A
Step-by-step explanation:
I think it is A but I am not to sure it is either A or B
Answer:
9a+20=7a-20
2a=4-20
a=2-10
A= -8
Step-by-step explanation:
The 1 is in the whole number's place so the first number would be 1. the 5 is in the tenths place so the value of the number would be 50, the 9 is in the hundreths so the value of the number would be 900, so the mixed number would be 1 and 59/100.
theres the points for you
We need to write the equation in its vertex form so we have to know the general equation for the vertex form. It is written as:
y = (x - h)^2 + k
where h and k represents the point of the vertex.
We go as follows:
y = (x^2 + 4x) – 3
y +4= (x^2 + 4x+4) – 3
y = (x + 2)^2 - 7
Therefore, the correct answer from the choices is option B.
