Does anyone know the answer to this one?
polet [3.4K]

Answer:

\large\boxed{a(x+4)(x-5)=0,\ a\in\mathbb{R}-\{0\}}\\\\\text{for}\ a=1\to\boxed{x^2-x-20=0}

Step-by-step explanation:

\text{If}\ x_1\ \text{and}\ x_2\ \text{are the roots of the quadratic equation}\ ax^2+bx+c=0,\\\text{then}\ ax^2+bx+c=a(x-x_1)(x-x_2).\\\\\text{If}\ x_1\ \text{and}\ x_2\ \text{, then they are the roots of the quadratic equation.}\\\\\text{We have}\ x_1=-4\ \text{and}\ x_2=5.\ \text{Therefore we have the equation:}\\\\a(x-(-4))(x-5)=0\\\\a(x+4)(x-5)=0\qquad\text{for any value of}\ a\ \text{except 0}.

Heba ate \dfrac{1}{12} 12 1 ​ start fraction, 1, divided by, 12, end fraction of a box of cereal. Now the box is \dfrac{3}{4} 4
GrogVix [38]

9514 1404 393

Answer:

  5/6

Step-by-step explanation:

If q is the quantity of cereal in the box before Heba ate some, the problem tells us ...

  q - 1/12 = 3/4

  q = 3/4 + 1/12 = 9/12 + 1/12 = 10/12

  q = 5/6

There was 5/6 of a box before Heba ate.

A walking path across a park is represented by the equation y = -4x + 10. A new path will be built perpendicular to this path. T
kodGreya [7K]

Answer:  y=\frac{1}{4}x-7

Step-by-step explanation:

The perpendicular slope of the line(m) = -\frac{1}{m}:

  • m = -4 ⇒ -\frac{1}{m} =-\frac{1}{(-4)} =\frac{1}{4}

The function formula is y = mx + b, where the y-intercept(b) is found by substituting in the values of a point on the line ⇒ (4, -6):

y=\frac{1}{4}x+b\\-6=\frac{1}{4}(4)+b\\-6=1+b\\b=-6-1=-7

<u>So the perpendicular equation is </u>y=\frac{1}{4}x-7<u>.</u>
