Answer:
7x^2+4x-8=14
can be rewritten as
0=7x²+4x-22
everything divided by 7 to normalize
0=x²+4/7x+22/7
now throw the pq formula on this. We can treat it as a function.
the x-intercepts would be on
wait. there are indeed no real-number-solution to satisfy the given equation.
no x-intercepts, no solution. no numbers to put in for x so that the equation gives true results.
no solution in real numbers.
Have a nice day

If there are questions left, feel free to ask them
p.s. is this about imaginary numbers at university level?
You will read for 45 minutes if your brother reads for 15 minutes.
<em><u>Explanation</u></em>
You decide to read 30 minutes longer than your brother reads.
If your brother reads number of minutes, then 30 minutes longer than minutes means minutes.
As the number of minutes you read is , so the equation will be:
When your brother reads for 15 minutes, then we will just <u>plug into the above equation</u>. So.....
So, you will read for 45 minutes if your brother reads for 15 minutes.

Answer:
Step-by-step explanation:
This could be an observational study because an experiment was not carried out by the research to further verify this hypothesis. Individuals are observed and data is collected from such observation. No effort is made by the researcher to affect the outcome of such results.
This study alone is not enough to conclude about a cause and effect relationship between steroids and the increase in home runs as thus study is not randomized and cant control other factors or links bringing about this result.
