4
--------------------------------------------------------------------------
Answer: x = -11/4 or x = 11/4
--------------------------------------------------------------------------
D. Symmetric Property. If you flip it the = sign will be on the end
