PLEASE HELP!!!!!!!!!!!!!!!!! | For what values of y does the following equation have no solutions for x? | xy + 5y + 4x + 20=1
Answer:
y = -4
Step-by-step explanation:
We can solve for x to see.
x(y+4) +5y +20 = 1
x(y +4) = -19 -5y . . . . . subtract 5y+20
x = (-19 -5y)/(y +4)
x is undefined (no solution) for y = -4.
Answer:
y = -4
Step-by-step explanation:
If we look at xy + 5y, we see that both terms share a factor of y. This gives us
y(x + 5) + 4x + 20 = 1
Similarly, 4x and 20 share a factor of 4, giving us
y(x + 5) + 4(x + 5) = 1
Now we see that these two terms share a factor of x + 5, so factoring gives us
(y + 4)(x + 5) = 1
Dividing both sides by y+4 gives us
x + 5 = 1/(y + 4)
Finally, we subtract both sides by 5 to get
x = 1/(y + 4) - 5
Thus, since we can not have a 0 in the denominator, we see that if y = -4 then x will have no solution. For any other value of y, we can find the solution for x using this equation.
this is a segment addition practice. can someone please help me find the length indicated?
Answer:
3
Step-by-step explanation:
Points C, D, and E are collinear.
Segment CD = 8
Segment CE = 11
Segment DE = ?
According to the segment addition postulate:
[tex] CD + DE = CE [/tex]
[tex] 8 + DE = 11 [/tex] (substitution)
Subtract 8 from both sides
[tex] 8 + DE - 8 = 11 - 8 [/tex]

A pendulum swinging through a central angle of 108° completes an arc of length 24 cm. What is the length of the
pendulum? Round to the nearest hundredth.
Answer:
Yes! I was looking to refresh my geometry skill!
Step-by-step explanation:
So, a 108* arc is 24 cm. How to solve it?
First, we need to find the Circumference, or perimeter of the circle. (That the swinging pendulum makes.
Second, use that in the formula for circumference, and find the radius.
Third, done! So, let's get to it!
All we have to do to find the circumference is divide 24 by 108, then multiply that by 360*(because a circle is 360*).
[tex]24/108*360=80[/tex]
So, our circumference is 80cm. Nice! Just need to input that into the circumference formula.
[tex]80=2\pi *r\\[/tex]
Now, to solve...
[tex]40=\pi *r\\40/\pi =r[/tex]
This rounds to about 12.73 cm.
Hope this helps!

Rhonda had $300 to buy supplies for the animal shelter. She bought 8 bags of dog food and 11 leashes. Each bag of food cost $25.19, and each leash cost $4.65. How much money did Rhonda have left after her purchases? $11.65 $14.29 $22.91 $47.33
Hey there! I'm happy to help!
We have 8 bags of dog food and each costs $25.19
8(25.19)=201.52
And we have 11 leashes each costing $4.65.
11(4.65)=51.15
We add these totals up.
201.52+51.15=252.67
We subtract this from 300 to see how much is left.
300-252.67=47.33
Rhonda had $47.33 left after her purchases.
Have a wonderful day! :D
Answer:
$47.33
Step-by-step explanation:
she bought 8 bags of dog food so: 8 x 25.19 = 201.52
she bought 11 leashes so: 4.65 x 11 = 51.15
201.52 + 51.15 = 252.67
300 - 252.67 = 47.33

1/3 is .333333.....
6/12 is .5, doesn’t repeat.
3/4 is .75, also doesn’t repeat.

What is another name for a fraction that as a numerator and a denominator that have the same integer? Your answer This is a required question
Answer:
I think it would be considered 1
Step-by-step explanation:
If you have a fraction that has the same integer for the numerator and denominator, that fraction would equal to 1 because the fraction is completed. As an example, 5/5 is equal to one because there is 5 pieces of the fraction needed to complete it, and there's and available 5. Meaning that there's 5 out of 5 pieces needed to create a whole number which would be 1.
Decimal form: .2 + .2 + .2 + .2 + .2 = 1.0
Written form: 1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 or 1

Jennifer is buying a plane ticket to travel abroad. The price of the plane ticket is P dollars, and she has to pay the additional 8% airport
security tax
Match the expressions to their correct meaning for Jennifer.
Answer:
The price of the ticket before tax - P
The amount of tax Jennifer pays- 0.08P
Jennifer's total amount for the ticket- P + 0.08P
Step-by-step explanation:
The price of the plane ticket is P dollars, before airport security tax. Here P is an independent variable.
An airport security tax of 8% is applied to the price of a plane ticket. So, the amount of airport security tax that Jennifer pays is 8% of the cost of her plane ticket, or 0.08P.
To find Jennifer's total amount for the plane ticket, add the price of the ticket before airport security tax and the amount of airport security tax Jennifer pays. So, the total amount of the plane ticket is P + 0.08P.
The table below shows the expressions matched to their meanings.
An expression is defined as a set of numbers, variables, and mathematical operations. Jennifer's total amount for the ticket is P+0.08P.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given that Jennifer is buying a plane ticket to travel abroad. The price of the plane ticket is P dollars, and she has to pay the additional 8% airport security tax. Therefore, we can write the expressions as,
The price of the ticket before tax → P
The amount of tax Jennifer pays → 8% of P = 0.08p
Jennifer's total amount for the ticket → Price of ticket + Tax = P + 0.08P
Hence, Jennifer's total amount for the ticket is P+0.08P.

Answer:
x + 4 = 9 + 2x - 15

A rectangular box with a depth of 10 inches and a square base is to be manufactured by the Bold Box Company. The top of the box costs $1.20 per square inch, the bottom costs $.95 per square inch and the sides cost $.75 per square inch. Express the cost of manufacturing this box as a function of length.
Answer:
The cost function of manufacturing this box is:
[tex]C_{T} = 2.15\cdot x^{2}+30\cdot x[/tex], where [tex]x[/tex] is the length of the box, measured in US dollars.
Step-by-step explanation:
From the statement we know that:
1) The box has a square base ([tex]w = l = x[/tex]).
2) The box has a depth of 10 inches ([tex]h = 10\,in[/tex]).
3) The cost of manufacturing the top of the box is $ 1.20 per square inch.
4) The cost of manufacturing the bottom of the box is $ 0.95 per square inch.
5) The cost of manufacturing each side of the box is $ 0.75 per square inch.
The total cost of manufacturing the box is:
[tex]C_{T} =C_{bottom} + C_{top} + 4\cdot C_{side}[/tex]
Where:
[tex]C_{bottom}[/tex] - Cost of the bottom of the box, measured in US dollars.
[tex]C_{top}[/tex] - Cost of the top of the box, measured in US dollars.
[tex]C_{side}[/tex] - Cost of the side of the box, measured in US dollars.
Dimensionally, cost equals unit cost, measured in US dollars by square inch, multiplied by surface area, measured in square inches. Now, the expression is expanded:
[tex]C_{T} = c_{bottom}\cdot x^{2}+c_{top}\cdot x^{2}+4\cdot c_{side}\cdot h\cdot x[/tex]
[tex]C_{T} =(c_{bottom}+c_{top})\cdot x^{2}+4\cdot c_{side}\cdot h \cdot x[/tex]
If we know that [tex]c_{bottom} = \$\,0.95\,in^{-2}[/tex], [tex]c_{top} = \$\,1.20\,in^{-2}[/tex], [tex]c_{side} = \$\,0.75\,in^{-2}[/tex] and [tex]h = 10\,in[/tex], the cost function of manufacturing this box is:
[tex]C_{T} = 2.15\cdot x^{2}+30\cdot x[/tex], where [tex]x[/tex] is the length of the box, measured in US dollars.

substitute the values with the ones from the 2 points
-13-(-5)= -8
-19-(-8)=-11
you then divide -8/-11
and you get 8/11

Which ratio is greater than 5/8 ? A. 12/24 B. 3/4 C. 15/24 D. 4/12
B is the 3/4 = .75 and 5/8 = .625
The sum of two numbers is 50. The first number is 18 less than the 2nd number. What are the
2 numbers?
Answer:
2y + 2 + y = 50 (combine like terms)
3y + 2 = 50
3y = 50 - 2
3y = 48
y = 16
Substitute 16 for y in either equation 1 or 2 and solve for x (I chose equation 1):
x + 16 = 50
x = 50 - 16
x = 34

Amy invested in three companies: 1400 dollars for Apple, 1900 dollars for Google and 1700 dollars for Starbucks. Over the course of one year, she found that Apple went down 4 percent, Google went up 5 percent and Starbucks went up 3 percent. What is the average change in her portfolio?
Loss in apple [tex]=1400\times \dfrac{4}{100}= 56[/tex]
Present value = 1400 - 56 = $1344 .
Loss in google [tex]= 1900\times \dfrac{5}{100}=95[/tex]
Present value = 1900 + 95 = $1995 .
Loss in Starbucks [tex]=1700\times \dfrac{3}{100}=51[/tex]
Present value = 1700 + 51 = $1751 .
Total investment , T = 1400 + 1900 + 1700 = $5000 .
Gain , G = 56 + 95 + 51 = $202 .
% increase [tex]=\dfrac{202}{5000}\times 100 = 4.04 \%[/tex]
Hence , this is the required solution .
