Solve |5x + 15| = 10x. Identify the solution and an extraneous solution.
A. Solution: x= 3; extraneous solution: x=-3
B. Solution: x= 3; extraneous solution: X=-1
c. Solution: x= 1; extraneous solution: X=-3
D. Solution: ×= -1; extraneous solution: X=3
If 5x + 15 ≥ 0, then |5x + 15| = 5x + 15. The equation reduces to
5x + 15 = 10x
15 = 5x
x = 3
If instead 5x + 15 < 0, then |5x + 15| = -(5x + 15), and the equation becomes
-5x - 15 = 10x
-15 = 15x
x = -1
If x = 3, then |5x + 15| = 30 and 10x = 30, so x = 3 is a valid solution.
If x = -1, then |5x + 15| = 10 while 10x = -10, so x = -1 is the extraneous solution.
The cost to rent an rv is $150 per day plus $0.35 per mile. what is the maximum distance you can drive the rv in a day if your budget is $200?
Answer:
142.86 miles
Step-by-step explanation:
150 + .35m < 200
150 + .35m -150 < 200-150
.35m < 50
.35m/35 < 50/.35
m < 142.86
The maximum distance I can drive the rv in a day if my budget $200 is, approx. 142 miles
What are inequalities?Inequalities are the comparison of mathematical expressions, whether one quantity is greater or smaller in comparison to another quantity.
We use these symbols to represent inequalities, '>' , '<', '≥', '≤'
Given that,
The cost to rent an rv is $150 per day + $0.35 per mile
The maximum distance in a day = ?
Budget is $200
So,
The maximum distance in a day ≤ 200
The maximum distance in a day = 150 + 0.35x
Now,
⇒ 150 + 0.35x ≤ 200
⇒ 0.35x ≤ 200 - 150
⇒ x ≤ 142.85
Hence, maximum distance in a day is approx. 142 miles

The height of the building to the nearest tenth of a meter is; 13 m
How to make use of Cosine Rule?The slant line from the top of Trevor's head to the base of the building is gotten from Pythagoras theorem;
15/x = sin 36°
x = 15/sin 36
x = 25.52 m
Angle between that slant line and base of building is;
90 - tan⁻¹(1.5/14) = θ
θ = 83.88°
Remaining angle of the bigger triangle is;
180 - (36 + 83.88) = 60.12°
Thus, if the height of the building is h, then;
h/sin 36 = 25.52/sin 60.12

Job 2 is a better choice because the annual income after rent and utilities is $59,700 but that of job 1 is $55,575.
Job 2 is a better choice because the annual income after rent and utilities is $45,400 but the income for job 1 is $41,900.
Job 1 is a better choice because it costs $4,500 less per year to live there.
The jobs have equal annual incomes of $45,400 after rent and utilities so Caitlin should take the job in her favorite locale.
D) Caitlin should take the position in her preferred location because the annual salary is $45,400 after rent and utilities.
What is meant by annual income?To calculate your annual salary, multiply your gross income (before taxes) by the number of pay periods in a year. If an employee earns $1,500 each week, his or her annual income is $1,500 x 52 = $78,000.
Job 1 and Job 2 both generate the same or similar amount of income of $45,400 per year after additional expenses.
This means that Caitilin should choose her career based on the preferences of her neighboring neighborhood so that she can travel easily.
This is because moving to a more distant job location would result in no increase in her income, making it nonsensical to do so.

Hey there!
Arithmetic sequences are made up of terms that are added or subtracted, and geometric sequences are made up of terms that are multiplied or divided.
Given this info, we can see that we go from 10 to -5. Because we know that this is geometric, we see that we must divide by -2 in our sequence.
We can see that this is true because -5/-2=5/2.
Now, we could simply continue dividing by negative two to get our answer, which is -5/16.
You could easily do that with a calculator, but if you had to find a term that was farther from the first term, that would take forever to do with a calculator, so there is an equation that you can use and plug in your numbers to find the answer quickly.
