x=0.y=3
5x-y=-3
y=5x+3
sub y=5x+3 into 6x+y=3,
6x+5x+3=3
11x=0
x=0
6(0)+y=3
y=3
Round 34 down to 30 then round 39 up to 40
34 ⟶ 30 34 is rounded down to 30
39 ⟶ 40 39 rounded up to 40
34 ⟶ 30
39 ⟶ 40
34 is rounded down to 30
39 rounded up to 40
Calculate mentally 34 × 39 = 1326
The estimated product is 1326.
Sequence: 1, 3, 6, 10, 15, …
If sequence is arithmetic,
If sequence is geometric,
<u>Check </u>for arithmetic:
Hence, the sequence is not arithmetic
<u>Check </u>for geometric:
Hence, the sequence is not geometric
