The axis of symmety is the x value of the vertex
to find the x value of the vertex of ax^2+bx+c=0
x value=-b/2a
3x^2+bx+4=0
3/2=vertex
-b/2(3)=3/2
-b/6=3/2
times 6
-b=18/2
-b=9
times -1
b=-9
4x-1=18
4x=18+1
4x=19
x=19/4
X = -2.5 because:
-7.6+5.1= -2.5
Answer:
X = - 2
John had solve the equation 4x+(-3)=-11, he said's his answer is x = 2.
Is he wrong or correct? If wrong plz show the steps on how to get the right answer.
Step-by-step explanation:
4x+(-3)= -11
-11 + 3
= -8
We got x by itself
now solve for x
4x = -8
Solution
X = -2
Answer:
5a-25=70
5a=70+25
a=95/5
a=19
Step-by-step explanation:
since a(b+c) = ab+ac
