Find the equation of the line passing through points (6,0) and (-1,14).
Oy = 6x
y = -2x + 12
y = -2x + 14
y = 2x + 10

Answer:

1 in 10

Step-by-step explanation:

The equation in slope-intercept form that represents the function is: g(x) = -2x + 1.

To write the slope-intercept form of an equation that represents the linear function g, find the slope (m) of the line and determine the y-intercept (b) of the line, then substitute the values into g(x) = mx + b.

Slope of the line that represents function g = change in y/change in x = -6 units/3 units

Slope of the line (m) = -6/3

Slope of the line (m) = -2.

The line intercepts the y-axis at y = 1, therefore the y-intercept (b) of the linear function is b = 1.

To write the equation representing the function, substitute m = -2 and b = 1 into g(x) = mx + b:

g(x) = -2x + 1

The marginal profit is -41 dollars.

In accounting, a profit is an income that is given to the owner throughout a successful market producing process (business).

The advertising is given by P(x) = 930 + 15x -4x².

The marginal profit at x = 7 is given by

P(x) = 930 + 15x -4x²

P'(x) = 15 - 8x

Now at x = 7 the marginal profit is

P'(7) = 15 - ( 8×7 )

or, P'(7) = -41

Hence there will be marginal profit of -41 dollars.

Answer:

  [tex]y=\begin{cases}-\dfrac{7}{2}x-16&\text{for $-6\le x\le-4$}\\\\\dfrac{1}{5}x-\dfrac{6}{5}&\text{for $-4 < x < 1$}\\\\\dfrac{9}{4}x-\dfrac{13}{4}&\text{for $1\le x\le 5$}}\end{cases}[/tex]

Step-by-step explanation:

You want the piecewise function that describes the relation shown in the graph.

The relation shown consists of three line segments connecting the points ...

  (-6, 5) and (-4, -2)

  (-4, -2) and (1, -1)

  (1, -1) and (5, 8)

The equations for the lines between the pairs of points can be written using the slope formula and the point-slope equation of a line.

The slope formula tells you the slope is ...

  m = (y2 -y1)/(x2 -x1)

And the point-slope equation of a line is ...

  y -y1 = m(x -x1)

If we add y1 to the equation of the line, and substitute the equation for m, we get ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . . . a 2-point formula for a line

Between x-values -6 and -4, the equation of the line will use the first pair of points:

  y = (-2 -5)/(-4 -(-6))(x -(-6)) +5

  y = -7/2(x +6) +5 = -7/2x -16

Between x-values -4 and 1, the equation of the line will use the second pair of points:

  y = (-1-(-2))/(1 -(-4))(x -(-4)) +(-2)

  y = 1/5(x +4) -2 = 1/5x -6/5

Between x-values 1 and 5, the equation of the line will use the last pair of points:

  y = (8 -(-1))/(5 -1)(x -1) +(-1)

  y = 9/4(x -1) -1 = 9/4x -13/4

The piecewise function uses the equation for the line that is applicable for the appropriate x-values. We have listed those sets of x-values above.

We need to make sure that the function has only one definition for any given value of x. When two segments have a point in common, we need to make sure only one segment includes it.

  [tex]y=\begin{cases}-\dfrac{7}{2}x-16&\text{for $-6\le x\le-4$}\\\\\dfrac{1}{5}x-\dfrac{6}{5}&\text{for $-4 < x < 1$}\\\\\dfrac{9}{4}x-\dfrac{13}{4}&\text{for $1\le x\le 5$}}\end{cases}[/tex]

Step-by-step explanation:

The equation for two different bowling alleys is 2x - 3y = -2

This is a problem from algebraic equations. We can solve this problem by following a few steps.

In the first case, he paid $7 to rent a pair of shoes and x dollars an hour to bowl and bowled for 2 hours on Friday.

Here, the cost to bowl for one hour is x dollars. So, the cost to bowl for 2 hours is ( 2× x ) = 2x

Now, the total expenditure for shoes and to bowl is, (2x + 7) dollars

In the second case, he paid $5 to rent a pair of shoes and y dollars an hour to bowl and bowled for 3 hours on Saturday.

Here, the cost to bowl for one hour is y dollars. So, the cost to bowl for 3 hours is (3 × y) = 3y

Now, the total expenditure for shoes and to bowl is, (3y + 5) dollars.

As the total expenditure is the same in these two cases. Therefore, we can conclude,

(2x + 7) = (3y + 5)

Or, 2x - 3y = -2

The equation of the perpendicular line is y = x + 3

Perpendicular line:

The perpendicular line means a straight line that makes the right angle (90 degrees) with the other line.

Given,

Here we have the equation y = -x + 3.

Now, we need to find the equation of the perpendicular line.

In order to find the equation of a perpendicular line, first we need to find the negative reciprocal of the slope given.

Through the given equation we have identified the slope of the line is -1. so the slope of the perpendicular line will be 1.

While looking at the graph we have identified the y intercept of the equation is 3.

So now we know the values of y-intercept and slope.

We just put them together, and apply it one the standard form of the equation of line, then we get,

y = 1x + 3

y = x + 3.

Therefore, the equation of perpendicular line is y = x +3.

The solution for the quadratic equation is -5/2, 2/3

Given,

The equation: 18a² - 30 = -33a

We have to solve this equation

We can convert this equation into a quadratic equation:

18a² + 33a - 30 = 0

Now lets solve this quadratic equation with quadratic formula:

Quadratic formula = [tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]

Here,

a = 18, b = 33 and c = -30

Now we can solve:

[tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]

= [tex]\frac{-33(+-)\sqrt{33^{2} -4(18)(-30)} }{2(18)}[/tex]

=  [tex]\frac{-33(+-)\sqrt{1089-(-2160)} }{36}[/tex]

= [tex]\frac{-33(+-)\sqrt{1089+2160} }{36}[/tex]

= (- 33 ± √3249) / 36

= (- 33 ± 57) / 36

Solve for:

(- 33 + 57) / 36 = 24/36 = 2/3

Solve for:

(- 33 - 57) / 36 = - 90/36 = - 30/12 = -10/4 = -5/2

The unknown angle for the given right triangle ABC which is angle A is: 63°

We are given the angles of a right angle triangle ABC as;

∠B = 90°

∠C = 27°

Now, it is pertinent to note that the sum of all angles in any given triangle is always 180°. This means that in our right angle triangle ABC, we can say that;

∠A + ∠B + ∠C =  180°

Thus;

∠A + 90 + 27 = 180

∠A + 117 = 180

∠A = 180 - 117

∠A = 63°

Thus, we conclude that the value of angle A is gotten as ∠A = 63°

The required implicit solution to the initial-value problem would be  5x²- y² = 9.5 which is the equation of a hyperbola.

Hyperbola is defined as a conic section, a two-branched open curve, produced by the intersection of a circular cone.

(x-h)²/b² - (y-k)²/a² = 1

We have been given that 5x²- y² = c is a one-parameter family of solutions of the differential equation.

To determine an implicit solution to the initial-value problem ydy/dx = 5x

⇒ y dy/dx = 5x

⇒ y dy = 5x dx

⇒ y²/2 = 5x²/2 + c

If y(3) = −8 which is the means that when substitute x = 3 then y = -8

⇒ (-8)²/2 = 5(3)²/2 + c

⇒ 64/2 = 5(9)/2 + c

⇒ 32 = 22.5 + c

⇒ c = 9.5

Substitute the value of c in the given function 5x²- y² = c

⇒ 5x²- y² = 9.5 which is the equation of a hyperbola.

Therefore, the implicit solution to the initial-value problem would be  5x²- y² = 9.5.

The  quadratic equation that opens down and has vertex at (2,-8) is y = (-|a|)*(x - 2)² + (-8).

The graph of a quadratic function has the shape of a parabola. Although a parabola's "width" or "steepness" and direction of opening can differ, they all have the same basic "U" shape.  If the leading coefficient is larger than zero, the parabola opens upward; if it is less than zero, it opens downward.

The quadratic equation's vertex form is y = a*(x - h)2 + k.

Given that (2,-8) or (h, k) is the vertex point (2,-8)

Since the graph starts out downward, a will have a negative value.

Since |a| is the magnitude of a, the quadratic equation will then be written as y = (-|a|)*(x - 2)2 + (-8).

Consequently, y = (-|a|)*(x - 2)2 + is a quadratic equation that opens downward and has a vertex at (2,-8). (-8).

A percentage refers to the ratio of a variable expressed as a fraction of 100.

Percentages show the proportional value contained in another.

We use the percent sign (%) to denote percentages, which may be increases or decreases.

Initial value = £50

Percentage decrease = 60%

Percentage change = 40% (1 - 60%)

In monetary terms, the final value after the percentage decrease = £20 (£50 x (1 - 60%).
