Answers

Answer:

  d  2

Step-by-step explanation:

The system of equations can be written in augmented matrix form as ...

  [tex]\displaystyle\left[\begin{array}{cc|c}-\frac{1}{2}&3&-4\\-1&-1&-1\end{array}\right][/tex]

The value of x found by Cramer's rule is the ratio of two determinants. The numerator is the coefficient matrix with the x-column replaced by the constant column. The denominator is the coefficient matrix.

  [tex]\displaystyle x=\frac{\left|\begin{array}{cc}-4&3\\-1&-1\end{array}\right| }{\left|\begin{array}{cc}-\frac{1}{2}&3\\-1&-1\end{array}\right|}=\frac{(-4)(-1)-(-1)(3)}{(-\frac{1}{2})(-1)-(-1)(3)}=\frac{4+3}{\frac{1}{2}+3}\\\\\boxed{x=2}[/tex]

Using the Cramer's rule, the value of x in the system of equation is 2

How to solve for x?

The system of equation is given as:

-1/2x + 3y = -4

-x - y = -1

Represent the above equation as a matrix

[tex]\left[\begin{array}{cc}-1/2&3\\-1&-1\end{array}\right] \left[\begin{array}{c}-4&-1\end{array}\right][/tex]

Start by calculating the determinant of the matrix

|A| = -1/2 * -1 - 3 * -1

Evaluate

|A| = 7/2

To calculate x, we replace the first column by the last.

So, we have:

[tex]\left[\begin{array}{cc}-4&3\\-1&-1\end{array}\right][/tex]

Next, calculate the determinant of the matrix

|x| = -4 * -1 - 3 * -1

|x| = 7

The value of x is then calculated as:

x = |x|/|A|

This gives

x = 7 ÷ 7/2

Evaluate

x = 2

Hence, the value of x is 2

Answers

Answer: x > 2.5

Step-by-step explanation:

Since Mrs Gallegos burns 236 calories riding her bike each hour and she wants to burn more than 590 calories riding her bike at the same rate, the inequality that will represent the number of hours that she will use will be:

x > 590/236

x > 2.5

She must ride the bike for more than 2 1/2 hours to burn more than 590 calories.

If a rectangle is 19.6 m on one side and 24 m on the other side what would be the perimeter and area

Answers

Answer:

Perimeter = 87.2 m

Area = 470.4 square meters

Step-by-step explanation:

Formula to get the perimeter of a rectangle = 2(length + width)

                                                                         = 2(19.6 + 24)

                                                                         = 2(43.6)

                                                                         = 87.2 m

Similarly by using formula to get the area of the rectangle,

Area = Length × Width

        = 19.6 × 24

        = 470.4 m²

. 3(a - 2) – 4(2a - 3)

Answers

Answer:

a = 0.5454545455

Step-by-step explanation:

Simplifying

3(a + 2) + 4(2a + -3) = 0

Reorder the terms:

3(2 + a) + 4(2a + -3) = 0

(2 * 3 + a * 3) + 4(2a + -3) = 0

(6 + 3a) + 4(2a + -3) = 0

Reorder the terms:

6 + 3a + 4(-3 + 2a) = 0

6 + 3a + (-3 * 4 + 2a * 4) = 0

6 + 3a + (-12 + 8a) = 0

Reorder the terms:

6 + -12 + 3a + 8a = 0

Combine like terms: 6 + -12 = -6

-6 + 3a + 8a = 0

Combine like terms: 3a + 8a = 11a

-6 + 11a = 0

Solving

-6 + 11a = 0

PLS HURRY I NEED ALL THE STEPS TOO THANK YOU!!!!!

Answers

Answer:

See explanartions below

Step-by-step explanation:

Given the coordinates A(-6,3) B(0,5) C(2,-1)

We first need to get the slope of AB, BC and AC

For AB;

A(-6,3) B(0,5)

Mab = 5-3/0-(-6)

Mab = 2/6

Mab = 1/3

For BC;

B(0,5) C(2,-1)

Mbc = -1-5/2-0

Mbc = -6/2

Mc = -3

For AC:

A(-6,3) C(2,-1)

Mac = -1-3/2-(-6)

MAc = -4/8

Mac = -1/2

Taking the product of Mab and Mbc

Mab * Mbc = 1/3 + -3

Mab * Mbc = -1

Since the product of Mab and Mbc is -1, hence AB abd BC are perpendicular showing that one of the angle of triangle ABC is 90 degrees

A shipping container will be used to transport several 40-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23000 kilograms. Other shipments weighing 7800 kilograms have already been loaded into the container.

Answers

The question is incomplete. The complete question is :

A shipping container will be used to transport several 40-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23000 kilograms. Other shipments weighing 7800 kilograms have already been loaded into the container. Which inequality can be used to determine cc, the greatest number of 80-kilogram crates that can be loaded onto the shipping container?

Solution :

Given data :

Weight of the crate = 40 kg

Greatest weight that the container can load = 23000 kg

Weight of the other shipments on the container = 7800 kg

So the greatest number of 40 kg crates = c

Therefore, the weight of the other shipment + weight of crate x number of crates ≤ greatest weight of the container

7800 + (40 x c) ≤ 23000

7800 + 40c ≤ 23000

40c ≤ 23000 - 7800

40c ≤ 15200

c ≤ 380

Hence, the maximum number of 40 kg crate is 380.

Answer:

2w + 2L is the answer I think, but see the discussion below.

Step-by-step explanation:

There are three possibilities.

One

| = 1

so you get 1 + w + 1 + w = 2 + 2w

Two

l = L

l + w + l + w

So you get 2l + 2w. Since the l is so confusing, I normally use L for l. It's not very pretty but it does work

In this instance, you would get 2L + 2w

Three

| could be an absolute value signal. If that is the case, you should use abs(+w+)

Of the three, I think two is what you intended.

Answer:

a) Only the first one is an identity.

Step-by-step explanation:

1). 8 cos O tan O csc O = 8   simplifies to:

cos O tan O csc O = 1

cos O * (sin O / cos O) * (1 /sin O)

=  cos O sin O / cos O sin O

= 1

So it is identity.

2) 13 sec^2 O/ cos^2 O - tan^2 O / cos^2O

= 13 sec^2 O - tan^2 O / cos^2 O

Now  sec^2 O = 1 + tan^2 O, so we have:

(13( 1 + tan^2 O) - tan^2 O) / cos^2 O

= (12 tan^2 O + 13) / cos^2 O

This is not always = 2 so its not an identity.

Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. She paid a total of $4.25 for these items.

Answer:

Stefanie bought 10 erasers.

Step-by-step explanation:

Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. She paid a total of $4.25 for these items.

Beind "x" be the number of erasers bought, you can express Stepanie's purchases by the equation:

1.75 + 0.25*x = 4.25

Solving:

0.25*x = 4.25 - 1.75

0.25*x = 2.5

x= 2.5÷ 0.25
