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}.

The length of a field in feet is a function f(n) of the length nin yards. Write a function rule for this situation.
qwelly [4]

Given:

The length of field is n yards.

The length of a field in feet is a function f(n).

To find:

The function rule for this situation.

Solution:

We know that,

1 yard = 3 feet

Using this conversion, we get

n yard = 3n feet

The length of field is n yards. So, the length of the field is 3n feets.

The length of a field in feet is a function f(n). So,

f(n)=3n

Therefore, the required function rule for this situation is f(n)=3n.

20 POINTS PLEASE HELP ASAP
Brut [27]

Answer:

A. If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points

B. From the graph, it is clear that the initial value of the graph is 60 m and it represents the initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.

 

The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min.

The slope-intercept from of the equation of a line that passes through (-2,-13) is y = 5x – 3. What is the point-slope from of t
lisov135 [29]

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

given y = 5x - 3 with m = 5 and (a, b) = (- 2, - 13), then

y +13 = 5(x + 2) ← in point- slope form
