Answer:
7n - 1
Step-by-step explanation:
notice that the difference between adjacent terms is 7.
so nth term is given by:
nth term = first term + (n-1)×difference (n is any number)
= 6 + (n-1)7
= 6+ 7n -7
= 7n - 1
hope this helps :-))
Answer:
x=8
Step-by-step explanation:
Answer:
AB
Step-by-step explanation:
Given:
BC = BD
DE is ⊥ to AC.
GB is ⊥ CD.
we need to find the median from the given figure.
Solution:
By Definition of Median which states that;
" a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.."
From the above figure we can see that;
Segment AB bisects the opposite side CD.
Also BC = BD (given)
Hence segment AB is a median.
The slope of the line appears to be about 30/4 = 7.5. Since it starts at y=10 for x=0, the equation of the line is
y = 10 +7.5x
For x=7, the value of y (Linda's score) will be
y = 10 + 7.5*7 = 10 + 52.5 = 62.5
Linda's approximate math score for 7 hours' study will most likely be
62.5 points
1.)divide by 5 on each side to obtain
Abs(2x+3)=45
2x+3=45 or 2x+3=-45
2x=42 or 2x=-48
x=21 or x=-24
