What is the answer for x? 7/9 - x/9 = 1/3 Please answer ASAP!!!!!

Answer:

28

Step-by-step explanation:

Substitute x = - 2 into the expression, that is

(- 2)² - 7(- 2) + 10 = 4 + 14 + 10 = 28

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)

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:

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.

Answer:

f(-4) = 33

f(7) = -154

Step-by-step explanation:

In this question, you will solve the function by plugging in the given value.

Solve:

f(-4) = 7 - 2(-4) -3(-4)²​

= 7 - 2(-4) - 48

= 7 + 8 - 48

= 7 - 40

f(-4) = 33

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

f(7) = 7 - 2(7) -3(7)²​

= 7 - 2(7) - 147

= 7 - 14 - 147

= 7 - 161

f(7) = -154

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:

m = (change in y) / (change in x) = 8/0:  undefined

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:

m = (change in y) / (change in x) = 8/0:  undefined

Answer:
