Solve for x and graph.|x+5| = .01

The equation of the line is given as y = -2x + 22. This means that when x  is equal to zero, y = 22. M also shows how steep the line is, being the gradient.

In order to arrive at a logical solution, we must assume the value of the slope as this is not given.

Assuming the slope of the line is -2, we thus can say:

The equation of a line that passes through a point (x₁,y₁) and a slope m is given by

(y - y1) = m (x - x1)

Recall that the slope, m = -2

While
Point (x1, y1) = (7, 8)

Hence, the equation of the line is:

y-8 = (-2) (x-7)

y-8 = -2x + 14

y = -2x+ 14 + 8

Hence,

y = -2x + 22

Thus, the equation of the line is:
y = -2x + 22

The revenue is at a maximum after x = 9

The maximum is $ 261

9 hearing aids are produced and sold.

The revenue, R(x), of producing and selling 'x' Awesome Hearing Aids is modeled by the function,

R(x) = -3x² + 56x

We need to find the number of hearing aids produced and sold in order to maximize the revenue.

We use the differentiation method to find the maximum of the function R(x).

Differentiate R(x) with respect to x and equate it with 0,

R'(x) = -6x + 56

Then, -6x + 56 = 0

⇒ 6x = 56

⇒ x = 56/6 = 9.33 ≈ 9  [since x is the number of hearing aids]

Now we find the second derivative of R(x) at x = 9.

R''(x) = -6

⇒ R''(9) = -6 < 0

Since R''(9) < 0, the revenue R(x) is maximum at x = 9.

So the maximum revenue is obtained after x = 9.

Therefore maximum revenue = R(9) = -3 x 9²+56 x 9 = $ 261

Hearing aids produced and sold in order to maximize the revenue = 9

The triangle’s enlargement dimensions will be 52.8 cm by 80 cm.

The size by which the shape is enlarged or reduced is called as its scale factor.

Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape.

It is used to increase or decrease the size of an object.

The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.

For example, a rectangle has a length of 5 units and a width of 2 units. Now, if we increase the size of this rectangle by a scale factor of 2, the sides will become 10 units and 4 units, respectively. Hence, we can use the scale factor to get the dimensions of the changed figures.

Given:

A triangle’s original dimensions are 24 cm by 40 cm

scale factor=2.2

Thus,

enlarged dimensions= scale factor x original dimensions

[2.2] x 24 = 52.8 cm

[2.2] x 40 = 80 cm

Hence, the triangle’s enlargement dimensions will be 52.8 cm by 80 cm.

The x-intercepts in the graph are ( - 2, 0 ), ( 1, 0 ) and ( - 1, 0 ) and the y-intercepts of the graph is ( 0, 6). The graph of the function tends to infinity in the negative y-axis direction after intersecting the x-axis at ( 1, 0).

Consider the function,

f(x) = - 3x³ - 6x² + 3x + 6

To find the x-intercept of the function we substitute y = 0.

f(x) = y = - 3x³ - 6x² + 3x + 6

- 3x³ - 6x² + 3x + 6 = 0

3x³ + 6x² - 3x - 6 = 0

3x²( x + 2 ) - 3 ( x - 2) = 0

( x + 2 )( 3x² - 3) = 0

Therefore,

x = - 2 and;

3x² - 3 = 0

3x² = 3

x = ± 1

Hence, the x-intercepts are ( - 2, 0 ), ( 1, 0 ) and ( - 1, 0 ).

Now, the y-intercept will be when x = 0,

y = - 3x³ - 6x² + 3x + 6

y = - 3(0)³ - 6(0)² + 3(0) + 6

y = 6

Hence, the y-intercept is ( 0, 6).

The graph of the function intersects the x-axis at ( - 2, 0) and ( - 1, 0 ) and then intersects the y-axis at ( 0, 6) then after intersecting the x-axis at ( 1, 0 ) the graph tends to infinity in the negative x-axis direction.

The Slope of the line is 3/2 and the y-intercept is at (0,3)

Each solution in the two-variable scenario can be thought of as the Cartesian coordinates of a specific point on the Euclidean plane.

The graph of the line passes through (0,9) and (2,6) .

Slope of the line = (6-9)÷(2-0) = 3/2

Hence the line will have the equation:

y - 6 = 3/2 ( x - 2 )

or, 2y - 12 = 3x - 6

or, 2y - 3x = 6

Hello there. To solve this question, we'll have to remember some properties about dividing polynomials.

Given the polynomials, we want to evaluate the division:

Rewriting it the way we perform long division:

We start with the higher degree terms, namely x^4 and x².

Dividing x^4 by x², we get x². Now we multiply every term from the division by this factor and subtract from the term being divided.

Now, we have a 2x³ as the higher degree term from the term being divided. Dividing it by x², we get 2x. Multiply each term of the divisor and subtract from it.

Finally, the highest degree term from the term being divided is x². Dividing it by x², we get 1. Multiply each term of the divisor and subtract it from the dividend.

Now, the highest degree term from the dividend is -x, when the highest degree term from the divisor is x². We cannot proceed with the long division anymore.

It means that we have a quotient:

And a remainder:

Notice if we rewrite it as:

We have the division P(x)/D(x) written in the form:

Where Q(x) and R(x) are the quotient and remainder polynomials.

Based on the fact that 150g of syrup are needed when making 8 flapjacks, the quantity that is needed to make 16 flapjacks is 300 g.

The quantity of oats needed to make 8 flapjacks is 150 g.

Assuming direct proportion, the quantity of oats needed to make 16 flapjacks can be found by the formula:

= (Quantity of oats needed for 8 flapjacks x Number of flapjacks to be made) / Number of flapjacks made

Solving for the quantity of oats needed gives:
= (150 x 16) / 8
