Answer:
13
Step-by-step explanation:
The x value of the vertex in
ax^2+bx+c is -b/2a
y value is just sub for x
3x^2-6x+5
x value of vertex is -(-6)/(2*3)=6/6=1
sub back
y=3(1)^2-6(1)+5
y=3(1)-6+5
y=3-1
y=2
vertex is (1,2)
Answer:
Step-by-step explanation:
Multiply both sides by 10:
Multiply both sides by 7:
Expand using distributive rule:
Hence,
Therefore, .
