One large jar and five small jars can hold 26 ounces of jam. One large jar minus one small jar can hold 2 ounces of jam. Use the

given matrix equation to solve for the number of ounces of jam that each jar can hold. Explain the steps that you took to solve this problem.
A matrix with 2 rows and 2 columns, where row 1 is 1 and 5 and row 2 is 1 and negative 1, is multiplied by matrix with 2 rows and 1 column, where row 1 is l and row 2 is s, equals a matrix with 2 rows and 1 column, where row 1 is 26 and row 2 is 2.

Using a system of equations, it is found that one large jar holds 6 ounces and one small jar holds 4 ounces.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable l: Weight that a large jar holds.
  • Variable s: Weight that a small jar holds.

One large jar and five small jars can hold 26 ounces of jam, hence:

l + 5s = 26, which is the first equation in matrix form.

Then:

l = 26 - 5s.

One large jar minus one small jar can hold 2 ounces of jam, hence:

l - s = 2, which is the second equation in matrix form:

Then:

l = 2 + s = 26 - 5s

2 + s = 26 - 5s

6s = 24

s = 4.

l = 26 - 5s = 6.

In a bag, there are red and blue cubes in the ratio 4 : 7
MariettaO [177]

The number of the blue cubes is 35 and the number of the red cubes is 20.

<h3>What is the ratio?</h3>

The ratio is defined as the representation of the one number with respect to the other number. or one number is how many times the other number.

Given that:-

  • In a bag, there are red and blue cubes in the ratio of 4: 7
  • I add 10 more red cubes to the bag. Now there are red and blue cubes in the ratio of 6: 7

The number of the blue cubes are calculated as:-

The two equations will be formed by the given data in the question.

\dfrac{r}{b}=\dfrac{4}{7}

7r = 4b

\dfrac{r+10}{b}=\dfrac{6}{7}

7r + 70 = 6b

Solving the above equation we will get the value of b.

4b + 70 = 6b

6b - 4b = 70

2b = 70

b = 35

7r = 4b

7r = 4 x 35

r = 20

Therefore the number of the blue cubes is 35 and the number of the red cubes is 20.

The vertex of the graph of a quadratic function is (2.-1) and they intercept is (0,7). Which of the following is the equation of
Sophie [7]
\text{The vertex formula:}\\\\f(x)=a(x-h)^2+k\\\\(h;\ k)-\text{the coordinates of the vertex}
\text{We have:}\\\\\text{the vertex}\ (2;\ -1)\to h=2;\ k=-1\\\\\text{y-intercept}\ (0;\ 7)\to f(0)=7
\text{substitute:}\\\\f(x)=a(x-2)^2-1\\\f(0)=7\to a(0-2)^2-1=7\ \ \ |+1\\\\4a=8\ \ \ |:4\\\\a=2
\text{Answer in the vertex form:}\\\\f(x)=2(x-2)^2-1\\\\\text{Answer in the standard form:}\\\\f(x)=2x^2-8x+7

Anyone know this answer?
frez [133]

Answer:

For number 1 the answer should be independent.

For number 2 the answer should be independent

And number 3 should also be independent

Step-by-step explanation:

My explanation is that they are all independent because you aren't depending on someone to help you do these things, therefore, independent.

I hope this helps :)
