Answer:maybe 0.75
Step-by-step explanation:
Hello :
y = 3x²+9x
= 3(x² + 3x )
= 3 ( x² +2(3/2)x +(3/2)²) -(3/2)²)
= 3((x+3/2)² -9/4)
y = 3 (x+3/2)² -27/4
<span>the x-coordinate of the vertex is : - 3/2</span>
Answer:
6.552×10³×10
6.552×10^3+1
6.552×10^4 is the standard form
i hope this will help you :)
Answer:
22
Step-by-step explanation:
if a=15
then, 2(a-5)+2= 2(15-5)+2 = 2(10)+2= 20+2=22
Answer:
x=23
Step-by-step explanation:
let's make this question into equation form
x increase by 10; or x+10
is equal to 33; or =33
so it would look like this; x+10=33
now we can solve it in reverse
<em>33-10=23</em> so x is 23.
hope this helped, have a great day.
