Answer 1

Answer:

y=-5/2x-19/2

Step-by-step explanation:

The vertex of the quadratic equation is (-7,8).

Isolate the variable y for the equation 2x-5y=7

You get y = 2/5x-7/5

The slope we have to find is the inverse of the current slope.

So the slope for the final equation is -5/2.

Then use point slope form to get y - 8 = -5/2 * (x+7)

Then convert it into slope intercept form to get y - 8 = -5/2x - 35/2

Then add 8 to each side to get y=-5/2x-19/2

Answer:

80.73 each month

Step-by-step explanation:

The original price of the computer is $598. It is offered for 25% off. This means you pay 75% of the original price or 0.75(598) = 448.5. The sales price is $448.50. You will pay 8% tax on this price. This means you'll pay 100% of the price plus 8% more. So this is 1.08(448.5) = 484.38.

In total you pay 484.38 over 6 months. This means each month you pay 484.38/6 = 80.73.

Answer:

{y,x} = {-6,-2}

Step-by-step explanation:

/ Solve equation [2] for the variable  y  

 [2]    y = 2x - 2

// Plug this in for variable  y  in equation [1]

  [1]    (2x-2) - x = -4

  [1]    x = -2

// Solve equation [1] for the variable  x  

  [1]    x = - 2

// By now we know this much :

   x = -2

// Use the  x  value to solve for  y

What is the domain of the function y= sqrt3/x ? plese help

Answers

Answer:

Step-by-step explanation:

because x is in the denominator, x cannot equal 0

For this case we have a function of the form [tex]y = f (x),[/tex]where:

[tex]f (x) = \sqrt {\frac {3} {x}}[/tex]

we must find the domain of the function.

The domain is given by all the values for which the function is defined.

Note that "x" is not defined for negative numbers or for zero. Then x can only take strict higher values to zero.

Helaine graphed the equation 12x – 4y = 3. What was the slope of Helaine’s line?\

Answers

Answer:

[tex]\large\boxed{\text{The slope}\ m=3}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the equation of a line in the standard form:

[tex]12x-4y=3[/tex]

Convert to the slope-intercept form:

[tex]12x-4y=3[/tex]         subtract 12x from both sides

[tex]-4y=-12x+3[/tex]        divide both sides by (-4)

[tex]y=\dfrac{-12}{-4}x+\dfrac{3}{-4}\\\\y=3x-\dfrac{3}{4}[/tex]

Answer:  The required slope of the given line is 3.

Step-by-step explanation:  Given that Helaine graphed the following equation :

[tex]12x-4y=3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We are to find the slope of the line.

We know that

the slope-intercept form of a straight line is given by

[tex]y=mx+c,[/tex] where m is the slope of the line.

From equation (i), we have

[tex]12x-4y=3\\\\\Rightarrow 4y=12x-3\\\\\Rightarrow y=\dfrac{12x-3}{4}\\\\\\\Rightarrow y=3x-\dfrac{3}{4}.[/tex]

Comparing with the slope-intercept form, we get

slope, m = 3.

Thus, the required slope of the given line is 3.

Which statement about rhombuses and parallelograms is true?

A) Rhombuses ALWAYS have four equal sides; parallelograms sometimes do not.

B) Rhombuses ALWAYS have four right angles; parallelograms sometimes do not.

C) Parallelograms ALWAYS have opposite sides equal; rhombuses sometimes do not.

D) Parallelograms ALWAYS have opposite sides parallel; rhombuses sometimes do not.

Answers

Final answer:

The correct statement about rhombuses and parallelograms is that rhombuses always have four equal sides while parallelograms sometimes do not. The other options are not true for rhombuses and parallelograms.

Explanation:

The correct statement about rhombuses and parallelograms is option A) Rhombuses ALWAYS have four equal sides; parallelograms sometimes do not. A rhombus, by definition, is a four-sided figure with all sides having equal length while a parallelogram is a four-sided figure with only opposite sides being equal.

Options B, C, and D are incorrect. Rhombuses do not always have four right angles; that is characteristic of a rectangle. Parallelograms always have opposite sides equal and parallel, so C and D are not true.

https://brainly.com/question/35882736

#SPJ3

The correct answer is option (A).The true statement is that rhombuses always have four equal sides, while parallelograms sometimes do not. This characteristic is a key distinction between rhombuses and general parallelograms. The other statements about angles and sides are incorrect regarding rhombuses and parallelograms.

To determine which statement about rhombuses and parallelograms is true, we need to understand their definitions and properties:

Parallelogram: A quadrilateral with opposite sides that are both parallel and equal in length. Opposite angles are equal, and adjacent angles are supplementary.Rhombus: A type of parallelogram where all four sides are of equal length. Additionally, the diagonals of a rhombus are perpendicular and bisect each other at right angles.

Given these definitions, let's evaluate each statement:

A) Rhombuses ALWAYS have four equal sides; parallelograms sometimes do not.
This is correct because a defining property of a rhombus is having four equal sides, whereas a general parallelogram only requires the opposite sides to be equal.B) Rhombuses ALWAYS have four right angles; parallelograms sometimes do not.
This is incorrect because a rhombus does not necessarily have right angles.C) Parallelograms ALWAYS have opposite sides equal; rhombuses sometimes do not.
This is incorrect because rhombuses, as a type of parallelogram, also always have opposite sides equal.D) Parallelograms ALWAYS have opposite sides parallel; rhombuses sometimes do not.
This is incorrect because rhombuses, being parallelograms, always have opposite sides parallel.

Option A) is the true statement as rhombuses always have four equal sides and parallelograms sometimes do not.

what is the horizontal asymptote of the function f(x)= -2x/x+1

Answers

Answer:

-2

Step-by-step explanation:

We have been given a function f(x)=\frac{-2x}{x+1} and we are asked to find the horizontal asymptote of our given function.

Recalling the rules for a horizontal asymptote:

1. If the numerator and denominator have equal degree, the horizontal asymptote will be the ratio of the leading coefficients.

2. If the polynomial of denominator has larger degree than the numerator, then the horizontal asymptote will be the x-axis or y=0.

3. If the polynomial of numerator has larger degree than denominator, then the function has no horizontal asymptote.

Here, the numerator and denominator are of the same degree. So the horizontal asymptote will be the ratio of the coefficients.

Horizontal asymptote = [tex]-\frac{2}{1}[/tex] = -2

what percent is 18 out of 30?

Answers

Answer:

60%

Step-by-step explanation:

p/100 = 18/30

Multiply each side by 100

p/100 *100 = 18/30 *100

p = 60

18 is 60 percent of 30

The number 18 out of the number 30 is 60 percent.

We need to find what percent is 18 out of 30.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here, 18/30

= 9/15

= 3/5

= 0.6

In percentage 0.6×100

= 60%

Therefore, the number 18 out of the number 30 is 60 percent.

A petroleum laboratory technician is working at a petroleum storage depot in the oil-analysis laboratory. The lab tech is running tests on a sample from a 45-gallon oil-solvent mixture that contains 18 gallons of oil.

What is the ratio of the number of gallons of oil to the number of gallons of solvent?

Answers

Final answer:

The ratio of the number of gallons of oil to the number of gallons of solvent is 2:3.

Explanation:

The ratio of the number of gallons of oil to the number of gallons of solvent can be determined by subtracting the number of gallons of oil from the total volume of the mixture and then dividing by the number of gallons of solvent. In this case, the total volume of the mixture is 45 gallons and the number of gallons of oil is 18. So, the number of gallons of solvent is 45 - 18 = 27. Therefore, the ratio of the number of gallons of oil to the number of gallons of solvent is 18:27, which can be simplified to 2:3.
