Answer:

B (5, 13)

Step-by-step explanation:

9x + 4y = 97

9x + 6y = 123

To solve by elimination, we want to eliminate a variable. To do this, we must make one variable cancel out.

First, we can see that both equations have 9x. To cancel out x, we must make one of the 9x's negative. To do this, multiply each term in the equation by -1.

-1(9x + 6y = 123)

-9x - 6y = -123

This is one of your equations. Set it up with your other given equation.

9x + 4y = 97

-9x - 6y = -123

Imagine this is one equation. Since every term is negative, you will be subtracting each term.

9x + 4y = 97

-9x - 6y = -123

___________

0x -2y = -26

-2y = -26

To isolate y further, divide both sides by -2.

y = 13

Now, to find x, plug y back into one of the original equations.

9x + 4(13) = 97

Multiply.

9x + 52 = 97

Subtract.

9x = 45

Divide.

x = 5

Check your answer by plugging both variables into the equation you have not used yet.

-9(5) - 6(13) = -123

-45 - 78 = -123

-123 = -123

Your answer is correct!

Step-by-step explanation:

Metric units are the standard units of measurement while customary units are derived from the metric units. To convert between both units, you need a mix between multiplication and division.

Take distance as an instance.

The metric unit of distance is meters.

The customary units are: feet, inches, yards, miles, etc.

To convert from meters to feet, we multiply by 3.281

For instance:

[tex]2\ meters = 2 \times 3.281\ feet[/tex]

[tex]2\ meters = 6.562\ feet[/tex]

To convert from feet to meter, we divide by 3.281.

For instance:

[tex]6.562\ feet = \frac{6.562}{3.281}\ meters[/tex]

[tex]6.562\ feet = 2\ meters[/tex]

Hence, option (d) is true

Step-by-step explanation:

it is your first choice

-4.4+3.6[tex]\geq[/tex]1.6x

-0.5[tex]\geq[/tex]x

It tells you they are similar. This means the angles are the same, and the sides are proportionate.

Look at the 12 and 4 at the very bottom. This tells you the ratio of the sides. Since 12 / 4 = 3, you can find y with 2 * 3 which is 6.

From that, you also know that 3z = 3y - 2. Substitute the value of y in and you can find z.

Corresponding angles are exactly the same. which means, (3x)° = 100°

You should get x = 33 1/3, y = 6, z = 5 1/3

Answer:

I think the answer is 2 4

Step-by-step explanation:

Table {1} and table {2} represent the relations that are functions.

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

We can define the modulus function as -

|x| = - x     {x < 0}

|x| = x       {x > 0}

Given is to identify which of the relations are functions.

For a relation to be a function, it should have unique value of {y} for a unique value of {x}. One value of {x} cannot have more than one values at the same time. We can see in the image attached that only table 1 and 2 represent such relations. So, we can conclude that relation {1} and {2} represent the functions.

Therefore, table {1} and table {2} represent the relations that are functions.

Answer:

D) 3768 inches

Step-by-step explanation:

Given,

No. of plates = 100

Diameter of each plate = 12inches

So, radius of each plate = 12 / 2 = 6 inches

So, circumference of each plate

[tex] = 2\pi \: r[/tex]

= 2 × 3.14 × 6 inches

= 37.68 inches

Hence, circumference of 100 plates = 100 × 37.68 inches

Answer:

-20z² + 13z - 2.

Step-by-step explanation:

hello !

you use the F.O.I.L method to multiply these two. first, you multiply the first terms, which are:

(-4z)(5z) = -20z²

then, the outside terms, which are:

(-4z)(-2) = 8z

then, the inside terms, which are:

(1)(5z) = 5z

then, lastly, the last terms, which are:

(1)(-2) = -2

Therefore, we get:

-20z² + 8z + 5z - 2.

combine like terms, and the answer is:

-20z² + 13z - 2.

Option 2

Step-by-step explanation:

Go through until you find a true statement:

- The number of observations is 10

Count the number of data points. You should end up with 15, so this option is not correct.

-The median of the data set is 10

To find the median, you know that there are a total of 15 data points, so the median would be the mean of the 7th and 8th (because those are the middle numbers). If you look at the data points, the 7th and 8th points are at 10. The mean of 10 and 10 is just 10,  so that means the median of the set is 10.

This is the correct answer.

If you want, you can also go through the other options and see that none of them work.
