Answer:
Step-by-step explanation:
.
Here, we are required to find how many hours per week does Lindsey need to study if she wants to have an average of at least 90
Lindsey needs to study for at least 15.25 hours to have an average of 90
Given expression:
4(h + 11) – 15
Where,
h = number of hours
For Lindsay to have at least 90
4(h + 11) – 15 = 90
open parenthesis
4h + 44 - 15 = 90
4h + 29 = 90
4h = 90 - 29
4h = 61
Divide both sides by 4
h = 61/4
h = 15.25 hours
Therefore,
Lindsey needs to study for at least 15.25 hours to have an average of 90

Answer:
In the year 2019 the number of new cars purchased will reach 15,000.
Step-by-step explanation:
t = 0 corresponds to the number of new cars purchased in 1998. If that is so, we can determine t ( time ) by making our quadratic equation here equal to 15,000 - considering that we want the year the number of cars reaches this value. t here is only the number of years to reach 15,000 cars, so we would have to add that value to 1998, to see the year that the cars will reach 15,000.
The " set up " should look like the following quadratic equation -
20t² + 135t + 3050 = 15,000 - Isolate 0 on one side,
20t² + 135t - 11950 = 0 - From here on let us solve using the quadratic equation formula,
,
... now as you can see we have two solutions, but time can't be negative, and hence our solution is the first one - about 21.3 years. 1998 + 21.3 = ( About ) The year 2019. Therefore, in the year 2019 the number of new cars purchased will reach 15,000.
