Answer:

(1, 4)

Step-by-step explanation:

5x-2y=-3 -2x-y=-6  =>

5x-2y=-3

-2x-y=-6   Multiply all three terms by -2:  4x + 2y = 12

Then we have:

5x-2y=-3

4x + 2y = 12

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

 9x = 9 and so x = 1.  Then, using -2x - y = -6,  and substituting 1 for x:

-2(1) - y = -6, or

2 + y = 6, or

y = 4

Then the solution is (1, 4)

Answer:

m = 7

Step-by-step explanation:

An angle bisector is a line or ray that divides an angle into two equal angles

so ∠WXZ = ∠ZXY

10m - 28 = 5m + 7

10m - 5m = 7 + 28

5m = 35

m = 7

Step-by-step explanation:

The difference between 3n³ + 4n² - 9 and -2n³ + 4n - 9 is 5n³ + 4n² - 4n

Given,

The two expressions are:

a = 3n³ + 4n² - 9

b = -2n³ + 4n - 9

We have to find a - b:

That is,

(3n³ + 4n² - 9) - ( -2n³ + 4n - 9)

Open the bracket and multiply (-) with the terms.

That is,

3n³ + 4n² - 9 + 2n³ - 4n + 9

Now solve the expression:

We get,

3n³ + 4n² + 2n³ - 4n

Add 3n³ and 2n²

Then,

5n³ + 4n² -4n

Therefore, the difference between 3n³ + 4n² - 9 and -2n³ + 4n - 9 is 5n³ + 4n² - 4n

Explanation:

The term "bisect" means "divide in half", or "divide in two equal pieces".

Angles A = 58 and B = 96 divide in half to get 29 and 48 respectively

Find their sum and subtract it from 180 to get angle AMB

29+48 = 77

Answer: B. 1/8

Step-by-step explanation:

The value of  the variable in the isosceles trapezoid is 24.

Since the measure of one angle should be 63 degrees

And, there is the equation 2x + 15 degrees

So for determining the value of x here we have to equate the equation

So,

2x + 15 = 63

2x = 63 - 15

2x = 48

x = 24

Therefore, The value of  the variable in the isosceles trapezoid is 24.

Step-by-step explanation:

Katie requires 16/3 cups of the soil for planting a garden for her science fair.

Algebra is a mathematical technique for calculating unknown values.

Now, for the stated question;

Katie has been planting a garden for her science fair project. She requires 2/3 of a cup of soil for each of the eight pots.

To calculate the total amount of soil required, multiply the amount required for one pot by the number of total pots.

Total soil  = (2/3)×8

Total soil  = (2×8)/3

Total soil  = 16/3

Therefore, the total amount of the soil requires for the gardening in science fair is 16/3 cups.

Step-by-step explanation:

Here I listed all the factors of each number:

35: 1, 5, 7, 35

56: 1, 2, 4, 7, 8, 14, 28, 56

As you can see, the LCM of these numbers is 1, since none of the other factors relate to all of the number's factors. This is also the only factor that all three of these numbers share.

1 + 1 + 1 = 3

The GCF of each of the numbers is also 1.

1 + 1 + 1 = 3

Answer: he works 37 hours in job A, and 22 hours in job B.

Step-by-step explanation:

Let's define the variables:

A = number of hours that he works at Job A

B  = number of hours that he works at Job B.

We know that he works a total of 59hr per week, then we have:

A + B = 59

And we also know that he makes $494 in one week, then we have the equation:

A*$8 + B*$9 = $494.

Then we have the system of equations:

A + B = 59

A*$8 + B*$9 = $494

To solve this with an augmented matrix, we need to turn these equations into a matrix, where we only write the coefficients as follows:

[tex]\left[\begin{array}{cccc}1&1&I&59\\8&9&I&494\end{array}\right][/tex]

(The I's should represent a line for the augmented matrix, that line separates the values of the coefficients to the right value of each equation)

The first column represents the A coefficients, the second column represents the B coefficients.

To solve this, we want to get something of the form:

[tex]\left[\begin{array}{cccc}1&0&I&x\\0&1&I&y\end{array}\right][/tex]

Where x and y are our solutions.

To do it we can just do: Column 2 - 8*column 1, this will get us to:

[tex]\left[\begin{array}{cccc}1&1&I&59\\8 - 8*1&9 - 8*1&I&494 - 8*59\end{array}\right][/tex]

=

[tex]\left[\begin{array}{cccc}1&1&I&59\\0&1&I&22\end{array}\right][/tex]

Now we can do: Column1 - column2, to get

[tex]\left[\begin{array}{cccc}1 - 0&1 - 1&I&59 - 22\\0&1&I&22\end{array}\right][/tex]

[tex]\left[\begin{array}{cccc}1&0&I&37\\0&1&I&22\end{array}\right][/tex]

Then the solutions are:

1*A =37

1*B = 22

This means that he works 37 hours in job A, and 22 hours in job B.
