Answer:

the product does not exits

The product matrix is,

[tex]\left[\begin{array}{ccc}-10&-4\\13&-5\\\end{array}\right][/tex]

In mathematics, a matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.

For example, is a matrix with two rows and three columns.

here, we have,

two matrices,

A = 2×3

and, B= 3×2,

as the no. of column of A = the no. of row of B

the can be a product matrix of order 2×2.

Now, we get,

the product matrix is,

[tex]\left[\begin{array}{ccc}-10&-4\\13&-5\\\end{array}\right][/tex]

Answer:

Step-by-step explanation:

2x - 5 = 15

Bringing like terms on one side

2x = 15 + 5

2x = 20

Option B is the correct answer

Answer:

b) 2x = 20

c) 2(x - 5) = 15

D) 2x - 20 = 0

Explanation

2x - 5 = 15

2x = 15 + 5

2x = 20

x= 20/2

x= 10

a) 2x = 10

x= 10/2

x= 5 (which is not correct)

b) 2x = 20

x= 20/2

x = 10 (which is correct )

c) 2(x- 5) = 15

2x - 10 = 15.

2x = 15 +10

2x = 20

x = 20/2

x= 10 ( which is correct)

d) 2x - 20 = 0

2x = 20

x= 20/2

x= 10 ( which is correct)

y =3

After you set each equation to terms where you can cancel out the x

The primitive function for [tex]f(x) = 4e^{2x} + e^{-x}[/tex] is given by it's indefinite integral.

To calculate it, recall:

[tex]\frac{d}{dx}e^{ax}=ae^{ax}[/tex]

[tex]\int c f(x)dx = c\int f(x)dx[/tex]

Let's begin

[tex]\int 4e^{2x}+e^{-x}dx \\4\int e^{2x}dx+ \int e^{-x}dx\\4\frac{e^{2x}}{2}+\frac{e^{-x}}{-1} + c\\[/tex]

[tex]F(x) = 2e^{2x}-e^{-x} +c[/tex]

To find the costant, we just need to use the fact that [tex]F(0)=2[/tex]

[tex]F(0) = 2 \\4e^{0}+e^{0} + c =2\\5+c =2\\c=-3[/tex]

Therefore,

[tex]\boxed{F(x) = 2e^{2x} - e^{-x} -3 }[/tex]

Answer:

14 im pertty sure

Step-by-step explanation:

Replace f(x) with f(3)

f(3) = -3x - 2

This means that you replace any x values with 3

f(3) = -3(3) - 2

Now solve. Multiply first then subtract

f(3) = -9 - 2

(f3) = -11

Answer:

S= B x 2 -7 should work

Step-by-step explanation:

Sarahs age is equal to Bills age×2 but 7 less so Sarah= Bill x 2 -7

Sarah’s age is 7 less than 2 times Bill’s age is written as s=2b-7

An expression is combination of variables, numbers and operators.

Given,

Let Sarah's age is denoted by s

Bill’s age is denoted by b

Given that Sarah’s age (s) is 7 less than 2 times Bill’s age, (b

We need to write this sentence as expression.

Sarah’s age (s) is 7 less than means Sarahs age should be subtracted of 7.

2 times Bill’s age

2 times means we have to multiply bills age with 2.

s equal to 2 times b minus seven.

s=2b-7.

Hence, Sarah’s age is 7 less than 2 times Bill’s age is written as s=2b-7

Step-by-step explanation:

Note that the x-coordinate of both given points is the same:  -2.  This means that x does not change and also that y changes from -4 to 4.  The slope is undefined because division by zero is not defined:

Answer:

Factoring the term [tex]3x^2-75[/tex] we get [tex]\mathbf{3(x+5)(x-5)}[/tex]

Step-by-step explanation:

We need to solve the polynomial: [tex]3x^2-75[/tex]

First we see that 3 is common term, so taking 3 as common

[tex]3(x^2-25)[/tex]

We know that 25 = 5x5 = 5²

So, replacing 25 with 5²

[tex]3(x^2-5^2)[/tex]

We know that, [tex]a^2-b^2=(a-b)(a+b)[/tex]

Applying this in our equation: [tex]x^2-5^2=(x+5)(x-5)[/tex]

[tex]3(x+5)(x-5)[/tex]

So, factoring the term [tex]3x^2-75[/tex] we get [tex]\mathbf{3(x+5)(x-5)}[/tex]

Answer:

The art teacher needs 73 containers to store all the colored pencils.  

Step-by-step explanation:

1,314 colored pencils ÷ 18 pencils per container = 73 containers total

The number of containers the art teacher need to store all the colored pencils is 73.

Given that, the art teacher buys containers to store 1,314 colored pencils.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here, each container holds 18 pencils.

Number of containers = Total number of pencils/Number of pencils in each container

= 1314/18

= 73

Therefore, the number of containers the art teacher need to store all the colored pencils is 73.
