-2r-4=3r+16\ \ \ |+4\\\\-2r=3r+20\ \ \ |-3r\\\\-5r=20\ \ \ \ |:(-5)\\\\r=-4

Answer: r = -4

Isolate the variable "r". Add 2r to both sides, while subtracting 16 from both sides. You will be left with -20=5r. Then you need to divide 5 from both sides. Your answer will be -4=r.

the revenue for the school play is given by: r=-50t^2 + 300t, where “t” is ticket price in dollars. The cost to produce the play
artcher [175]

ANSWER

$3

Or

$4

EXPLANATION

The revenue function is

r =  - 50 {t}^{2}  + 300t

The cost function is,

C=600-50t

In order to break even, revenue must be equal to cost.

600 - 50t= -50 {t}^{2}  + 300t

Group every term on the LHS.

50 {t}^{2}  - 300t - 50t + 600 = 0

50{t}^{2}  - 350t + 600 = 0

Divide through by 50.

{t}^{2}  - 7t + 12= 0

Factor to obtain,

(t - 3)(t - 4) = 0

t = 3 \: or \: t = 4

Consider the quadratic function f(x) = –2x2 + 4x – 2. Find the y-intercept and the equation of the axis of symmetry.
Charra [1.4K]

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = - 2x² + 4x - 2

To find the y- intercept set x = 0

f(0) = 0 + 0 - 2 = - 2 ← y- intercept

The equation of the axis of symmetry is of the form x = c

where c is the value of the x- coordinate the line goes through.

Given the equation in standard form

with a = - 2, b = 4 then the axis of symmetry is

x = - \frac{b}{2a} = - \frac{4}{-4} = 1

Equation of axis of symmetry is x = 1

<h3>What is unit conversion?</h3>

Unit conversion is a multi-step process that involves multiplying or dividing by a numerical factor and, more specifically, a conversion factor.

  • The process may also necessitate selecting the appropriate amount of significant digits and rounding.
  • Different conversion units are employed to measure various parameters.
  1. Measuring Temperature
  2. Measuring Length
  3. Measuring Capacity
  4. Measuring Weight
  • Conversion of units is defined as the process of converting between different units & measurements of a given quantity using multiplication or division.
  • Conversion is the method of changing the amount of one form in terms of mathematics, such as inches to millimeters or liters to gallons.
  • Units are used in the measurement of length, weight, capacity, temperature, and speed.
