How do you use graphs toslove a system of two linear equation

2 answers:

To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect. The two lines intersect in (-3, -4) which is the solution to this system of equations.

Answer:

A system of linear equations is a system made up of two linear equations. To solve the system of equations, you need to find the exact values of x and y that will solve both equations. One good way to do this is to graph each line and see where they intersect.

una familia ha consumido en un dia de verano: dos botellas de litro y medio de agua, 5 botellas de 1/4 de litro de jjugo de appl

aleksandr82 [10.1K]

Answer:

La familia ha bebido en un día de verano $5\,\frac{1}{4}$ litros.

Step-by-step explanation:

Podemos evidenciar que es posible obtener el volumen total de los citados líquidos al sumar el volumen de cada uno. El volumen de cada bebida es igual al producto de su capacidad multiplicada por el número de botellas. Es decir:

$V_{total} = V_{agua} + V_{jugo} + V_{limonada}$

Donde todos los volúmenes se miden en litros.

$V_{total} = (2\,botellas)\times \left(\frac{3}{2} \,\frac{L}{botella} \right)+(5\,botellas)\times \left(\frac{1}{4}\,\frac{L}{botella} \right) + (4\,botellas)\times \left(\frac{1}{4}\,\frac{L}{botella} \right)$

$V_{total} = (2\,botellas)\times \left(\frac{6}{4} \,\frac{L}{botella} \right)+(5\,botellas)\times \left(\frac{1}{4}\,\frac{L}{botella} \right) + (4\,botellas)\times \left(\frac{1}{4}\,\frac{L}{botella} \right)$

$V_{total} = \frac{12}{4}\,L + \frac{5}{4} \,L + \frac{4}{4} \,L$

$V_{total} = \frac{21}{4}\,L$

$V_{total} = \frac{20}{4}\,L + \frac{1}{4}\,L$

$V_{total} = 5\,\frac{1}{4}\,L$

La familia ha bebido en un día de verano $5\,\frac{1}{4}$ litros.

The Acculturation Rating Scale for Mexican Americans (ARSMA) is a psychological testdeveloped to measure the degree of Mexican/S

maria [59]

Answer:

95% confidence interval for the mean ARSMA score for first-generation Mexican Americans

(2.13264 , 2.58736)

Step-by-step explanation:

Step(i):-

Mean of the Population = 3.0

Standard deviation of the Population = 0.8

Given Mean of the sample(x⁻ ) = 2.36

Standard deviation of the sample (S) = 0.8

size of the sample = 50

Level of significance =0.05

Degrees of freedom = n-1 = 50-1 = 49

$t_{\frac{0.05}{2} , 49} = 2.0096$

Step(ii):-

95% confidence interval for the mean ARSMA score for first-generation Mexican Americans

$(x^{-} - t_{(\frac{\alpha }{2},df )} \frac{S}{\sqrt{n} } , (x^{-} +t_{(\frac{\alpha }{2},df )} \frac{S}{\sqrt{n} })$

$(2.36 - 2.0096 \frac{0.8}{\sqrt{50} } , 2.36 +2.0096\frac{0.8}{\sqrt{50} })$

( 2.36 - 0.22736 , 2.36 + 0.22736)

(2.13264 , 2.58736)

Final answer:-

95% confidence interval for the mean ARSMA score for first-generation Mexican Americans

(2.13264 , 2.58736)

Arley’s Bakery makes fat-free cookies that cost $1.50 each. Arley expects 30% of the cookies to fall apart and break. Assume tha

nata0808 [166]

Answer:

Arley should charge $2.25 for each unbroken cookie.

Step-by-step explanation:

1. This problem has a lot of information to take in. To make things easier, it's vital to condense the problem into the most vital information.

Normal Price (x) = $1.50

Markup = %50 (1.5)

Total Price = 1.5x

Note that the amount of cookies produced and the amount charged for the broken cookie was not written in this condensed format.

The question was only: What price should Arley charge for each unbroken cookie?

Neither the cookies produced or the amount charged were part of the question. In this case, the other information is simply there as a filler.

2. With the information given, a simple formula should be created to find the total price.

The formula for this problem is: 1.5x

As stated above, 1.5 represents the 50% markup while the variable (x) represents the normal price.

When 1.5*1.5 is solved, it comes out to $2.25 dollars.

3. The answer is $2.25 dollars for each unbroken cookie.
