Step-by-step explanation:
26/8=3.25
Answer:
5808.8km
Step-by-step explanation:
Vertex form is
where (h,k) is the vertex.
We can see that the vertex of the graph is at (2,0), and that the graph opens downwards, but does not look stretched at all.
Therefore,
a = -1
h = 2
k = 0
and our vertex form equation is
which is answer A
Answer:
x = 5
Step-by-step explanation:
6x - 2(x + 4) = 12 use distributive property
6x + (-2)(x) + (-2)(4) = 12
6x - 2x - 8 = 12 add 8 to both sides
4x = 20 divide both sides by 4
x = 5
Answer:
None.
Step-by-step explanation:
6x-20=32
6(8)-20=48-20=28, not 32
--------------------------------------
16-x=12
16-8=8, not 12
--------------------
20-0.4x=13.8
20-0.4(8)=20-3.2=16.8, not 13.8
------------------------------------------------
1x+12=30
x+12=30
8+12=20, not 30
