Use properties of operations to simplify this algebraic expression. 5(x-4)+3x-9x+7

step 1: rewrite the subtraction operations as addition of negative numbers.

step 2: use the distributive property.

step 3: use the commutative property of addition to reorder terms so that like terms are together.

step 4: use the associative property of addition to group like terms.

step 5: simplify.

x = -27

Step-by-step explanation:

Apply the Distributive Property to 5(x - 4):  5x - 20.  

Then we have 5x - 20 + 3x - 9x + 7.

Combining like terms, we get -x = 7 + 20 = 27, so that x = -27.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
