The vertex of the graph for the given equation is (-1, -8).

The differentiation of a function is defined as rate of change of its value at a point. It can be written as f'(x) = (f(x + h) - f(x)) /(x + h - x).

Its geometrical aspect is the slope of the tangent at a given point.

The given equation is y = 2x² + 4x - 6.

The vertex is a point at the graph where the slope becomes zero. It can be found by equating the differentiation of the equation to zero as below,

y = 2x² + 4x - 6

=> y' = 4x + 4 = 0

=> x = -1

At x = -1 the value of y can be found as,

y = 2 × -1² + 4 × -1 - 6

  = 2 - 4 - 6

  = -8

Thus, the vertex is given as (-1, -8) which is only valid for option (b).

Hence, the key points to be used by sandy to draw the graph are x-intercept (1, 0), y-intercept (-3, 0) and vertex (-1, -8).

The slope of a line parallel to the line 8x - 6y = -24 is 4/3.

The slope-intercept formula is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the equation of the line.

8x - 6y = -24

First, rewrite in slope-intercept form.

8x - 6y = -24

Solve for y

8x + 24 = 6y

6y = 8x + 24

y = (8/6)x + 24/6

y = (4/3) + 4

Now, from the slope-intercept form;

y = mx + b

Where m is the slope

Slope of the line y = (4/3) + 4 will be

m = 4/3

All line parallel to the line y = (4/3) + 4 must have the same slope.

Hence, the slope of a parallel line to the line y = (4/3) + 4 will be;

m_parallel = 4/3

Therefore, the slope of the parallel line is 4/3.

In given expression constant term is 4, degree of expression is 2, coefficient of second term is 5 and at x=-1 value of expression is 6.

The highest or greatest power of a variable in a polynomial equation is referred to as the degree of the polynomial.

The degree denotes the polynomial's highest exponential power.

A term in an equation with a fixed value that is unaffected by variations in the variable.

A constant is typically represented as c to reflect a fixed value when written as a variable.

The usage of the word "variable" in this terminology may be perplexing, but all it really implies is that c is a variable that may stand in for any fixed value.

Given: p(x)=7x²+5x+4

(a) Constant term is coefficient of [tex]x^{0}[/tex].

So constant term in given equation is 4.

(b) Degree of expression is highest power of x in the expression. For our expression we have two as our highest power.

So, degree of expression is 2.

(c) Coefficient of second term is 5.

(d) On substituting value of x as -1, we get

7× (-1)² +5(-1) +4 = 7-5+4 = 6

So, value of expression at x=-1 is 6.

Answer:

The answer is 6, I am going to give you a explanation just in case you need one.

Step-by-step explanation:

We are going to refer seed packets as SP just to make it more simple. And flowers F this is just to make it easier on ourselves.

Ok since we know that in order to plant 9 F we need 3 SP.

If we do the equation correctly we should get

3 SP × ? = 9

In order to do this there is two ways I am going with the easier one we just have to add 3 to 3 until we get 9 ok so 3 + 3 = 6 so lets add more 3's 6 + 3 = 9 great so this means 3 + 3 + 3 = 9. Now if  you noticed he had three three's which means our equation now is

3 SP × 3 = 9

Now that we are done with the first part it should just get easier from here.

We know that each SP has 3 F to grow and each SP has 9 F to grow we just have to do 9 + 9 which gives us 18.

Therefore the answer is 2 SP needed to plant 18 flowers.

Answer:

perimeter is 6 times as long as the width

Step-by-step explanation:

let width be w then length l = 2w

perimeter (P) of a rectangle is calculated as

P = 2(l + w )

  = 2(2w + w)

 = 2(3w)

 = 6w

Perimeter is 6 times as long as the width

The width of the rectangle is (1/6) times long as the perimeter of the rectangle.

The area of a rectangle is given by -

A{R} = Length x Breadth

A{R} = L x B

Given is the length of a rectangle is twice its width.

Assume the width of the rectangle be [x] units. Then, the length will be [2x] units. For the width of the rectangle to be as long as the perimeter of the rectangle -

{P} = 2{L + B} = 2{x + 2x} = 6x

Now -

{w} = x

So, we can write that -

{P} = 6{w}

{w} = {1/6}{P}

Therefore, the width of the rectangle is (1/6) times long as the perimeter of the rectangle.

Two or more expressions with an Equal sign is called as Equation.

Given,

Salad 'n Scoops is a food truck that sells salads for $4 and scoops of ice cream for $2

On a hot July day, they had 118 customers and earned $326.

Let x be the number of scoops of ice cream sold and y be the number of salads sold that day.

In 2011 we can predict there will be only 1.13 million VHS movie rentals.

A regression equation is utilized in details to figure out what relationship, if any, exists between sets of information. For instance, assuming that you measure a kid's level consistently you could find that they develop around 3 inches a year. That pattern (growing three inches a year) can be displayed with a regression equation.

The remarkable relapse condition is the dramatic capability that best fits the arrangement of information and it is given in the structure:

y = a · bˣ

where:

a = beginning worth of the model

b = remarkable develop or rot

x = time elapsed all along

For our situation,

y = 9.92 · (0.8208)ˣ

where:

a = 9.92

b = 0.8208

Since 0 < b < 1 we have an outstanding rot, affirming that the quantity of VHS is diminishing with time.

We can then utilize this condition to gather the quantity of VHS motion pictures in 2011.

As something first, compute how long all along (2000) would pass:

The equation of the line tangent to the graph of g at the point where x = 1 y + 10x + 44 =0.

What is line tangent?

A line that touches a curve at one point is said to be tangent. A point of tangency is the location where a curve and a line intersect. Y = mx + b is the slope-intercept formula for a line, where m is the line's slope. The straight line that "just touches" the curve at a particular location is referred to as the tangent line to a plane curve in geometry. It was described by Leibniz as the path connecting two points on a curve that are infinitely near together.

Given g(x)=f(2x)

Differentiate it on both side with respect to x.

[tex]\begin{aligned}& \frac{d g(x)}{d x}=2 * \frac{d f(2 x)}{d x} \\& \frac{d g(-1)}{d x}=2 * \frac{d f(-8)}{d x}=-5^* 2=-10\end{aligned}[/tex]

Answer:

  y = 8x -11

Step-by-step explanation:

You want the equation of the line tangent to g(x) = f(2x-6) at x=1, where f is a differentiable function with f(1) = 2, f(-4) = -3, f'(1) = 3, f'(-4) = 4.

The equation of the tangent line at x=1 can be written ...

  y = g'(1)(x -1) +g(1)

The necessary function values are ...

  g(1) = f(2·1 -6) = f(-4) = -3

and

  g'(x) = f'(2x -6)·(2x -6)' = 2f'(2x -6)

  g'(1) = 2f'(2·1 -6) = 2f'(-4) = 8

Then the equation of the line is ...

  y = 8(x -1) +(-3) = 8x -8 -3

  y = 8x -11 . . . . . . tangent to g(x) at x=1

Step-by-step explanation:

The triangle shown in the image is an isosceles triangle.

We can find the value of x using the above mentioned information:

∠B = ∠A

5x = 40 divide both sides by 5

x = 8

The sum of interior angles in a triangle is equal to 180°.

Since ∠B and ∠C are both 40°:

40 + 40 + 3y - 8 = 180 add/subtract like terms

72 + 3y = 180 subtract 73 from both sides

3y = 108 divide both sides by 3

y = 36
