Answer:
5-(-7)=5+7
Step-by-step explanation:
keep in mind that two negatives make a positive. therefore it would be 5+7=5+7. i hope this helps :)
Answer:
See below
Step-by-step explanation:
<u>Recursive Formula for Arithmetic Sequences</u>
- <u />
- represents the nth term
- represents the preceding term
- represents the common difference
<u>Explicit Formula for Arithmetic Sequences</u>
- <u />
- represents the nth term
- represents the 1st term
- represents the common difference
<u>Ernest's Schedule Recursive Formula</u>
We can see that the common difference is because for each week, Ernest swims 0.25 more kilometers than the preceding one. Therefore, the recursive formula for Ernest is
<u>Ernest's Schedule Explicit Formula</u>
Given our common difference from earlier and the fact that is our first term, the explicit formula for Ernest is
<u />
<u>Denise's Schedule Recursive Formula</u>
We can see that the common difference is because for each week, Denise swims 0.5 more kilometers than the preceding one. Therefore, the recursive formula for Denise is
<u>Denise's Schedule Explicit Formula</u>
Given our common difference from earlier and the fact that is our first term, the explicit formula for Denise is
Answer:
speeds above 343 m/s
Step-by-step explanation:
the faster you go the faster the supersonic
The origins of algebra can be traced to the ancient Babylonians, who developed a positional number system that greatly aided them in solving their rhetorical algebraic equations.
