The equation of the line passing through points (5, 18) and (8, 9) will be y = - 3x + 33.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The points are given below.

(5, 18) and (8, 9)

The points (5, 18) and (8, 9) will satisfy the equation y = mx + c, then the equations are given as,

18 = 5m + c          ...1

9 = 8m + c           ...2

From equations 1 and 2, then we have

18 - 9 = 5m - 8m

3m = - 9

m = -3

Then the value of 'c' is given as,

9 = 8(-3) + c

9 = - 24 + c

c = 33

The equation is written as y = -3x + 33.

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.

An equation to represent the other lengths, X, of the triangle is 2X+7=23.

An isosceles triangle is one that has two equal-length sides in geometry. The term "equilateral triangle" can refer to a shape with either exactly two sides that are the same length or at least two sides that are the same length, with the latter definition containing the equilateral triangle as an exception. The faces of bipyramids and a few Catalan solids are examples of isosceles triangles, as are the isosceles right triangle, the golden triangle, and others.

Isosceles triangles have been the subject of mathematical research since the time of the Babylonians and the Egyptians.

Given,

Perimeter of an isosceles triangle=23 meters

The base of a triangle=7 meters

P=2X+b

2X+7=23

Therefore, an equation to represent the other lengths, X, of the triangle is 2X+7=23.

7y = -3x + 7

y = -3/7x + 1

Answer:

x = 8

y = 36

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

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 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:

x = 2011 - 2000 = 11

Presently, substitute this worth in the situation:

y = 9.92 · (0.8208)¹¹

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]

Slope =-10

g(-4)=f(-8)=-4 = y coordinate

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

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).

Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

Here, we have

A plane leaves Charlotte at 9:00 AM and flies north at 400 knots. At the same time, another plane flies south from Charlotte at 250 knots

The speeds are added when going in opposite directions = 400 + 250knots =  650 knots
