correct answer is d i think so

use the matrix tool to solve the system of equations enter the answer as an ordered pair. 8x+5y=9 -x+y=7

### Answers

**Answer:**

**x = -44/13**

**y = -65/13**

**Step-by-step explanation:**

Using matrix form means using the crammers rule

The matrix form of the expression is written as;

[tex]\left[\begin{array}{ccc}8&5\\-1&1\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}9\\7\\\end{array}\right][/tex]

AX = B

taking the determinant of A;

|A| = 8(1) - 5(-1)

|A| = 8 + 5

|A| = 13

After replacing the first row with the column matrix;

[tex]A_x =\left[\begin{array}{ccc}9&5\\7&-1\\\end{array}\right][/tex]

|Ax| = 9(-1)-5(7)

||Ax| = -9 - 35

|Ax| = -44

x = |Ax|/|A|

x = -44/13

similarly for y

[tex]A_x =\left[\begin{array}{ccc}8&9\\-1&7\\\end{array}\right][/tex]

|Ay| = 8(7)+9

|Ay| = 56+9

|Ay| = 65

y = |Ay|/|A|

**y = -65/13**

solve: 2x+3y=12 6x-y=4

What is the maximum height of of Anna's golf ball? The equation is y=x−0.04x2.

### Answers

**Given:**

The height of a golf ball is represented by the equation:

[tex]y=x-0.04x^2[/tex]

**To find:**

The maximum height of of Anna's golf ball.

**Solution:**

We have,

[tex]y=x-0.04x^2[/tex]

Differentiate with respect to x.

[tex]y'=1-0.04(2x)[/tex]

[tex]y'=1-0.08x[/tex]

For critical values, [tex]y'=0[/tex].

[tex]1-0.08x=0[/tex]

[tex]-0.08x=-1[/tex]

[tex]x=\dfrac{-1}{-0.08}[/tex]

[tex]x=12.5[/tex]

Differentiate y' with respect to x.

[tex]y''=(0)-0.08(1)[/tex]

[tex]y''=-0.08[/tex]

Since double derivative is negative, the function is maximum at [tex]x=12.5[/tex].

Substitute [tex]x=12.5[/tex] in the given equation to get the maximum height.

[tex]y=(12.5)-0.04(12.5)^2[/tex]

[tex]y=12.5-0.04(156.25)[/tex]

[tex]y=12.5-6.25[/tex]

[tex]y=6.25[/tex]

**Therefore, the maximum height of of Anna's golf ball is 6.25 units.**

The mean weight of nine players on a baseball team is 71 pounds. The weights of the nine baseball players are: { 64, 75, 68, 72, 80, 76, 68, 74, n }. The equation below can be used to find the weight of the ninth player. Which of the values listed { 71, 73, 62, 82, 64 } can be the weight of the ninth baseball player? Explain how you found your answer.

### Answers

**Answer:**

**Step-by-step explanation**

**The mean is equal to the total weight of the players/the number of players**

So, 64, 75, 68, 72, 80, 76, 68, 74, n/ 9=71

Once you add the values in the numerator, you would get 577+n/9=71

n= 71 * 9=639

639-577=62

So, the weight of the 9th player would be 62 pounds.

In a rectangle, the length is 5 more than three times the width. The perimeter is 250cm. Determine the length of each side.

### Answers

**Answer:**

l = 95 cm

w = 30 cm

**Step-by-step explanation:**

w = width

5+3w = length

P = 2l + 2w

250 = 2(5+3w) + 2w

250 = 10 + 6w + 2w

240 = 8w

w = 30

5 + 3(30) = length

l = 95

You earn $30K at your job, and put 20% aside each month into a retirement fund. Your

company is super cool and matches your contributions. For every dollar you put into

your IRA, your employer also puts in a dollar.

How much will you have contributed to your retirement account by the end of the year?

### Answers

Answer:

$12,000

Step-by-step explanation:

20% as a decimal is 0.20

30,000 x 0.20 = 6,000

If the employer matches that, the amount deposited is double.

6,000 x 2 = 12,000

That is probably the answer they want. Technically the question asks way *you* will have contributed, which is $6,000, but I don’t think they’re trying to make this a trick question. I would go with 12k
