how would I solve the system x + 2y = 13, -x + y = 5 when using elimination
Answers
Answer:
x + 2y = 13}(add the both eqns)
-x + y = 5}
x +(-x) = 0
2y + y = 3y
13 + 5 = 18
then,
3y = 18
y = 6
from
x + 2y = 13
x = 13 - 2(6)
x = 1

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.

A bag containing food has mass 3.813 kg. When the bag is empty its mass is 257 g. Find in kilograms the mass of the fruit
Answers
Answer:
I think it is 0.257 kg
Step-by-step explanation:
To change units from the gram to kilogram, you need to divide by 1000, because 1kg=1000g:
257÷1000= 0.257 Kg
The mass of the fruits in kilogram (kg) is 3.556 kg
Given:
Mass of the bag containing fruits = 3.813 kg
Mass of the empty bag = 257 g
convert
257 g to kg
257 g = 0.257 kg
Mass of the bc fruits = Mass of the bag containing fruits - Mass of the empty bag
= 3.813 kg - 0.257 kg
= 3.556 kg
Therefore, the mass of the fruits in kilogram is 3.556 kg

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 $

A tire manufacturer knows that 5% of tires contain a defect, and the presence of a defect is independent from tire to tire.
What is the probability that if 5 tires are inspected, exactly 1 has a defect?
Round to 3 decimal places.
Answers
Answer:
the answer is 0.204
Step-by-step explanation:
The probability that if 5 tires are inspected, exactly 1 has a defect is 0.204
How to determine the probability?The probability that a tire is defect is given as:
p = 5%
The required probability is then calculated using:
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]
Where:
n = 5 --- number of tires
x = 1 ---number of tires with defect
So, we have:'
[tex]P(1) = ^5C_1 * (5\%)^1 * (1 - 5\%)^{5 - 1}[/tex]
This gives
[tex]P(1) = 5 * (5\%) * (1 - 5\%)^4[/tex]
Evaluate the product
P(1) = 0.204
Hence, the probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

Graph this system of equations.
1.15x + 0.65y = 8.90
x − 3y = -15
Answers
Answer:
We have the equations:
1.15x + 0.65y = 8.90
and
x − 3y = -15
First, let's write them in the slope-intercept form:
The first one will be:
y = -(1.15/0.65)*x + 8.90/0.65
The second:
y = (1/3)*x + 15/3 = (1/3)*x + 5.
then our system is:
y = -(1.15/0.65)*x + 8.90/0.65
y = (1/3)*x + 5.
To graph each line, you can just evaluate the line in two points (for x = 0 and x = 1, for example) and then locate those points in the coordinate axis, and then draw a line that connects them.
For example with the second line:
y(0) = (1/3)*0 + 5 = 5
then we have the point (0,5)
and
y(3) = (1/3)*3 + 5 = 8
Then we have the point (3,8)
With the first equation may be a little harder, as the coefficients are not whole numbers, we can rewrite it as:
y = (1.15/0.65)*x + 8.90/0.65 = (115/65)*x + (890/65)
Where i multiplied and divided by 100 the numerators and denominators in the right side, so now is easier to work with it.
The points you can use are:
y(0) = (115/65)*0 + (890/65) = 13.7
the point is (0, 13.7)
and:
y(1) = (115/65)*1 + (890/65) = 15.5
The point is (1, 15.5)
Below you can see the graphs of both functions:
blue: y = -(1.15/0.65)*x + 8.90/0.65
red: y = (1/3)*x + 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

Answers
Answer:
Nelly will need $16.43.
Step-by-step explanation:
First, you want to find out how much 1 book costs.
Take 10.95 and divide it by 4.
10.95/4=$2.73
Take the 2.73 and multiply it by 6.
6x2.73=16.425
=$16.43
Answer:
16.43 i think

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
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".
