Answer:
9
Step-by-step explanation:
The answer to | − 12 + 3 | is 9 because if you add -12 + 3, you get -9. However, since it is the <em>absolute value</em>, we would make it the same number but positive.
Hope this helped! :)
He pays $223.65.
This is because from the equation you know that he pays 29.95+2.00 for one light therefore, if we use x to represent the amount of lights--
X(29.95+2.00)
is an equation you can use to solve for the amount Mr. Davis payed for his lights.
Answer:
Graph A
Step-by-step explanation:
if you look at the numbers on the top row they correspond with the left side of the graph and the bottom row of numbers correspond with the bottom of the Graph.
Answer:
x = 0
Step-by-step explanation:
= 2 - x ( square both sides to clear the radical )
x + 4 = (2 - x)² ← expand using FOIL
x + 4 = 4 - 4x + x² ( subtract x + 4 from both sides )
0 = x² - 5x ← factor out x from each term
0 = x(x - 5)
equate each factor to zero and solve for x
x = 0
x - 5 = 0 ⇒ x = 5
As a check
substitute these values into the equation and if both sides are equal then they are the solutions
x = 0
left side = = = 2
right side = 2 - 0 = 2
then x = 0 is a solution
x = 5
left side = = = 3
right side = 2 - 5 = - 3 ≠ 3
then x = 5 is an extraneous solution
