The line y = mx + 6 passes through the point ( 1, 3). find m.

a. The equation that has one solution will be;

⇒ x + 3 = 4x

b. The equation that has no solution will be;

⇒ x + 3 = x

c. The equation that has infinitely many solution will be;

⇒ x + 3 = 3 (x/3 + 1)

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ x + 3

Now,

Use the expression x + 3, we can find as;

Let us defined an expression as;

⇒ x + 3 = 4x

Solve for x as;

⇒ x + 3 = 4x

⇒ x + 3 - 4x = 0

⇒ - 3x = - 3

⇒ x = 1

Hence, The equation has one solution.

Let us defined an expression as;

⇒ x + 3 = x

Solve as;

⇒ x + 3 = x

Subtract x both side, we get;

⇒ x + 3 - x = x - x

⇒  3 ≠ 0

Thus, The equation has no solution.

Let us defined an expression as;

⇒ x + 3 = 3 (x/3 + 1)

Solve as;

⇒ x + 3 = 3 (x/3 + 1)

⇒ x + 3 = 3x/3 + 3

⇒ x + 3 = x + 3

Subtract x we get;

⇒  3 = 3

Thus, The equation has infinitely many solution.

Therefore,

a. The equation that has one solution will be;

⇒ x + 3 = 4x

b. The equation that has no solution will be;

⇒ x + 3 = x

c. The equation that has infinitely many solution will be;

⇒ x + 3 = 3 (x/3 + 1)

The length of BC rounded to 3 decimal places is 4.307 meters.

It states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of squares of the base and perpendicular. Mathematically -

h² = p² + b²

We have the following length and angle as shown in the figure -

[x] = AB = 8.1

θ = ∠BAC = 28°

Using the tangent rule we can write -

tanθ = BC/AB

BC = AB tanθ

BC = 8.1 x tan(28°)

BC = 4.307

Therefore, the length of BC rounded to 3 decimal places is 4.307 meters.

The probability of getting a number < 9 is 28/37.

What is probability?

The ratio of good outcomes to all possible outcomes of an event is known as the probability. It has a range from 0 to 1.

Probability(Event) = Favorable Outcomes / Total Outcomes

Main Body:

Total numbers on the spinner greater than 9  = 37 - 10 + 1 = 28

(we are subtracting 10 because we need number that is greater than 10.)

and adding 1 because both the ends of interval is counted.

total numbers on spinner =37

P( x>9) = 28/37.

Hence the probability of getting a number greater than 9 on spinning is 28/37.

The function (equation) that returns Amir's altitude, y, with respect to time, x,  y = -11·x + 440, when differentiated, to find the rate of change of the altitude, indicates that rate at which Amir descended is D. 11 meters per minute

Differentiation is the process or method by which the derivative of a function is found. The derivative indicates the instantaneous rate at which the value of the function changes with respect to the change in the argument of the function.

The equation of the function that gives his altitude relative to the sea level as a function of time is; y = -11·x + 440

The differentiation of the function for the height, y, in terms of the time, x, gives the speed which is the same as the at which Amir descended as follows;

[tex]Speed = \dfrac{dy}{dx} = \dfrac{d}{dx} \left(-11\cdot x+400\right) = -11[/tex]

Explanation:

In the graph, we can see that there is a point a -4 and nothing lower, making it our minimum y-value. However, we cannot see an ending for the function; therefore, it is indeterminable and thus, infinity.

The pair of lines perpendicular to RS are EA and FG.

A flat surface on which a straight line joining any two points on it would wholly lie is known as a plane.

What is plane?

A plane is a point, a line, and three-dimensional space's equivalent in two dimensions.

Main Body:

Given

E,F and G are on plane X. R and S are in both planes X and Y. EA and FG are parallel. AE and FG are vertical lines and are present on plane X. RS is present at the intersection of the 2 planes.

Explanation:

The lines which together could be perpendicular to RS are EA and FG.

We have to first draw both the planes according to the given information in question.

X is a vertical plane so draw a plane vertical on the horizontal plane that is Y plane. Now plot A and F And G in X plane and R,S in such a way that they  are in both plane so they will be at the intersection of both the planes. Now draw lines from A and F to form lines EA and FG.

Step-by-step explanation:

we get the extreme values of y (a function) by finding the zeroes of the first derivative (that gives us the x-positions) and then using these x values in the original function.

a quadratic function has only one extreme value (1 less than the degree of the polynomial). but 2 zeroes (exactly the degree of the polynomial) - don't mix these two things up.

as the leading coefficient is positive (1), we know that the parabola is opening upwards, and the extreme value will be the vertex and therefore the minimum.

y = (x + 4)² + 6

y = x² + 8x + 16 + 6 = x² + 8x + 22

y' = 2x + 8

2x + 8 = 0

2x = -8

x = -4

(-4 + 4)² + 6 = 0² + 6 = 6

the smallest possible value of y = 6 (at x = -4).

10.

the intercept form of a parabola equation is

y = a(x - p)(x - q)

p and q are the x-intercept values.

in our case we see p = -3, q = 3.

also, we see the vertex being (0, 9), which we need to get "a".

y = a(x - -3)(x - 3) = a(x + 3)(x - 3)

using the vertex coordinates to get a :

9 = a(0 + 3)(0 - 3) = -9a

a = 9/-9 = -1

so, the quadratic equation is

y = -(x + 3)(x - 3) = -(x² - 9) = -x² + 9

11.

I assume the thinking here is : the flight curve of every falling object is a parabola.

the vertex of this parabola is (0, 36), as x represents the time in seconds, and y represents the height in ft.

the vertex form of a parabola is

y = a(x - h)² + k

with (h, k) being the vertex.

y = a(x - 0)² + 36 = ax² + 36

a must be negative, as the fall parabola opens downwards.

for typical fall situations on Earth a = -g/2 ≈ -16 (g being the gravity constant of 32.17405... ft/s²).

so, we have

y = -16x² + 36

for what x is y = 0 ?

0 = -16x² + 36

16x² = 36

x² = 36/16 = 9/4
