Answer:
x=10
Step-by-step explanation:
Answer:
84 + x*1 = 8x
Step-by-step explanation:
Xavier needs to sell 12 painting to break even.
2x+4=24
-4 -4
-------------
2x=20
÷2 ÷2
----------
X=10
So 10 stickers in each pack
Given the function h(x)=x^2+14x+41, to solve by completing square we procced as follows;
x^2+14x+41=0
x^2+14x=-41
but;
c=(b/2)^2
and b=14
hence;
c=(14/2)^2=49
substituting the value of c in the expression we get:
x^2+14x+49=-41+49
x^2+14x+49=8
(x+7)^2=8
this can be written in vertex form;
h(x)=a(x-h)^2+k
where:
(h,k) is the vertex;
thus
(x+7)^2=8
h(x)=(x+7)^2-8
hence the vertex will be at the point:
(-7,-8)
