Name the constant of variation for y equals 1/4x then find the slope of the (0,0) and (4,1)... please
Answers
Answer:
Constant of variation: 1/4
Slope of the line: 1/4
Step-by-step explanation:
The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".
Which ratio is the simplest form of 68:84?
A 2:3
17:21
34:42
D 21:17
Answers
Answer:
17:21
Step-by-step explanation:
The ratio 68:84 in its simpliest form is;
68:84 (Since it can divided by 2 perfectly);
34:42 (We also divide this by 2 )
17:21
17:21 is the final answer and it can be divide any further. Since 17 is a prime number, it can't be divided and also 21 can be divided by 3 but 17 can't be divided by 3 so we leave the final answer like that.
Your parents gave you $20 to spend at the book fair. You are getting the new Diary of the Wimpy kid book that costs $8.99/ If pencils and erasers cost $0.79 each, what is the maximum you can buy with the money provided?
Answers
Answer:
You can buy a maximum of 13 erasers/pencils.
Step-by-step explanation:
Your total is 20 dollars. The book cost 8.99, so you take away that amount from 20, getting you 11.01. You have $11.01 left. Then you divide your total (11.01) by the price of each eraser (0.79). This gets you 13.9367088608. Since thats not an even number, you have to round down because you don't want a broken pencil?eraser.

What is the total cost for x months?c.Graph the cost of the cell phone plan over a period of two years using month as the units of time be sure to label your axes and scale them by labeling each grid line with a number.d.Is there a portions relationship between time and the cost of the cell phone plan.e. Draw a line a parallel to the line you graphed that goes through the point(0,350) suppose that this line represents the pricing plan for another company.What is the startup fee and monthly cost for this plan?
Answers
Answer:
a. $250
b. The total cost for x month is $200 + $50 × x
c. Please see the attached graph
d. Yes, there is a proportional relationship between time and the cost of the cell phone plan
e. $350
Step-by-step explanation:
The given parameters are;
The costs to start on the cell phone cell = $200
The charge each month = $50
a. The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge = $200 + $50 = $250
b. The total cost for x month, c = $200 + $50 × x
c. Please see the attached graph
d. Yes, there is a proportional relationship between time and the cost of the cell phone plan
e. The line parallel to the line graphed that goes to the point (0, 350), is given as follows;
y = m·x + c
Where;
m = 50
y - 350 = 50 × (x - 0)
y = 50·x + 350
The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;
c = 50 × 0 + 350 = 350
The startup fee for the pricing plan = $350.
The startup fee and monthly cost for this plan according to the question is :
Part a:
The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge
Total Cost = $200 + $50 Total Cost = $250 The total cost to use the cell phone plan for 1 month is $250.Part b:
The total cost for x month, c = $200 + $50 × x The total cost for x month is $200 + $50 × x c.Please see the attached graph
Part c:
Yes, there is a proportional relationship between time and the cost of the cell phone plan .
Part e:
The line parallel to the line graphed that goes to the point (0, 350), is given as follows;
y = m·x + c
Where;
m = 50 y - 350 = 50 × (x - 0) y = 50·x + 350
The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;
c = 50 × 0 + 350 = 350
Yes, there is a proportional relationship between time and the cost of the cell phone plan e. $350
The given parameters are; The costs to start on the cell phone cell = $200 The charge each month = $50
The startup fee for the pricing plan = $350.

Answers
Answer:
A partir del problemas vamos a crear una ecuación donde X es una docena de huevos y Y una libra de mantequilla
entonces: 4 docenas de huevos y 3 libras de mantequilla es igual a 14.100
en mi primera ecuación seria: 4X + 3Y = 14.100
ahora haremos la segunda ecuacion: tres docenas y 1 libra de mantequilla
en mi segunda ecuación seria: 3X + 1Y = 8.700 el plan es sumar las dos ecuaciones pero yo quiero que al sumarlas la variable "Y" desaparezca así que mi segunda ecuación la voy a multiplicar pór (-3) quedándome todo así:
primera ecuación: 4X + 3Y = 14.100
segunda ecuacion multiplicada por -3: -9X - 3Y = -26.1
al sumarlas obtengo como resultado: -5X = -12
resolviendo esa ecuacion obtengo que X=
X=2.4
luego reemplazas X en la primera ecuación: 4X + 3Y = 14.100
reemplazando seria: 4 x (2.4) + 3Y =14.100
9.6 + 3Y = 14.1000
3Y= 14.100 - 9.6
Y=
Y=1.5
entonces concluimos que la docena de huevos cuesta 2.4 $ y la libra de mantequilla 1.5 $

What is 35a + 14 = 1
Answers
Answer:
a = -13/35
Step-by-step explanation:
35a + 14 = 1
(given)
_________
35a + 14 = 1
- 14 -14
(subtraction property of equality)
(subtract 14 from both sides to isolate the 35a term)
_________
35a = -13
÷35 ÷35
(division property of equality)
(divide by 35 on both sides to remove the coefficient of 35 in 35a)
_________
a = -13/35
35a+14=1
35a+14 - 14 = 1 - 14
35a= -13
35a= -13
35a = -13
35 35
a= -13/35
finding the x- and y- intercepts of 50x-5y =25
Answers
Answer:
y = 5.00000
x = 0.50000
50x - 5y = 25
50x - 5(0)= 25
50x = 25
x = 0.5
y - intercept is the value of y when x equals zero
50x - 5y = 25
50(0)- 5y = 25
- 5y = 25
y = -5

2 x ? = 7 1/2 and ? x 2 = 7 1/2
Step-by-step explanation:
This is the answer because it didn't show the answer so all you have to figure out is the multiplication problem that goes with the division problem. So 2 x ? = 7 1/2 and ? x 2 = 7 1/2 you don't have to include the answer all you have to include is where the answer will do if you DID have the answer. These two are correct because the multiplication number can go in any order.
I know this might not be the best step-by-step explanation ever but I truly tried but the answer is correct.
