Draw out a number line. Make sure 4 is on the number line. At this location, plot an open circle. The open circle indicates "do not include this endpoint as part of the solution set". We shade to the right of this open circle.
Visually this describes all real numbers that are larger than 4.
Answer:
Well
If we choose plan B then it would be better. 15 cents a messages would be 3 messages in total if we choose plan b.
Step-by-step explanation:
Answer: $8.60
Step-by-step explanation:
Let the price of a bread = x
Let the price of a tarts = x - 1
If 3 times the price of a loaf of bread is $29.5 more than half of the price of a box of tarts. This can be represented as:
3 × x = 1/2 × (1 - x) + 29.5
3x = 0.5 - 0.5x + 29.5
3x + 0.5x = 29.5 + 0.5
3.5x = 30
x = 30/3.5
x = 8.6
The explicit formula of the arithmetic sequence:
d - common difference
We have the recursive formula of an arithmetic sequence:
Therefore we have:
Substitute:
<h3>Answer: aₙ = 7 - 3n</h3>
