Is (-5,17) a solution of y=3x+2?
Answer:
no
Step-by-step explanation:
When solving this equation you would substitute the x coordinate for x and the y coordinate for y:
[tex]17=(3*-5)+2[/tex]
Then multiply -5 and 3:
[tex]17=-15+2[/tex]
Then, add it out and you will come to the conclusion that it equals negative 13 not 17. The correct answer would be (5,17).

The table below shows X and Y values for the equation Y = X + 13
What is Y when X = 17?
Answer:
[tex]Y=30[/tex]
Step-by-step explanation:
[tex]Y=X+13[/tex]
If X = 17, you have to add that with 13 to get Y.
[tex]17(X)+13=30\\Y=30[/tex]
That is your final answer.

if elizabeth gets $5 per hour for babysitting plus $4 extra for putting the child to bed, write a formula that could be used to amount (A) she makes after working h hours
Answer: 5h+4=A
Step-by-step explanation:
She gets five dollars an hour so for one hour she gets five dollars, for two hours she gets 2 times 5 dollars (10 dollars), for three hours she gets 3 times 5 dollars (15 dollars) etc...
Now replace the 1,2,3... with the variable representing the hour. In this case it would be h. So 5h=five dollars per hour. Because you only put the kid to bed once, you add four at the end

Answer:
-10 or 25 (read my explanation)
Step-by-step explanation:
(-5)2
-5*2=-10
(Unless the 2 is supposed to be an exponent)
If it is supposed to be an exponent the answer is 25
(-5)^2
25
[tex]\huge\boxed{Hi\;there!}[/tex]
(-5)2 means negative five times 2.
The answer is -10.
Remember, if we multiply a negative times a positive, we get a negative number.

A study showed that the ratio of the number of people who get their news from print sources to the number of people who get their news from social media sources is 3:7. Based on the ratio, how many people in a town of 900 people get their news from social media sources?
Two classmates solved this problem and their work is shown below. Which classmate solved the problem correctly? Explain the error in the classmate who solved it incorrectly.
Answer:
270 = number who get news from print sources
630 = number who get news from social media
Step-by-step explanation:
Let 3x = number who get news from print sources
and 7x = number who get news from social media
Then 3x + 7x = 900
10x = 900
x = 90
3x = 3(90) = 270 = number who get news from print sources
7x = 7(90) = 630 = number who get news from social media
Check: 270/630 = 3/7 and 270 + 630 = 900

Jesse has 158 quarters and nickels. The value of the collection is $19.10. How many of each coin does she have?
Answer:
102 nickels and 56 quarters
Step-by-step explanation:
Since the total amount of coins is 158, then...
q+n=158
Since the total amount of money is $19.10, and a quarter is 25 cents and a nickel is 5 cents, then...
0.25q+0.05n=19.10
Now that we have 2 equations and 2 variables, we can solve for this equation by solving the first equation for q and plugging it into the second equation.
q+n=158,
q=158-n
Plug into the other equation,
0.25(158-n)+0.05n=19.10
and solve for n
39.5-0.25n+0.05n=19.10
39.5-0.2n=19.10
-0.2n=-20.4
n=102
there are 102 nickels.
Now solve for quarters.
q+n=158
q+102=158
q=158-102
q=56
Find the missing value to the nearest hundredth sin= 7/25
Answer:
16.26
Step-by-step explanation:
I am not completely sure what the problem is asking, but I believe that you are just supposed to take the inverse of sine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then sine. You use the inverse of sine when two sides are given, but you are not given the angle.
It should look like:
[tex]sin^{-1}(\frac{7}{25})[/tex], which is approximately 16.26.
Hopefully this is right, if not, please let me know. Good luck.

2. 72.8 cm
3. 28.35 Inches
4. I think its the 11, and the area is 49.14 inches
Area of rectangle = base × height
Area of parallelogram = base × height
1.

The measurement that is unnecessary is 11.7 inches because only base and height is required to find the area.
A family wants to rent a car to go on vacation. Company A charges $45.50 and 11c per mile. Company B charges $60.50 and 13c per mile. How much does Company B charge for x miles than company A?
Answer: Company B charges $(15.5+0.12x) more for x miles than company A.
Step-by-step explanation:
Let x = Number of miles.
Total charge = Flat charge + (charge per mile) x (Number of miles)
Given:
For Company A ,
Flat charge= $45
Charge per mile = 11 cents = 0.11 [ 1 dollar = 100 cents i.e. 1 cent = 0.01 dollar]
Total charge = 45+0.01x
For Company B,
Flat charge= $60.50
Charge per mile = 13 cents = 0.13
Total charge = 60.50+0.13x
Difference in charge = Charge for company B - Charge for company A
= 60.50+0.13x-(45+0.01x)
= 15.5+0.12x
Hence, Company B charges $(15.5+0.12x) more for x miles than company A.

A solid cone of height 12cm and radius 9cm is recast into a solid sphere. Calculate the surface area of the sphere
Answer:
1017.8
Step-by-step explanation:
this is the formula 4πr2
hope this helps: )
Answer:
Step-by-step explanation:
Volume of cone = π9²⋅12/3 = 324π cm³
volume of sphere = 4πr³/3 = 324π
r = ∛243
surface area of sphere = 4πr² ≈ 155.8π

En una zona industrial se encuentran dos contenedores: en uno hay 198 litros de jugo de arándanos y en el otro hay 144 litros . Para su transporte se requiere guardar el jugo en el menor número de envases iguales. ¿Cuál debe ser la capacidad máxima de estos envases para que no sobre jugo?
Answer:
2 envases iguales de 171 litros
Step-by-step explanation:
Para calcular esto, primero necesitamos sumar los dos contenedores y cuantos litros de jugo tienen cada uno.
198 + 144 = 342 litros.
Ahora tenemos que calcular el numero minimo de envases. Si ya sabemos que es un numero par entonces lo podemos dividir en dos envases iguales sin que sobre...
342 / 2 = 171 litros
Finalmente, podemos ver que podemos dividir el jugo en 2 envases iguales de 171 litros
