➷ 9=5x-3+9
First, you would need to combine the like terms.
-3+9 = 6
9=5x+6
Next, you subtract 6 on both sides.
3=5x
Finally, you divide 5 on both sides to isolate x.
3/5=x
Final answer:
x=3/5

Answer:
(5,-6)
Step-by-step explanation:
ONE WAY:
If 
, then 
.
Let's simplify that.
Distribute with 
:
Combine the end like terms 
:
Use 
identity for 
:
Combine like terms 
and 
:
We are given 
.
So we have that 
.
The vertex happens at 
.
Compare 
to 
to determine 
.
Let's plug it in.
So the 
coordinate is 5.
Let's find the corresponding 
coordinate by evaluating our expression named 
at 
:
So the ordered pair of the vertex is (5,-6).
ANOTHER WAY:
The vertex form of a quadratic is 
where the vertex is 
.
Let's put 
into this form.
We are given .
We will need to complete the square.
I like to use the identity 
.
So If you add something in, you will have to take it out (and vice versa).
So we have in vertex form is:
.
The vertex is (3,-6).
So if we are dealing with the function .
This means we are going to move the vertex of right 2 units to figure out the vertex of which puts us at (3+2,-6)=(5,-6).
The coordinate was not effected here because we were only moving horizontally not up/down.
Answer:
<h3>FALSE</h3>
Step-by-step explanation:
Given the polynomial f(x) divided by x-4
To check whether the remainder will be equal to f(-4), we need to get whether the value of x is -4 if we set x-4 to zero as shown;
x- 4 = 0
Add 4 to both sides
x - 4 + 4 = 0+4
x = 4
<em>Since the value of x is 4 not -4 hence the remainder will NOT be equal to f(-4). The answer is false</em>
