Answer:
it is 9
Step-by-step explanation:
the common difference is 9
Answer:
y=7
Step-by-step explanation:
x = -1 x is one , replace x with negative one in the equation. using the order of operation PEMDAS.
Remember this -1³= -1×-1×-1=-1
-1²=-1×-1=1.
y =8x³+12x²-6x-3
y= 8(-1)³+12(-1)²-6(-1)-3
<h3>Exponents</h3>
y= 8(-1)+12(1)-6(-1)-3
<h3>Multiplication</h3>
y= -8+12+6-3
<h3>Addition</h3>
y= 10-3
<h3>Subtraction</h3>
y= 7
<h3>Therefore y= 7</h3>
Hello there.
To answer this question, we need to remember some properties about the vertex of quadratic functions.
Let 
. Its vertex can be found on the coordinates 
such that 
and 
, in which 
.
Using the coefficients given by the question, we get that:
Thus, we have:
So the statement is true, because the 
coordinate of the vertex of the function is equal to 
Put together the like terms, -k + kh + h. -k is -5 they are both negatives so it would be +5. 5 +kh +h. Next is 5 + -5 x -2. Two positives make a negative so it's 5 + -5 x -2, -5 x -2= 10 + 5 =15. so your answer is 15
