Write the equation y-2=6x 3 in y mx b form

Answers

the correct answer is y= 6x+1

Final answer:

The equation y - 2 = 6x is rewritten in the y = mx + b form by simply adding 2 to both sides resulting in y = 6x + 2, where 6 is the slope and 2 is the y-intercept.

Explanation:

The equation y - 2 = 6x is not fully written in the y = mx + b form, which is the standard form of a linear equation where m represents the slope and b represents the y-intercept. To convert the given equation into the y = mx + b form, we need to isolate y on one side of the equation.

First, we will add 2 to both sides of the equation:

y - 2 + 2 = 6x + 2

Which simplifies to:

y = 6x + 2

Now we have written the equation in the desired form, with m = 6 and b = 2. This linear equation represents a line with a slope of 6 and a y-intercept at (0, 2). Graphically, the line can be plotted using these values, and a table of points can be created by plugging various x values into the equation.

Answers

Final answer:

Factorize the given complex expression first into simpler terms (x-2)^2, (x+5)^2 and (x-2)(x+5). After canceling the matching terms, you simplify to get (x-2)/(x+5)

Explanation:

This mathematical question involves the simplification of a fractional expression. The problem can be solved with factoring and canceling out matching terms found in both the numerator and denominator. Step by step solution would be:
((x2-4x+4) can be factored into (x-2)^2.
(x^2+10x+25) can be factored into (x+5)^2.
(x^2+3x-10) can be factored into (x-2)(x+5).
Thus, the whole equation will be converted into
((x-2)^2 / (x+5)^2) x ((x+5) / (x-2)(x+5)).
Cancel (x+5) and (x-2) from the numerator and denominator, which leaves:
(x-2)/(x+5).

Answers

Let's pick on two points. Let's say we pick the first two points which are (1,4) and (0,5,3.5)

The slope formula tells us that

m = (y2-y1)/(x2-x1)
m = (3.5-4)/(0.5-1)
m = (-0.5)/(-0.5)
m = 1

So the slope is 1. We can pick any other two points, run them through the slope formula, and we'll get the same result. 

So that's why the answer is choice C) 1

Answer:

1

Step-by-step explanation:

Step 1: Select 2 points  

(0,3)     (0.5, 3.5)

x1,y1     x2,y2

Step 2: use average rate of change formula

[tex]\frac{y2-y1}{x2-x1}[/tex] = average rate of change

[tex]\frac{3.5-3}{0.5-0} =\frac{0.5}{0.5} =1[/tex]

which of the following functions is graphed below??

Answers

Final answer:

Without seeing the actual graph, it's impossible to provide an accurate response. However, several common types of function graphs have been described.

Explanation:

Unfortunately, without seeing the graph in question, it is not possible to provide an accurate response to your question regarding which function is graphed. However, we can discuss what a few different types of common functions might look like.

A straight line with a positive slope from the lower left to the upper right indicates a direct relationship between x and y values, such as y = x or y = 2x + 1.

A curved graph that resembles a U shape either upright or upside down might suggest a quadratic function such as y = x^2 or y = -x^2.

As for time-graphs, the gradient of a velocity-time graph gives acceleration, while the area under the velocity-time graph gives displacement. The gradient of a position-time graph gives velocity.

Supply and demand curves are graphs used in economics. The supply curve typically slopes upward, and the demand curve usually slopes downward.

In Mathematics and Euclidean Geometry, a piecewise-defined function is a type of function that is defined by two or more mathematical expressions over a specific domain.

Note: The inequality symbol < or > represents a hollow dot (circle).

The inequality symbol ≤ or ≥ represents a solid dot (circle).

Generally speaking, the domain of any piecewise-defined function is the union of all of its sub-domains. By critically observing the graph of the given piecewise-defined function, there is a solid circle above 2 that decreases to the left and a hollow circle above 2 that increases to the right.

In this context, the piecewise-defined function is defined over the following domains;

When the function below is graphed, how many x-intercepts does it have? y = 2x2 - 8x + 5

Answers

It has two x-intercepts because the exponent of the equation is 2 and the graph crosses the x-axis twice

Answer:

2.

Step-by-step explanation:

Please find the attachment.

We have been given a function formula [tex]y=2x^2-8x+5[/tex]. We are asked to determine the number of x-intercepts that our function could have by graphing.

Since our given function is a quadratic function, so it could have at-most two x-intercepts as it will cross x-axis at-most two times.

Upon looking at our attached graph we can see that our given function crosses x-axis at two points, therefore, our given function has two x-intercepts.

A triangle has sides of length 3 cm and 10 cm. What can you say about the length of the third​ side?

Answers

The inequality that represents the third side of the triangle is the third side < 13.

What is inequality?

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.

Given, A triangle has sides of length 3 cm and 10 cm.

From the rule of the triangle, The sides of a triangle rule assert that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.

thus, we can say that

third side < 10 + 3

third side < 13

Therefore, The inequality third side < 13 is used to represent the triangle's third side.

Final answer:

Using the Triangle Inequality Theorem, the third side of a triangle with sides of 3 cm and 10 cm must be greater than 7 cm and less than 13 cm.

Explanation:

To determine the possible length of the third side of a triangle given two side lengths of 3 cm and 10 cm, we use the Triangle Inequality Theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, the third side must be longer than 7 cm (10 cm - 3 cm) but shorter than 13 cm (10 cm + 3 cm).

the graph's maximum is at 33 mpg for reference −0.015(x−55)2+15so just plug it inlet's set y to 0

y=−0.015(x−55)2+15 0=−0.015(x−55)2+15 subtract 15 −15=−0.015(x−55)2 divide both sides by -0.015 1000=(x−55)2
the other maximum is at x=55
and we want the y value
at x=55, y=-0.015(55-55)^2+15 y=-0.015(0)+15 y=15
 the compact has a max of 33mpg and the SUV 15mpg

Given: line DR tangent to Circle O.

If m angle C = 63°, then m angle BDR =

Answers

Based on the given figure above, we can say that the measure of angle BDR is also 63°. R is meant to be tangent to the circle so, this makes the angle BDR equal to C. Angle C is half of the arc as well as BDR. Hope this is the answer that you are looking for. 

Answer:

m∠BDR=63°  

Step-by-step explanation:

It is given that  line DR tangent to Circle O and m∠BCD=63°, then the measure of the angle BDR can be determined as:

Since, angle BDR is made between the chord and the tangent, and we know that the angle between a chord and a tangent through one of the end points of the chord is equal to the angle in the alternate segment, therefore

m∠BCD=m∠BDR=63°

Hence, the measure of angle BDR=63°.
