need help will give 20 points​

I've arranged the tiles into the correct positions, and wrote in the final result for each x and y.

The basic idea is to divide determinants as the vertical bars indicate (they aren't absolute value bars).

In each denominator is the determinant of the matrix [tex]\begin{bmatrix}2 & 1\\-3 & 4\end{bmatrix}[/tex] which are the coefficients of the left hand side of each original equation given to you.

-------------

The numerators are a slight variation of this matrix. The x determinant will have you replace the first column with 0 & 22 getting [tex]\begin{bmatrix}0 & 1\\22 & 4\end{bmatrix}[/tex] which helps figure out the x solution. The y solution is similar as well, but we replace the y column instead of the x column. So that explains the [tex]\begin{bmatrix}2 & 0\\-3 & 22\end{bmatrix}[/tex]

After you have the proper determinants set up, you just evaluate each determinant using the formula

[tex]\begin{vmatrix}a & b\\ c & d\end{vmatrix} = a*d - b*c[/tex]

and then simplify the results.

Answer:

<-----10%-----1/4------3/4----->

The top left most answer (or A)

Step-by-step explanation:

Let's get all of these terms into the same representation. Meaning let's convert all of the numbers into either fraction or a decimal or percentage.

I find that fraction would be hard and so would percentage, lets try decimal.

1/4 = 0.25 as a decimal. (1/4 = 25/100 = 0.25) 3/4 = 0.75 (same manner as 1/4) Now for 10%. 10% in technical speaking is equal to 10/100 again which means it would be 0.10.

Okay so now they're all decimals let's put them in ascending order!

0.10, 0.25, 0.75. Yay! Now we can see on a number line the order would be

<-----10%-----1/4------3/4----->

I hope this helps!

Step-by-step explanation:

Angles A and B form a linear pair, and are thus supplementary. Therefore, the measure of angle B is 180-105=75 degrees.

Angles E and F are a linear pair, and by the same logic, the measure of angle E is 70 degrees.

Since the sum of the measures of the angles in a triangle is 180 degrees, the measure of angle C is 180-75-70=35 degrees.

Since angles C and D are supplementary, the measure of angle D is 145 degrees.

Answer:

x = 698.771

step-by-step explanation:

apply ln rules

[tex]\sf \rightarrow \dfrac{\ln \left(5^{\dfrac{3}{2}}\right)}{\ln \left(2x\right)}=\dfrac{1}{3}[/tex]

cross multiply

[tex]\sf \rightarrow \ln \left(5^{\dfrac{3}{2}}\right)\cdot \:3=\ln \left(2x\right)\cdot \:1[/tex]

simplify using calculator

[tex]\sf \rightarrow 7.24247 = ln(2x)[/tex]

shift sides

[tex]\sf \rightarrow e^{7.24247 }= 2x[/tex]

divide both sides by 2

[tex]\sf \rightarrow 698.771= x[/tex]

Answer:

[tex]x=698.771[/tex]

Step-by-step explanation:

Answer:

Answer: B. The law says you must write a new living will each time you re admitted to the hospital.

Explanation:

The law does not require that you make a new will whenever you are admitted to the hospital. Any existing will that has fulfilled the provisions of the law are biding unless the person decides to change the will of their own volition.

There is therefore no need to make a new will every time if there is already one in existence and the person is satisfied with it. The Registered Nurse should therefore correct this statement by the Licensed Practical Nurse.

Answer:The total cost is about $124.86

Step-by-step explanation:

The area of the counter top is 16 ft by 3 ft so 16 x 3= 48. The area of the counter top is 48 ft squared.Then you have to convert it to meters squared, 48 x 0.092903 = 4.459244. Then multiply that by 28 to get your answer.4.459244 x 28 = 124.861632. The total cost is about $124.86

Answer:

C. 9 cubic units

Step-by-step explanation:

The formula for the volume of a prism is V=Bh, where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 4 and the width is 3/2 (1 1/2 = 3/2). The area A of a rectangle with length l and width w is A=lw

so the area of the base is 4 x 3/2 which is 6

then we multiply that by the height (3/2) to get 9.

Answer:

The answer is C. $56.00
Hazel earned $56.00 in interest after one year.

Step-by-step explanation:

700 x 0.065 = 45.5

300 x 3.5% =
300 x 0.035 = 10.5

45.5 + 10.5 = 56.00

Answer:

Step-by-step explanation:

p=$1000

rate percent=1.4%

time=one year

then

1.4/100*100=14

The amount of money in his account at the end of one year will be $1014.90. Then the APY for this account to the nearest hundredth of a percent will be 1.41%.

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

[tex]\rm A = P \left (1 + \dfrac{r}{n} \right )^{t \times n}[/tex]

Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.

Rob deposits $1,000 in a savings account at New York State Bank that pays 1.4% interest, compounded monthly.

The amount of money in his account at the end of one year will be

A = 1000 × [1 + 0.014 / 12]¹²

A = 1000 × 1.01409

A = $1014.09

The APY for this account to the nearest hundredth of a percent will be

APY = [(1 + r/n)ⁿ - 1] x 100

APY = [(1 + 0.014 / 12)¹² - 1] x 100

APY = 1.41%

Answer:

Y = 1/2x + 1/2

Step-by-step explanation:

I'm not sure, but I think this is correct

Answer:

Slope intercept form;

y = mx + b

Where y is the independent variable and x is the dependent variable. 'm' represents the slope, and 'b' represents the y - intercept.

If we look at this graph:-

We can see that the line that intersects the y - axis is half of 1 which is 0.5, so that'll be our y-intercept.

It also rises one and goes over two so that'll be our slope.

To double check, we select two fixed points (1,1) and (3,2), we then divide the y-coordinates by the x-coordinates in the following order: (rise/run)

y2(second y-coordinate) - y1(first y-coordinate)

_____________________________________

x2(second x-coordinate) - x1(first x-coordinate)

2 - 1            1

_____ = ______, the slope is 1/2.

3 - 1            2

Now we format it in slope-intercept form:-

y = mx + b

y = 1/2x + 0.5

Where 1/2 is the slope, and 0.5 is the y-intercept

Answer:

$500

Step-by-step explanation:

if Marco gets $50 for every 2 hours and it say how much he'll have every 10 hours what your gonna do is multiply 10 by 50 so 10×50= 500 so Marco will make $500 every 10 hours

$250 will he make in 10 hours for the work that Marco has done.

When you take a single number and multiply it by several, you are multiplying. There are a number of distinct indications of amplification that people utilize. The "x" sign represents the most typical, however, other symbols like the "*" sign are also occasionally used.

The information that is provided is:

Marco made $50 for the two hours he is working for.

For one hour of the work that he is doing the amount that he will be paid is

= 50 / 2

$25

For working 10 hours Marco will earn

= 10*25

$250
