Answer:
7 and -7
Step-by-step explanation:
Correct question
Which shows all the values of x that make the rational expression 2x^2-72/5x^2-245 undefined
For the expression to be undefined, the denominator must be equal to zero
Hence 5x² - 245 =0
Add 245 to both sides
5x²-245+245 = 0+245
5x² = 245
x² = 245/5
x² = 49
x = ±√49
x =7 and -7
Hence the values of x that will make the function undefined are 7 and -7
Roberto has a certain number of songs on his MP3 player. Each week, he plans to add 4 more songs. After 5 weeks, he had 40 songs on his MP3 player. Which statement is true?
A. Roberto adds 5 songs on his MP3 player per week.
B. Roberto adds 10 songs on his MP3 player per week.
C. The initial number of songs on Roberto’s MP3 player is 10.
D. The initial number of songs on Roberto’s MP3 player is 20.
Please and the work for it too
Answer:
the answer is D. because 5×4=20, he had a total of 40 at the end so you subtract 20 from 40 and his initial amount of songs was 20.

Explanation:
y = x - 4
y = 6x - 10
-----------------------
x - 4 = 6x - 10
-4 = 6x - x - 10
10 - 4 = 5x
x = 1.2
-----------------------
y = x - 4
y = 1.2 - 4
y = -2.8

how much water must be added to a 9-liter solution that contains 3% extract on baneberry to get a solution that contains 2% extract of baneberry
Answer:
Amount water added = 4.5 L
Step-by-step explanation:
Given:
Amount of solution = 9 L
Amount of bane-berry = 3% of 9 L = 0.27 L
Computation:
Assume;
Amount water added = x L
Total solution = 9+x L
New percentage of bane-berry = 0.27x100/(9+x)
2 = 0.27*100/(9+x)
x = 4.5 L
Amount water added = 4.5 L
Anna also wants to travel after graduation but she isn’t working while in school so she won’t be able to put money aside regularly. However, her grandmother gave her the generous gift of $2500 for her birthday and suggested she invest it in a GIC because it’s low risk. She shopped around and found a 4 year GIC investment that earns 2.8% interest annually. How much will Anna have at the end of her four year investment?
Answer:
She will have $2792 at the end of her four year investment
Step-by-step explanation:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Gift of $2500:
This means that [tex]P = 2500[/tex]
She shopped around and found a 4 year GIC investment that earns 2.8% interest annually.
This means that [tex]t = 4, r = 0.028, n = 1[/tex].
How much will Anna have at the end of her four year investment?
This is A(4). So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(4) = 2500(1 + 0.028)^{4} = 2792[/tex]
She will have $2792 at the end of her four year investment

Find the length of BC, in simplest radical form.
9514 1404 393
Answer:
BC = 16 +12√3
Step-by-step explanation:
In the attached, we see that ∆ABE is a 30°-60°-90° triangle with AB the short side and BE the hypotenuse. Then BE = 2·AB = 12√3.
EC is the side opposite AD in parallelogram ADCE, so is the same length, 16.
The length BC is ...
BC = EC +BE
BC = 16 +12√3

What is Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
cost of gas with tax is $3.81 per gallon
But gas should be less than 14 gallons and not more than 8 gallons.
So,
=3.81×8
=30.48
3.81×14
=53.34
Hence, the range is 30.48 to 53.34,

Step-by-step explanation:
Maybe you're trying to solve ...
5x - 18 ≤ -8
As with any 2-step equation, add the opposite of the constant that is on the same sides as the variable term.
5x -18 +18 ≤ -8 +18
5x ≤ 10 . . . . . . . . . . . simplify
Now, divide both sides by the coefficient of the variable.
5x/5 ≤ 10/5
