Answer:

y = -3x + 2

Step-by-step explanation:

Ok so I assumed that you are setting this equal to 0 or there would be an equal sign in the equation.  So basically you just want to gather like terms on each side so the y's on the left and the x's on the right.  You then want to solve using algebra and you have your answer!  I will add a picture to show my steps.

Answer:

Area of carpet = 177.625 ft²

Step-by-step explanation:

Given:

Length of room = [tex]14\frac{1}{2}[/tex] = 14.5 ft

Width of room = [tex]12\frac{1}{4}[/tex] = 12.25 ft

Find:

Area of carpet

Computation:

Area of carpet = lb

Area of carpet = (14.5)(12.25)

Area of carpet = 177.625 ft²

Micheal estimation = 15.5 x 12.25 = 189.875

Tracy estimation = 12.25 x 15.5 = 189.875

Both wrong.

Answer:

1/3

Step-by-step explanation:

y=mx+b

m= Slope

So, 1/3 is the slope.

Answer:

y = 4x +1

Step-by-step explanation:

6x + 1 = y + 2x

First you need to solve for y, so then you need to

1. Combine like terms

So since there isn't anything to combine we can more on.

2. Make Y by itself

You need to subtract the 2x from both side to get the answer

y = 4x +1

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, it is given that :

number of rows = m³

number of columns = m^(5)

Now, we have to find the number of tiles in a wall

= rows *  column

=  m³ *  m^(5)

= m^(3+5)

= m^(8)

hence, the number of tiles in a wall is m^(8)

Answer:

The length is 15 inches.

Step-by-step explanation:

Perimeter of rectangle = 2L + 2W

If W = 6, then 2W = 2*6, which is 12.

Now, 2L + 12 = 42.

Solve for L.

2L + 12 = 42

2L = 30

L = 15

Answer: C. [tex]B=\left[\begin{array}{ccc}1\\3\\-5\end{array}\right][/tex]

Step-by-step explanation: I got this right on Edmentum.

Several operations such as addition, subtraction, multiplication, etc. can be performed on matrices. The value of matrix B is:

[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]

Given that:

[tex]A =\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right][/tex]

[tex]AB =\left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]

Let matrix B be:

[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]

The product of A and B is as follows:

[tex]\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right] \times\left[\begin{array}{c}a&b&c\end{array}\right][/tex]

Multiply the rows of A to the column of B. So, we have:

[tex]AB =\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right][/tex]

This means that:

[tex]\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right] = \left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]

By comparison, we have:

[tex]2a + 4b - 2c = 24[/tex] --- (1)

[tex]4a - 5b + 7c = -46[/tex] --- (2)

[tex]2a + 7b + 5c = -2[/tex] --- (3)

Multiply (1) and (3) by 2

[tex]2a + 4b - 2c = 24[/tex] --- (1)

[tex]4a + 8b - 4c = 48[/tex] ----- (5)

[tex]2a + 7b + 5c = -2[/tex] --- (3)

[tex]4a + 14b + 10c = -4[/tex] ---- (6)

So, we have:

[tex]4a - 5b + 7c = -46[/tex] --- (2)

[tex]4a + 8b - 4c = 48[/tex] ----- (5)

[tex]4a + 14b + 10c = -4[/tex] ---- (6)

Make 4a the subject in each of the equations

[tex]4a = -46 + 5b - 7c[/tex]

[tex]4a = 48 - 8b + 4c[/tex]

[tex]4a = -4 - 14b - 10c[/tex]

[tex]4a = 4a[/tex]. So, we have:

[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex]  and  [tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]

Simplify both expressions

[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex]

[tex]5b + 8b - 7c - 4c = 48 + 46[/tex]

[tex]13b - 11c = 94[/tex]

[tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]

[tex]5b+14b - 7c + 10c = 46-4[/tex]

[tex]19b + 3c = 42[/tex]

Make c the subject

[tex]c = \frac{42 -19b}{3}[/tex]

Substitute [tex]c = \frac{42 -19b}{3}[/tex] in [tex]13b - 11c = 94[/tex]

[tex]13b - 11 \times (\frac{42 - 19b}{3}) = 94[/tex]

Multiply through by 3

[tex]39b - 11 \times (42 - 19b) = 282[/tex]

Open bracket

[tex]39b - 462 + 209b = 282[/tex]

Collect like terms

[tex]39b + 209b = 282+462[/tex]

[tex]248b = 744[/tex]

Solve for b

[tex]b = \frac{744}{248}[/tex]

[tex]b = 3[/tex]

Solve for c

[tex]c = \frac{42 -19b}{3}[/tex]

[tex]c = \frac{42 - 19 \times 3}{3}[/tex]

[tex]c = \frac{-15}{3}[/tex]

[tex]c = -5[/tex]

Solve for a in [tex]4a = -4 - 14b - 10c[/tex]

[tex]4a = -4 - 14 \times 3 - 10 \times -5[/tex]

[tex]4a = 4[/tex]

Divide by 4

[tex]a = 1[/tex]

Recall that matrix B is:

[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]

Hence, the value of matrix B is:

[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]
