Answer:
(-6, -36)
Step-by-step explanation:
The vertex of a function of the form is given by the formula:
in other words, we find h and then evaluate function at h to find k.
We know from our function that , .
Replacing values
Now we can evaluate our function at -6 to find k:
We can conclude that the vertex (h, k) of our function is (-6, -36)
Well, the above statement is true so it is not the associative properties because they are just switched around.
What is being demonstrated is the commutative property of addition.
Answer:
7² · (16 - 4 · 2) - 40 = 352
Step-by-step explanation:
Order of operations: PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
7² · (16 - 4 · 2) - 40
7² · (16 - 8) - 40
7² · (8) - 40
49 · 8 - 40
392 - 40
352
First Equation
STEP 1: Move the variable to the right side and change its sign
3x=8-y
STEP 2: Divide both sides of the equation by 3
x=8/3 - y/3
STEP 3: Write all numerators above the common denominator
x=8-y/3
THE FINAL ANSWER IS:
x=8-y/3
Second Equation
STEP 1: Move variable to the right side and change its sign
-x= -10+2y
STEP 2: Change the signs on both sides of the equation
x=10-2y
THE FINAL ANSWER IS:
x=10-2y
