Simplify. Identify any x value for which the expression is undefined x^2+3x/x^3
Answer:
x = 0
Step-by-step explanation:
I think you mean
[tex] \dfrac{x^2 + 3x}{x^3} [/tex]
The only undefined values of x come from the denominator, x^3.
A denominator cannot equal zero since division by zero is undefined.
Therefore if x^3 equals zero, you get an un defined expression.
We let x^3 = 0 and solve for x to find the values of x that would cause an undefined expression.
x^3 = 0
Solve for x by taking the cubic root of both sides.
x = 0
Answer: x = 0

Activity
Rylee shopped at a clothing store, where she spent $36.50 plus 8% tax. Then, she spent $25 to refuel her car at the gas station. Finally, she bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase.
Complete the following steps to help Rylee find the net change to her banking account balance.
Part B
Write an expression that represents the net change in Rylee’s bank account balance after paying for fuel at the gas station.
Part C
Use decimal numbers to write an expression that represents the net change in Rylee’s bank account balance after paying for groceries.
Part D
Finally, use decimal numbers to write an expression that represents the net change in Rylee’s bank account balance for her entire shopping trip. Use your answers from parts A through C to guide you.
Part E
Simplify the expression in part D to find the net change in Rylee’s bank account balance. Express your answer as a decimal number.
Answer:
A)
Rylee bought $36.50 in clothes. This money is leaving her bank account, so represent the amount with a negative sign: -$36.50.
The tax on her purchase is 8%, so the tax amount is 0.08 × -$36.50. The expression that represents the net change in her bank account is -$36.50 + (0.08 × -$36.50).
Further simplify the expression by factoring -$36.50 from both terms:
-$36.50 + (0.08 × -$36.50)
=
-$36.50(1 + 0.08)
=
-$36.50(1.08).
B)
Rylee spent $25 for fuel at the gas station. This money is leaving her bank account, so represent the amount with a negative sign: -$25.
C)
The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign: -$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is -$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2) = -$23.50(1 – 0.2)
= -$23.50(0.8).
D)
clothing store:
-$36.50(1.08) or -$36.50 + (0.08 × -$36.50)
gas station:
-$25
grocery store:
-$23.50(0.8) or -$23.50 – (-$23.50 × 0.2)
After adding the three expenses:
-36.5 + (-36.5)(0.08) + (-25) + (-23.5) − (-23.5)(0.2) or
(-36.5)(1.08) + (-25) + (-23.5)(0.8).
E)
(-36.5)(1.08) + (-25) + (-23.5)(0.8) = -$83.22

Solve each proportion 2/r=12/18
Answer:
r = 3
Step-by-step explanation:
starting with
2 / r = 12 / 18. we cross multiply
18 * 2 = 12 * r
36 = 12 * r
and divide by 12 to isolate "r"
36 / 12 = r
Then r = 3

Gym A charges $60 a month plus $4 per visit. The monthly cost at Gym B is represented by y = 4x + 50, where x is the number of visits per month. What conclusion can you draw about the monthly costs of the gyms? Since the rate per visit is less at Gym A , the monthly cost of Gym A is always more than Gym B.
Answer:
Gym A has 56 visits per month and Gym B has 46 visits per month.
Step-by-step explanation:
y=4x+60, which gives us 56
y=4x+50, which gives us 46

74° + 35° + ( 6x + 17° ) = 180°6x + 17° = 180° - 74°- 35°6x + 17° = 180° - 109°6x + 17° = 71°6x = 71° - 17°6x = 54x = 54÷6x = 9MARK ME AS BRAINLIST PLZ FOLLOW METriangles
Given :-A diagram with angles 74°, 35° and ( 6x + 17 )°.
To Find :-Value of x.
Concept Used :-Sum of all angles in a triangle is 180°.
Solution :-Sum of all angles in a triangle = 180°
74° + 35° + 6x + 17° = 180°
6x + 74° + 35° + 17° = 180°
6x + 126° = 180°
6x = 180° - 126°
6x = 54°
x = 9
Answer :-So, value of x is 9.
Explain why it is correct to claim that A/B < B/A is true.
Given: 0 < A < B
I don't know how to explain this
Answer:
Think of it as a small number and a large number. If the large number is being divided by a small number, of course that would be larger than the small number being divided by the large number.
The statement /B < B/A is true if the 0 < A < B because the denominator is small so the value of B/A is larger.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have:
A/B < B/A
If you use the principle that the fraction must not be incorrect and have the value A/B1 (i.e., A and B are both positive), then this is true for positive values.
If A/B = 2/3
Then B/A = 3/2
If A/B < B/A
2/3 < 3/2 (True) if 0 < A < B
5/7 < 7/5 (true) if 0 < A < B
Thus, the statement /B < B/A is true if the 0 < A < B because the denominator is small so the value of B/A is larger.

Graph the line passing through (6,−2) whose slope is m=−3
Answer:
Step-by-step explanation:
When you know the slope m of a line and a point (x₀,y₀) on the line, you can write an equation for the line in "point-slope" form:
y-y₀ = m(x-x₀)
In your case,
y+2 = -3(x-6)
The line is easier to graph if you rearrange the equation to solve for y:
y = -3x+16
You know that (0,16) is one of the points on the line.
Plot the two points that you know, (6,-2) and (0,16), then draw a line through them.
Find the value needed for the “?” to make the equation true.
