Answer:

b >-54/x^2

Step-by-step explanation:

2-bx^2<56

Subtract 2 from each side

2-2-bx^2<56-2

-bx^2 <54

Divide by -1, remembering to flip the inequality

bx^2 > -54

Divide each side by x^2

bx^2/x^2 > -54/x^2

b >-54/x^2

Answer:

see explanation

Step-by-step explanation:

One way to divide is to use the divisor as a factor in the numerator

Consider the numerator

x²(x - 3) + 3x² - x + 6

= x²(x - 3) + 3x(x - 3) + 9x - x + 6

= x²(x - 3) + 3x(x - 3) + 8(x - 3) + 24 + 6

= x²(x - 3) + 3x(x - 3) + 8(x - 3) + 30

quotient = x² + 3x + 8 , remainder = 30

\frac{x^3-x+6}{x-3} = x² + 3x + 8 + \frac{30}{x-3}

Question 3, help please!
White raven [17]

The answer is not defined.

Explanation:

The given matrix is $\left[\begin{array}{cc}{2} & {4} \\ {1} & {-6}\end{array}\right]+\left[\begin{array}{c}{1} \\ {0}\end{array}\right]$

The matrix $\left[\begin{array}{cc}{2} & {4} \\ {1} & {-6}\end{array}\right]$ has dimensions 2\times 2

This means that the matrix has 2 rows and 2 columns.

Also, the matrix $\left[\begin{array}{l}{1} \\ {0}\end{array}\right]$ has dimensions 2\times1

This means that the matrix has 2 rows and 1 column.

Since, the matrices can be added only if they have the same dimensions.

In other words, to add the matrices, the two matrices must have the same number of rows and same number of columns.

Since, the dimensions of the two matrices are not equal, the addition of these two matrices is not possible.

Hence, the addition of these two matrices is not defined.

Jenny is starting a cake baking business. She plans on selling each cake for $15 and her cost will be $5 per cake. The equipment
Gennadij [26K]
The domain is {0≤x≤200}.

This is because the domain is x, the number of cakes.  The smallest number of cakes she can bake is 0.

Since she is buying enough materials to make 200 cakes, this number is the largest number of cakes she can bake.
