Fill in the blanks so that the equation has the solution of x={-4,-1}

Mathematics

alexgriva [62]3 years ago

Answer:

The equation that gave the solution provided is either

x² + 5x + 4 = 0 or k(x² + 5x + 4) = 0 where k = real number

Step-by-step explanation:

Although, the question isn't complete and the blanks to be filled aren't provided, Hence, we can work out a quadratic equation from the solutions for x given

The solutions for x include x = -4 or x = -1

x = -4 or x = -1

(x + 4) = 0 or (x + 1) = 0

So,

(x+4)(x+1) = 0

x² + 4x + x + 4 = 0

x² + 5x + 4 = 0

Hence, the equation that gave this solution is either x² + 5x + 4 = 0 or a constant multiple of the equation obtained; k(x² + 5x + 4) = 0

Hope this Helps!!!

Need help ASAP!!! <br> Multiple choice answers
kobusy [5.1K]

Answer:

A. 16.55

Step-by-step explanation:

What we know is the angle of 38° and the hypotenuse is 21. Before we find x (side b), we have to find side a first. TO find that multiply the sine of 38 by 21.

21 * sin(38)

<em>sin(38) calculates to 0.615661475.</em>

21 * 0.615661475

<em>Multiply 21 by 0.615661475</em>

side a = 12.928890975

Now to find x. Use this to find x: √21² - 12.928890975²

√21² - 12.928890975²

<em>Square both numbers</em>

√441 - 167.156221843

<em>Subtract 167.156221843 from 441</em>

√273.843778157

<em>Find the square root of 273.843778157</em>

x ≈ 16.548225831

x ≈ 16.55, so the answer is A.

What is the slope of the line ? ( question 1/4 )
yanalaym [24]

\huge \rm༆ Answer ༄

First Consider two points ~ (0 , -3) and (-1 , 0)

Now, use the given formula to calculate slope :

  • \sf \dfrac{y2 - y1}{x2 - x1}

  • \sf \dfrac{0 - ( - 3)}{ - 1 - 0}

  • \sf \dfrac{ 0 + 3 }{ - 1}

  • \sf \dfrac{3}{ - 1}

  • \sf - 3

Therefore, the slope of the graph is -3

The given line passes through the points (-2,-4) and (2,2) What is the equation, in point-slope form, of the line that is parall
Morgarella [4.7K]

Answer:

(y-1)=\frac{3}{2}(x+3)


Step-by-step explanation:

The point slope form of a line is (y-y_1)=m(x-x_1) where x_1=-3\\y_1=1. We write  

(y-1)=m(x--3)\\(y-1)=m(x+3)


Since the line is parallel to the line shown it will have the same slope. To find m, count the slope from each marked point on the graph. Count the rise then the run and create a fraction rise/run. The slope is 6/4 which simplifies to 3/2. Now substitute it for m.

(y-1)=\frac{3}{2}(x+3)
