Answer:
The explicit form for this sequence is 
for all 
.
Step-by-step explanation:
The explicit form of an arithmetic sequence of numbers is given by the formula 
, where 
is the first term of the sequence, 
is the difference between two consecutive terms of the sequence, and .
We know that the first four elements for the arithmetic sequence are 
.
To find the general formula for this problem we only need to calculate in the above formula.
For n=2, we have
if we replace 
and 
and solve for we obtain
Therefore the explicit form is for all .
4r + 5 = 3 is not an algebraic expression because expressions are basically equations but WITHOUT answers. In this equation, 3 is shown as the answer, which makes it an equation, not an expression.
Hope this helps! Please correct me if I'm wrong! :D
Answer:
- 3 ≤ x < 0
Step-by-step explanation:
- 3 is included in the set thus x can equal - 3
- 3 is less than all other values in the set including the largest value of 0, thus
- 3 ≤ x < 0
Answer:
A and D
option A is correct because if you do 4/5 times 2/2 you get 8/10
so that means they both are Equal.
option D is also correct
because
after 6/10 It’s 7/10, 8/10..
Answer:
90°
Step-by-step explanation:
EG is a straight line
EG = EHD + DHG
DHG is a 90 degree angle
180 = EHD +90
Subtract 90 from each side
180-90= EHD +90-90
90 = EHD
The arc has the same measure as the angle since it is from the center
arc ED = 90
